Retro is back — at least in the CMP’s Standard Modern Military Rifle AR class. Though Service Rifle competition has evolved to allow optics and heavy barrel profiles, the Standard Modern Military Rifle (AR category) is truly a “blast from the past”. Overall weight is limited to 7.5 pounds, and the rifle must be equipped with iron sights (Rule 5.2.3). In addition, the rifle must “be based on the M-16 rifle or be based on an AR design” with “exterior configuration similar [to] the original military or military-type rifle”. See Rules.
With this in mind our friend Dennis Santiago has put together his own AR-platform Standard Modern Military Rifle for matches run under CMP Games Competition Rules. This is not quite a classic AR, as it has a metal free-float handguard (vs. plastic handguards), but it IS light (7.3 pounds), and it does have iron sights — a key requirement for Standard Modern Military class rifles. CMP Rulebooks — All Classes.
Here is Santiago’s CMP Modern Military Rifle (Standard Class) with an ultralight free float tube that has a titanium barrel nut, and mechanical, center-able front sight. The barrel is an AR-Stoner brand 20″-long 1:7″ Government contour chambered in 5.56×45 NATO. Dennis says: “This makes the 7.5-lb weight limit with a few ounces to spare. We’ll see how well it drives soon enough.”
Dennis explains: “The Standard Modern Military (AR) is a category of military-style rifle that shoots the 200-yard, 30- or 50-shot courses alongside the M1 Garands, Springfields, Vintage, and M1 Carbines. This one boasts a Midwest Industries (MI) ultralight Free-float Handguard and a Yankee Hill folding front sight. Any Government contour or thinner profile rifle-length gas tube barrel with a 0.750″ gas block will work.” Colt makes a suitable Government Contour 20″-long, 1:7″-twist barrel, sold by MidwayUSA.
To test the accuracy of his rifle, Dennis fitted a Mantis-X unit on the top of the float tube. The Mantis-X records the movement of the rifle to interpolate shot placements. Dennis reports: “I spent some extra time at the range grabbing a decent zero for my Modern Military rifle. I stuck a Mantis-X on it to record a few shots shooting offhand at the plates at 200 yards. It drives very easily even with no shooting coat or glove.” The Mantis-X is attached just forward of the carry handle, on top of the MI free-float handguard. The Mantis-X works with live fire as well as dry fire. It communicates via BlueTooth to a smartphone App.
Rifle Shoots Well with 77gr Sierra MatchKings
The gun is presently zeroed with 77gr Sierra MatchKing ammunition. Dennis reports his rifle “can easily hold the X-Ring on an SR target for both 100-yard and 200-yard CMP Modern Military Games matches. And it’s fun to shoot!”
CMP Standard Modern Military Rifle (AR Class)
This rifle is built from carefully selected and fitted parts to conform to the CMP’s 7.5-pound weight limit iron-sighted rifle rule. Officially, this is a CMP Standard Modern Military Rifle, Class “A” (AR type).
1. S&W M&P lower receiver
2. White Oak Armament match upper receiver with 1/4×1/4-MOA pinned rear sights
3. AR-Stoner 20″ 1:7″-twist 5.56x45mm NATO Government contour barrel from MidwayUSA*
4. MidWest Industries ultralight free-float handguard with a Titanium barrel nut
5. Yankee Hill Machine folding front sight with a 0.072″ square front pin
6. RRA 2-stage trigger
7. A2 length buttstock
Easy Rifle Build Using Mostly Existing AR Parts, Plus New Barrel and Free-Float Handguard
Dennis was able to put his Modern Military AR together using components he had collected over the years: “Most of these parts were already in my bin of old AR parts available to be recycled. The barrel and free-float handguard were the only new acquisitions.” And with the AR’s modular format, this was an easy build: “Assembly time was about 30 minutes. I’ve done these parts swaps so many times now.”
Key Rules for Standard Modern Military Rifle (AR Type)
Dennis Santiago’s new AR rifle was built as a “Standard U.S. Modern Military Rifle”, Class A (AR Type), as specified in the CMP Games Competition Rules.
5.2.3 Standard U.S. Modern Military Rifles, Class A
Category A Standard Modern Military Rifles must comply with these requirements:
a) Rifles must be based on the M-16 rifle or be based on an AR design;
b) Rifles must be manufactured by a USA manufacturer;
c) Rifles must be equipped with issue-type metallic front and rear sights; rear sights with adjustments finer than one minute of angle are permitted;
d) Total rifle weight, with sights and without sling, may not exceed 7.5 pounds;
e) Rifles may be fitted with a float tube or free-floating handguard. A nonadjustable sling swivel may be attached to the forward end of the handguard; and…
f) The rifle must be chambered for the 5.56x45mm or .223 Remington cartridge.
Also, from Rule 5.2.2:
a) The exterior configuration of the rifle must be the similar to that of the
original military or military-type rifle;
b) The trigger pull may not be less than 4.5 lbs.;
Comments from other Modern Military Rifle Shooters:
“I built a Modern Military [Standard]. It was tough getting below the 7.5-lb [limit]. I had to carve off a bunch of the 20″ barrel diameter but wanted to stay with it for sight radius (over a 16″). I would just as soon shoot that little iron-sighted rifle at 200 yards as my 15-lb Nightforce-scoped Service Rifle. I love that little rifle.” — Kenneth S.
“I’m building one of these that will make 7.5-lb [Standard Modern Military] weight limit, with the long barrel and long sight radius. This has been on my list this winter.” — Tom K.
“We found that turning down a National Match barrel and taking a few inches off of it made a very accurate rifle.” — Jack A.
“My old (complete) A2 upper has been sitting forlorn on a shelf for a couple of years now. Perhaps I need to do a [Standard Modern Military] build of my own.” — Derek D.
Dennis Santiago replied: “Derek — that’s the reason I was attracted to this. I had bought a brand new WOA A2 pin upper receiver to make a new upper then the scope rule was adopted and it was all flat tops. This gives new purpose to the old parts.”
CMP Rules Defining Modern Military Rifles
Standard vs. Unlimited, Class A vs. Class B
There are actually two different classes of Standard Modern Military Rifles, Class A for AR-type rifles and Class B for other military-style rifles, such as the M1A and FN-FAL. Ok, got that? Now, in addition, there is also a second division for UNLIMITED Modern Military Rifles, again with two classes (Class A — AR-type and Class B — other military rifles). These unlimited rifles can have optics, heavier weights, modern-design adjustable-length stocks, and other upgrades. Here is Rule 5.2.2 from the current CMP Games Rifle and Pistol Competition Rules:
British Lee-Enfield Model SHT’22/IV Rifle, courtesy www.iCollector.com.
Our friend Dennis Santiago was a technical advisor for History Channel’s Top SHOT TV show. One of the notable Top Shot episodes involved the “Mad Minute”, a marksmanship drill practiced by the British Army in the decades preceding World War I. Dennis observed that the Top Shot competitors didn’t fare too well in their “Mad Minute” attempts, not scoring many hits in the alloted one-minute time period. That prompted Dennis to give it a try himself — seeing how many hits he could score in one minute with an authentic Lee-Enfield rifle. So, a while back, Dennis ran the drill at a range in California.
Dennis, an active high power rifle competitor and instructor, enjoyed his “Mad Minute” exercise, though he assures us that this takes practice to perfect. Dennis tells us: “Here is a ‘Mad Minute’ drill, done using a period correct Lee-Enfield (SMLE) No.1 Mk III rifle and Mk VII ammo. I got to the Queen’s Regulations (15 hits in one minute) on the second run and put a good group on the target at 200 yards. This is ‘jolly good fun’ to do every once in a while. This is ‘living history’ — experiencing a skill from a time when the sun never set on the British Empire.”
“Mad Minute” was a pre-World War I term used by British Army riflemen during training at the Hythe School of Musketry to describe scoring a minimum of 15 hits onto a 12″ round target at 300 yards within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle). It was not uncommon during the First World War for riflemen to greatly exceed this score. The record, set in 1914 by Sergeant Instructor Alfred Snoxall, was 38 hits. (From WikiPedia.)

History of the MAD MINUTE Commentary by Laurie Holland, UK Shooter
The original military requirement of the “Mad Minute” saw the soldier ready to fire with a round in the chamber, nine in the magazine, safety on. This course of fire is still followed by the GB Historic Breechloading Arms Association and other bodies in their recreated “Mad Minute” competitions.
The first 10 would go quickly, but reloads were critical, this not done by a magazine change as Gary did with the RTM or in a modern tactical or semi-auto rifle, but through slick use of ‘chargers’. It is this aspect which fouls so many of my colleagues up as it is very easy to cause a jam and a large part of 60 seconds can go in sorting it out!
Charger clips were selected for those that just held the rounds firmly enough to stop then falling out, were sand-papered and polished with a stove / fireplace polish called ‘Zebrite’ so that the rimmed rounds would slip through the clips like corn through a goose.
If you’re unfamiliar with the cock-on-closing Enfield action, it seems clumsy. With intensive practice it is very smooth and can be operated incredibly quickly. The trick is to whip the bolt back onto its stop and initiate a rebound movement that takes it and the cartridge well into the chamber thereby reducing the effort required to close the bolt and chamber the round.

“Mad Minute” was a pre-World War I term used by British Army riflemen during training at the Hythe School of Musketry to describe scoring a minimum of 15 hits on a target at 300 yards within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle).

Royal Scots Fusiliers soldiers train with SMLE Mk III Lee–Enfield rifle.
Listed as “Practice number 22, Rapid Fire” of The Musketry Regulations, Part I, 1909, this drill required at least 15 shots on the Second Class target at 300 yards. The exercise was just one of several annual tests to classify a soldier as a sharpshooter, first or second class shooter depending on the points achieved.
Research indicates the Second Class target was a 48″ x 48″ square with 24″ inner circle and 36″ outer circle. The sight mark was a central 12″ x 12″ shape representing a soldier. ALL hits scored points (3 for center circle, 2 for outer circle, 1 for outer square). NOTE: Though some sources say the Mad Minute drill used a 12″-diameter round target, this appears to be a mistake from Ian Hogg’s book “The Encyclopedia of Weaponry”. No other source mentions a 12″ circle, which would be a mere 3.82 MOA. In reality the true drill target was a 48″ x 48″ square, roughly 15 times larger. (From No.WikiPedia.)
There are a variety of print books covering the history and specifications of the Lee-Enfield Rifle:

Some seasons back, before COVID, our friend (and fellow Californian) Dennis Santiago drove across the country, all the way to Ohio. His mission? To attend the CMP National Matches at Camp Perry. For many years, this journey had been an annual pilgrimage for Dennis, who writes: “My goal [was] to spend time with as many of my friends as possible — the friends I’ve known and hang out with throughout the year, the ones I only see once a year at Camp Perry, and the many I’ve only conversed with on social media and will meet in person for the first time. More than anything, Camp Perry is where I come home to my shooting family. My mission is to celebrate my love of this sport with them.”
Here are some photos from Santiago’s successful journey across the USA to Ohio some years ago. After the long cross-country drive, he then headed to the Camp Perry rifle range, with the goal of shooting 10s and Xs across the course.
“Get your kicks on Route 66 — in Manuelito, New Mexico.” — Dennis Santiago
“The heartland is an ocean of corn. It is an amazing thing to see how much food we make.” — Dennis
“Arrived and I’m hungry… at Camp Perry National Rifle Competition, Port Clinton, Ohio.” — Dennis
Advice for First-Time Visitors to Camp Perry
Dennis first competed at Camp Perry in 2016, writing about the experience in his Dennis Talks Guns Blog. Here are some of Santiago’s tips for first-time Perry competitors:
1. Walk the Base. Do not drive around. Get used to walking. Walk from your hut to everything. Walk to the administration buildings. Walk to the ranges. Walk to commercial row. Walk to the CMP North Store. Walk to the CMP or Army trailer to have the triggers of your rifles(s) weighed. Walk. This is your primary mode of transportation while on base.
2. Go Shopping. It’s called Commercial Row. It is the best shopping mall for competitive shooters ever. The sale prices here are Black Friday quality. You stock up on supplies. You can buy elusive powders in quantity with the same lot number. Same with bullets and primers. I stocked up. Everything you need to keep making your pet loads — except brass. This is a service rifle tournament. Pretty much everyone is using LC or WCC cases.
3. Learn about the Perils of Perry. It rains at Camp Perry. Sometimes that rain comes with lightning. When that happens range controls issues an evacuation order. Depending on where you are and how much time you have, you either grab your stuff and make for a sheltered structure or leave your stuff under whatever rain cover you have and leave it there until the storm cell passes.
Coming Soon — The President’s 100 Match
In past years, Dennis has competed in the historic National President’s 100 Match, which takes place on Monday, July 24th this year. This is a huge event — in recent years there were over 1100 ranked competitors from throughout the nation, making this one of the biggest High Power events of the year.

At its upcoming Annual Meetings & Exhibits in Indianapolis, Indiana, the National Rifle Association (NRA) will launch a new activities program for Millennials — young Americans in their 20s and early 30s. The new MRA (Millennial Rifle Activities) program will include a series of special events for Millennials held throughout the nation. These MRA “gatherings” will be unique among NRA competition disciplines. First, all participants in MRA events will receive a participation badge or trophy for showing up. Second, though shooting at targets will be encouraged, no actual gun-handling is required. Millennial participants can choose to watch instead. Finally, for those who do choose to shoot at MRA events, scoring will be optional. Actual scores will be kept confidential, and there will be no published rankings. “At MRA events”, promises an NRA news release, “all participants will be winners!”
The NRA’s new MRA activities program targets “Millennials” — the young Americans raised on video games and the internet. If you’re not familiar with the term “Millennials”, this refers to Americans born between 1980 and 2000. They represent “the first generation that grew up with the internet and the first to have truly incorporated technology into their daily lives.” READ More.
Scoring Optional at Millennials Matches
Creating a competition program for Millennials has been challenging. With short attention spans, Millennials are easily distracted and they lack motivation to prepare or practice. Very self-absorbed, Millennials were raised on “instant gratification” and see themselves as entitled. These personality traits seem to run contrary to the focus, self-discipline, and mindset required for serious competition. Accordingly, the NRA has taken a whole new approach to MRA matches — scores won’t count and the focus will be on participation. Said one member of the NRA Competition Committee: “These were the kids who got ‘participation trophies’ for playing soccer. We are offering the same kinds of rewards. At our Millennial Matches you’ll be acknowledged just for showing up. Scoring will be optional. The emphasis is not on winning, but on participating.”
An NRA spokesman told us: “We’ve done a lot of research into the Millennial group. This demographic is very different than older generations. They expect to be rewarded for participation and they don’t want to be judged by objective standards, such as numeric scores. We’ve also learned that they like to do activities on the spur of the moment and without preparation. That’s why actual shooting will be optional at MRA events. We expect that many participants will arrive completely unprepared — without a gun or ammo. But they can still participate, and be acknowledged… and that’s what it’s all about. We want to get more Millennials involved, whether they actually shoot or not.”
NRA Millennials Outreach Follows Success of NRA Programs for Women
The NRA’s outreach programs have enabled the organization to grow its membership base successfully. For example, in recent years the NRA has significantly expanded the ranks of female members. The NRA now offers a wide variety of programs expressly for women, including Women on Target instructional shooting clinics, and women’s wilderness retreats. The NRA also has a dedicated website for women, NRAWomen.com. This full-featured site promotes women’s activities and recognizes top lady shooters.
Millennials Create Unique Challenges for Match Directors
Dennis Santiago is a seasoned match director with decades of experience running NRA matches. He said that finding a formula for the new Millennials Match “gatherings” has been a challenge: “Designing a competitive course of fire for the new MRA Millennials discipline is not as easy as you would think. Millennials have short attention spans and it is difficult to draw them away from their digital devices. You have to come up with range commands that can attract their attention. We are thinking of sending commands via Twitter, or possibly streaming match instructions over TikTok.”
Dennis also noted that a shooting competition with “optional scoring” is something new and different for the NRA. “The concept of recording and reporting scores was hotly debated. Ultimately we decided to make scoring optional. We concluded that mandatory scoring would probably discourage participation by Millennials. To a generation that has been rewarded for simply showing up, we wanted to create a ‘safe space’ and a non-threatening environment for this new class of competitor.”

The last 18 months has been a frustrating time for hand-loaders, and particular competitive rifle shooters who want the very best components for their match loads. Some of the most popular powders, such as Varget and H4350, are very difficult to find. And the price of primers has skyrocketed, with vendors changing as much as $150-$200 per thousand of popular types such as CCI BR2s. And even brass for popular cartridges, such as 6.5 Creedmoor and 6mmBR has been in short supply. And there are dozens of scam websites now that claim to have primers and powder for sale. Be wary of ANY site that will not take major credit cards, but insist on CashApp, Zelle, Venmo Bitcoin etc. for payment.
Thankfully, there ARE some strategies that can help competitors keep shooting despite the component shortages. First, you can use different types of bullets for practice. Creedmoor Sports offers big-name factory seconds Practice Bullets in multiple calibers. Second, you can look for alternate powder sources if you can’t find the Hodgdon or Alliant powders you prefer. You’ll find a wide selection of Vihtavuori and Accurate powders in stock at many vendors and also look for Shooters World powders. Also if you check local gunstores you may get lucky and find the H4350 or Alliant Reloder 16 you need.
To help fellow shooters overcome the problems of component shortages, our friend Dennis Santiago recently wrote a good article for Shooting Sports USA. This article talks about strategies that can help you keep up your monthly round count. One is to use more available powder and bullets for off-hand practice, where the nth degree of load accuracy is less critical. Dennis also recommends connecting with fellow shooters in your area. You may find that you may trade one hard-to-find component you’ve got for the powder or primers you need. This Editor recently traded some CCI 450 primers for H4350 powder.
We recommend you read the article by Dennis. There are many good suggestions that can help you maintain your live-fire shooting skills, and still attend matches regularly during this time of shortages.

A while back, our friend Dennis Santiago was conducting training for a Southern California Police Department. During a training session one of the unit’s AR15s stopped functioning. The problem — the bolt in the AR rifle broke in half. Dennis states: “They ran the gun dry, broke for lunch, shot it again. They don’t like that. I personally like to flood the bolt wet with lube on training days. It prevents stuff like this. Given that, it’s a simple remove-and-replace fix.”
Here are some of the more interesting comments about this parts failure — an AR bolt that literally sheared in half:
“If I was a betting man [the steel] wasn’t made by Carpenter Steel. They are one of the few companies that use the correct [milspec-steel, C-158] called out on the drawing which they coincidentally developed. Most of the other companies that make [AR Bolts] use different steel with the same heat treat specification as what is called out which gives them the potential of being a little on the brittle side at the upper end of the tolerance. When it comes to the AR platform, bolts are probably the only part of the entire gun where I must admit to being a little bit of a brand snob.” David O’N.
[Editor’s Note: Actually Carpenter Steel does not make AR bolts. They are a steel supplier, and yes Carpenter did develop the original C-158 steel for AR bolts. Here is a contrary view, claiming that AISI 9310 Steel is actually stronger than milspec Carpenter C-158: 9310 Steel for AR Bolts.]
“Dry bolt and carrier shouldn’t cause that. Looks like a big pressure spike. What kind of ammo…?” Guy G.
Reply from Dennis: “55gr factory ammo. Piles of it.”
“Is that the new two-piece bolt everyone’s been talking about LOL?” — Darren R.
“Let me guess…the PD called you in cause they didn’t know why it stopped going ‘pew pew’?” — Jim O.
Reply from Dennis: “I was there today for qualifications. It broke during the rifle phase. Simple enough to fish the bolt parts out of the action. The training didn’t miss a beat. I have an armory full of the things.”

Retro is back — at least in the CMP’s Standard Modern Military Rifle AR class. Though Service Rifle competition has evolved to allow optics and heavy barrel profiles, the Standard Modern Military Rifle (AR category) is truly a “blast from the past”. Overall weight is limited to 7.5 pounds, and the rifle must be equipped with iron sights (Rule 5.2.3). In addition, the rifle “be based on the M-16 rifle or be based on an AR design” with “exterior configuration similar [to] the original military or military-type rifle”. See Rules.
With this in mind our friend Dennis Santiago recently put together his own AR-platform Standard Modern Military Rifle for matches run under CMP Competition Rules. This is not quite a classic AR, as it has a metal free-float handguard (vs. plastic handguards), but it IS light (7.3 pounds), and it does have iron sights — a key requirement for Standard Modern Military class rifles.
Here is Santiago’s CMP Modern Military Rifle (Standard Class) with an ultralight free float tube that has a titanium barrel nut, and mechanical, center-able front sight. The barrel is an AR-Stoner brand 20″-long 1:7″ Government contour chambered in 5.56×45 NATO. Dennis says: “This makes the 7.5-lb weight limit with a few ounces to spare. We’ll see how well it drives soon enough.”
Dennis explains: “The Standard Modern Military (AR) is a category of military-style rifle that shoots the 200-yard, 30- or 50-shot courses alongside the M1 Garands, Springfields, Vintage, and M1 Carbines. This one boasts a Midwest Industries (MI) ultralight Free-float Handguard and a Yankee Hill folding front sight. Any Government contour or thinner profile rifle-length gas tube barrel with a 0.750″ gas block will work.” Colt makes a suitable Government Contour 20″-long, 1:7″-twist barrel, sold by MidwayUSA.
To test the accuracy of his rifle, Dennis fitted a Mantis-X unit on the top of the float tube. The Mantis-X records the movement of the rifle to interpolate shot placements. Dennis reports: “I spent some extra time at the range grabbing a decent zero for my Modern Military rifle. I stuck a Mantis-X on it to record a few shots shooting offhand at the plates at 200 yards. It drives very easily even with no shooting coat or glove.” The Mantis-X is attached just forward of the carry handle, on top of the MI free-float handguard. The Mantis-X works with live fire as well as dry fire. It communicates via BlueTooth to a smartphone App.
Rifle Shoots Well with 77gr Sierra MatchKings
The gun is presently zeroed with 77gr Sierra MatchKing ammunition. Dennis reports his rifle “can easily hold the X-Ring on an SR target for both 100-yard and 200-yard CMP Modern Military Games matches. And it’s fun to shoot!”
CMP Standard Modern Military Rifle (AR Class)
This rifle is built from carefully selected and fitted parts to conform to the CMP’s 7.5-pound weight limit iron-sighted rifle rule. Officially, this is a CMP Standard Modern Military Rifle, Class “A” (AR type).
1. S&W M&P lower receiver
2. White Oak Armament match upper receiver with 1/4×1/4-MOA pinned rear sights
3. AR-Stoner 20″ 1:7″-twist 5.56x45mm NATO Government contour barrel from MidwayUSA*
4. MidWest Industries ultralight free-float handguard with a Titanium barrel nut
5. Yankee Hill Machine folding front sight with a 0.072″ square front pin
6. RRA 2-stage trigger
7. A2 length buttstock
Easy Rifle Build Using Mostly Existing AR Parts, Plus New Barrel and Free-Float Handguard
Dennis was able to put his Modern Military AR together using components he had collected over the years: “Most of these parts were already in my bin of old AR parts available to be recycled. The barrel and free-float handguard were the only new acquisitions.” And with the AR’s modular format, this was an easy build: “Assembly time was about 30 minutes. I’ve done these parts swaps so many times now.”
Key Rules for Standard Modern Military Rifle (AR Type)
Dennis Santiago’s new AR rifle was built as a “Standard U.S. Modern Military Rifle”, Class A (AR Type), as specified in the CMP Competition Rules.
5.2.3 Standard U.S. Modern Military Rifles, Class A
Category A Standard Modern Military Rifles must comply with these requirements:
a) Rifles must be based on the M-16 rifle or be based on an AR design;
b) Rifles must be manufactured by a USA manufacturer;
c) Rifles must be equipped with issue-type metallic front and rear sights; rear sights with adjustments finer than one minute of angle are permitted;
d) Total rifle weight, with sights and without sling, may not exceed 7.5 pounds;
e) Rifles may be fitted with a float tube or free-floating handguard. A nonadjustable sling swivel may be attached to the forward end of the handguard; and…
f) The rifle must be chambered for the 5.56x45mm or .223 Remington cartridge.
Also, from Rule 5.2.2:
a) The exterior configuration of the rifle must be the similar to that of the
original military or military-type rifle;
b) The trigger pull may not be less than 4.5 lbs.;
Comments from other Modern Military Rifle Shooters:
“I built a Modern Military [Standard]. It was tough getting below the 7.5-lb [limit]. I had to carve off a bunch of the 20″ barrel diameter but wanted to stay with it for sight radius (over a 16″). I would just as soon shoot that little iron-sighted rifle at 200 yards as my 15-lb Nightforce-scoped Service Rifle. I love that little rifle.” — Kenneth S.
“I’m building one of these that will make 7.5-lb [Standard Modern Military] weight limit, with the long barrel and long sight radius. This has been on my list this winter.” — Tom K.
“We found that turning down a National Match barrel and taking a few inches off of it made a very accurate rifle.” — Jack A.
“My old (complete) A2 upper has been sitting forlorn on a shelf for a couple of years now. Perhaps I need to do a [Standard Modern Military] build of my own.” — Derek D.
Dennis Santiago replied: “Derek — that’s the reason I was attracted to this. I had bought a brand new WOA A2 pin upper receiver to make a new upper then the scope rule was adopted and it was all flat tops. This gives new purpose to the old parts.”
CMP Rules Defining Modern Military Rifles
Standard vs. Unlimited, Class A vs. Class B
There are actually two different classes of Standard Modern Military Rifles, Class A for AR-type rifles and Class B for other military-style rifles, such as the M1A and FN-FAL. Ok, got that? Now, in addition, there is also a second division for UNLIMITED Modern Military Rifles, again with two classes (Class A — AR-type and Class B — other military rifles). These unlimited rifles can have optics, heavier weights, modern-design adjustable-length stocks, and other upgrades. Here is Rule 5.2.2 from the current CMP Games Rifle and Pistol Competition Rules:
Our friend Dennis Santiago was doing some dry firing practice recently, using a SCATT sensing device. This electro-optical unit shows a trace of barrel/muzzle movement on a computer screen, allowing a shooter to improve his hold and aiming. With practice, you get steadier, and learn to break the shot more perfectly. Top position shooters worldwide use this system. Dennis tells us: “This is my dry fire practice set up. I’m working on my approaches to the target today. You need the SCATT’s traces to see the feedback of what’s going on.” Here is one trace from Santiago’s morning training session:
Dennis trains indoors at his house: “The set-up is in a room with the target about 15 feet away mounted on a scope stand at eye height and aligned. This morning, it’s focus and trigger control. My offhand form is gonna get there bit by bit. There are many details to turn into instincts.”
SCATT MX-02 Training System
The SCATT MX-02 is an electronic shooter training system that is capable of operating outdoors with live, centerfire ammunition, at distances from 25 yards to 600 yards. Tony Chow tested this product for AccurateShooter.com. As fitted to his AR-15 Service Rifle, Tony concludes this is a very useful tool that can help High Power competitors refine their technique and shoot higher scores. FULL REVIEW HERE.
How the SCATT MX-02 Works
The SCATT sensor mounted on the end of the barrel has a digital camera that recognizes the black bullseye in the target, even in broad daylight outdoors. Using the bullseye as a reference, the SCATT software tracks the movement of the muzzle relative to the center of the target. The unit can plot these movements as a continuous trace, which appears on a monitor as a squiggly, colored line. By sensing the exact moment of shot release, the SCATT can also interpolate relative shot placement (for a single shot or series of shots) — but this is not the same as an electronic target which actually records the exact shot impact location on the target.
Pro shooter Kirsten Joy Weiss demonstrates the SCATT MX-02 electronic training system:
The system traces and records valuable information such as hold pattern, shot hold duration, follow-through, recoil pattern, and much more. The latest SCATT MX-02 systems can be used both indoors and outdoors up to 300 meters (and possibly more). READ FULL SCATT MX-02 TEST HERE.
SCATT traces reveal muzzle movements during the aiming process.

When we first ran this story a while back, it spurred a hot debate, with strong opinions on both sides of the issue. Some guys argued vehemently that volumetric powder dispensing was best — citing the experience of short-range benchresters, most of whom still throw their charges. Others say weighing your charges is best, so long as you have a very precise, and very repeatable scale. Many of the top F-Class and 1000-yard shooters now weigh their charges to the kernel.
Most competitive long-range shooters weigh powder charges for their handloads. Some even use ultra-precise magnetic force restoration scales to load to single-kernel tolerances. But is weight-based measuring always the best way to fill a case with powder? Another option is volumetric charging. This method fills a precisely-sized cavity with powder and then dumps the charge into the case. A Harrell’s rotary powder measure works this way, as does the sliding powder filler on a Dillon progressive press.
For long-range applications, most people believe that precise weighing of powder charges is the best way to achieve optimal accuracy and low ES/SD. However, those short-range Benchrest guys do pretty darn well with their thrown charges, at least at 100 and 200 yards.
Our friend Dennis Santiago recently observed something that made him scratch his head and wonder about weighing charges. His AR-15 match rifle shot better with volumetric (cavity-measured) charges than with weighed charges dispensed by an RCBS ChargeMaster. Here’s what he reports:
Cavity vs. Dribble (Dennis Santiago Report) I had the chance to compare nominally identical ammunition loaded two ways. These were all .223 Remington match loads using 77gr Sierra Match Kings over 23.4 grains of Hodgdon Varget. Same gun. However I loaded some ammo with charges dispensed with a Lee cavity-style powder measure while other rounds were loaded with powder weighed/dispensed by an RCBS ChargeMaster. The cavity-drop ammo (with powder dropped from the Lee unit) was consistently better than the weighed-charge ammo. I have no idea why…
So, ladies and gentlemen — what do you think? Why did Mr. Santiago’s volumetrically-charged ammo shoot better than ammo filled with weighed charges? What’s your theory? Gary Eliseo suspects that Dennis’s Chargemaster might have been drifting. What do you think? Post your theories in the comments area below.

Our friend Dennis Santiago is at Camp Perry this summer. Yesterday (7/29/2019) he competed in the historic National President’s 100 Match. This is a huge event. in recent years, there have been over 1000 ranked competitors from throughout the nation, making this one of the biggest rifle events of the year.
The President’s 100 Rifle Match is richly steeped in history. This unique match was first held in 1878. Here’s the view from the line at 600 yards:
The 2017 President’s 100 Rifle Match was a tightly-fought affair, with the top five shooters separated by just two points. SSG John Cogshall (ARNG) shot superbly to take the top position and President’s Rifle Trophy. The top 100 competitors overall in the President’s Rifle Match are designated as the President’s 100. They receive President’s 100 medallions and certificates. GET full match results.
Top Five Shooters at 2019 National President’s 100 Match
1. SSG John Cogshall (ARNG) 390-14X (Trophy Winner)
2. SGT Thomas Colyard (SC, USMC) 389-16X
3. Sean Prosser (PA) 389-12X
4. Greg Troxell (TX) 388-11X
5. John Hefner, (TX) 388-13X
Note: SFC Brandon Green, USAMU, who holds the course record at 400-20X, also shot a 388-13X but was ranked sixth by tie-breaker.
President’s 100 Shoot Off! — The Top 20 shooters face off while everyone watches, wishing the best for every one of them. This is what attending a family gathering is for us.
President’s 100 Course of Fire
There is a three-yardage, four-stage Course of Fire for the President’s Rifle Match Course of Fire. Firing is done on the SR target at 200 and 300 yards and the MR target at 600 yards. Scores in stages 1-3 determine the President’s 100 and the final rankings of competitors in 21st place and below. Scores in stages 1-4 determine the match winner and the final rankings in places 1-20. If there is a tie for first place (equal total and X-count), the tied shooters will continue to fire one-shot-at-a-time until the tie is broken. No sighters are permitted in National Trophy Rifle Matches.
Origins of the President’s Match The National Rifle Association’s President’s Match was instituted in 1878, as the American Military Rifle Championship Match. In 1884, the name was changed to the President’s Match for the Military Rifle Championship of the United States. It was fired at Creedmoor, New York until 1891. In 1895, it was reintroduced at Sea Girt, New Jersey. Today, the match is held at Camp Perry, Ohio.
The President’s Match was patterned after the Queen’s Match for British Volunteers. That British competition was started in 1860 by Queen Victoria and the NRA of Great Britain to increase the ability of Britain’s marksmen following the Crimean War.
The tradition of making a letter from the President of the United States the first prize began in 1904 when President Theodore Roosevelt personally wrote a letter of congratulations to the winner, Private Howard Gensch of the New Jersey National Guard.
After a hiatus in the 1930s and 1940s, The President’s Match was reinstated in 1957 at the National Matches as “The President’s Hundred.” The 100 top-scoring competitors in the President’s Match were singled out for special recognition.

Research indicates the Second Class target was a 48″ x 48″ square with 24″ inner circle and 36″ outer circle. The sight mark was a central 12″ x 12″ shape representing a soldier. ALL hits scored points (3 for center circle, 2 for outer circle, 1 for outer square). NOTE: Though some sources say the Mad Minute drill used a 12″-diameter round target, this appears to be a mistake from Ian Hogg’s book “The Encyclopedia of Weaponry”. No other source mentions a 12″ circle, which would be a mere 3.82 MOA. In reality the true drill target was a 48″ x 48″ square, roughly 15 times larger. (From

The NRA’s new MRA activities program targets “Millennials” — the young Americans raised on video games and the internet. If you’re not familiar with the term “Millennials”, this refers to Americans born between 1980 and 2000. They represent “the first generation that grew up with the internet and the first to have truly incorporated technology into their daily lives.”
