Dry-firing practice can benefit all competitors, particularly sling-shooters. However, for AR15 Service Rifle shooters and High Power competitors using AR-based “spaceguns”, dry-firing is complicated by the charging handle location — pulling back on the handle requires that you move your head placement on the rifle. In addition, extensive AR dry-firing can cause pre-mature wear of an AR’s firing pin. AR shooters take heart — now there are products that allow you to dry-fire your AR more easily, without breaking position, and with no adverse effects on the firing pin.
Creedmoor AR15/M16 Dry-Firing Device Creedmoor Sports offers a Delrin dry-firing device that allows you to reset your AR trigger with a very short pull of the charging handle — plus you don’t have to break position. Machined from solid Delrin, the dry-fire device is inserted into the bolt carrier and limits the swing of the hammer, allowing unlimited dry-firing without the risk of firing pin damage. The trigger pull is unchanged and the shooter can reset the trigger mechanism by cycling the charging handle a mere one-quarter inch or so. The shooter can reset his trigger without breaking position and the lessened impact of the hammer allows the shooter to better evaluate his sight picture and follow-through. Creedmoor’s AR-15/M16 Service Rifle Dry-Fire Device, item #C1051, retails for $18.95
Other AR Dry-Firing Devices MidwayUSA offers a similar Delrin dry-firing device for ARs. Like the Creedmoor unit, this TMA-made device fits in the bolt carrier group and protects the firing pin from damage. The orange unit slips between the buffer and bolt, and permits the trigger reset with only a quarter-inch movement of the charging handle. During storage the device can also provide a safety function by preventing the hammer from hitting the firing pin. But, we caution, don’t leave your gun loaded presuming this device, by itself, will make the gun safe. MidwayUSA’s orange Delrin AR dry-firing device, item #872223, costs $17.29.

Newly-issued CMP and NRA competition rules now allow Service Rifle competitors to use optics with a max magnification of 4.5X. That’s right, Service Rifle shooters can now use scopes, not just iron sights. These rule changes have created a need for a new type of riflescope, one optimized for today’s “optics-allowed” Service rifle discipline.
March Optics has just introduced a brand new 1-4.5x24mm scope designed for Service Rifle competition and tactical applications. With ultra-sharp ED glass, this new March scope should set the standard for AR-friendly 4.5X optics. This compact variable-power scope offers ideal eye relief for AR-type rifles, along with plenty of windage and elevation range. The new March 1-4.5x24mm scope is a second focal plane optic with 1/4-MOA clicks. Weight, without caps, is 18.7 ounces. The scope comes standard with a speed lever for quick zooming throughout the magnification range.
The optics experts at March tell us: “This scope was specifically designed for the Service Rifle match shooter. New rules were announced in October 2015 that allow scopes with magnification up to 4.5X power. This 1-4.5x24mm scope also makes a great optic for SWAT work as well as for a sporting rifle. Oversized tactical turrets allow for easy windage and elevation adjustments. The high quality ED lenses provide superior image resolution that make March the best in its class”. The MSRP of this high-end scope is $2750.00. March is offering a 15% OFF special now for regular purchasers*. This scope will be on display at SHOT Show Booth 549.
* March offers a 20% off MSRP price on this scope for Law Enforcement/Military members (current and retired), Pros, and U.S. Team members.

The most important 2016 CMP rule change allows 4.5X (max) optical sights for Service Rifle shooting.
The new 2016 rulebooks for CMP-governed Service Rifle, Pistol and CMP Games shooting events have just been released. There are some very important changes for 2016, including the authorization of scopes for Service Rifle competition. You can download the new Rulebooks for free with the links below. NOTE: The most important 2016 Rules changes are indicated with underlined text in the new Rulebooks.
The big rule changes in the 2016 CMP competition rules concern the modernization of CMP Service Rifle standards. Starting in 2016, Service Rifle competitors will be able to choose between service rifles with traditional metallic sights or rifles with telescopes with a maximum of 4.5X magnification. These scopes may be fixed-power or variable, with max 4.5 power zoom. This rule change was coordinated with a similar rule change adopted by the NRA.
The CMP states: “The decision to legalize optical sights on service rifles was taken after several years of discussion and a recognition that U.S. military personnel no longer use anything but optical sights on their military rifles. CMP Service Rifle rules have traditionally tried to keep abreast of military rifle and training developments so opening Service Rifle shooting to optical sights became an inevitable change. To quote one comment received by the CMP, “It is very difficult now to say that as-issued ‘AR-15 or M16′ does not include telescopes.”
Another major change in the CMP Service Rifle rules will allow the use of a much wider variety of M16/AR15-type rifles. Legal service rifles will no longer be restricted to rifles that rigidly comply with the M16 service rifle profile. Starting in 2016, Service Rifles can be any “M16 U. S. Service Rifle or a similar AR15 type commercial rifle that is derived from the M16 service rifle design” and that complies with these restrictions:
Chambered for the 5.56 x 45 mm (.223) NATO cartridge.
Designed or modified for semi-automatic fire only.
Have either a gas-impingement system or a piston-operated gas system.
Have a barrel that is no longer than 20 inches, or 21 5/8 inches if the barrel has a flash suppressor.
Must use the same upper receiver and barrel for the entire match.
Have a trigger pull of at least 4.5 pounds.
Quad rails or similar hand guards are permitted, but the front sling swivel location must be fixed at 13 ¼ inches (+/- ½ in.) ahead of the forward edge of the magazine well (8.0 inches on M4 configured rifles).
Use standard service magazines or commercial equivalents.
Have a fixed or collapsible butt-stock that may vary in length and even be adjusted between firing stages. Butt-plates or cheek-pieces may not, however, be adjustable.
Have a standard A1 or A2 pistol grip.
Extended bolt releases and mirror-image left-hand receivers will be permitted.
No Weight Limit For Service Rifles
Before issuing its new rules, the CMP solicited comments. A substantial majority of competitors’ comments supported allowing optical sights and the broadening of the Service Rifle rule. The one rule change that most shooters opposed was a proposed weight limit for Service Rifles with optical sights. After considering these comments, the CMP Rules Committee rejected the the Service Rifle weight limit proposal. Accordingly, in 2016, there will be no weight limits for Service Rifles, whether they have optical or metallic sights.
Iron Sights and Optics Will Compete in the Same Class
The CMP considered having optics-equipped Service Rifles in a separate classification. That idea was rejected. So, for 2016 there will be ONE CLASS for all Service Rifles (both iron-sighted and scoped). The CMP observed that “the arguments for having one unified competitor category competing together for EIC points and Distinguished Badges prevailed. Having separate categories and one Distinguished Badge would have created nightmare administrative challenges. Having two categories and separate Distinguished Rifleman Badges for optical and metallic sighted rifles would have become a formula for diminishing the prestige of the traditional Distinguished Rifleman Badge. The final CMP decision was to keep one strong, unified Service Rifle event instead of two smaller categories[.]”
Rule Change Concerning Malfunctions (No more Alibis)
Another major Service Rifle rule change will abolish allowing extra time or refires for malfunctions. This change will save time because malfunction refires effectively double the length of time needed for rapid-fire relays in big matches. The main reason for this change is to place more responsibility on competitors for having rifles and ammunition that function with complete reliability. Comments received by the CMP concerning this change showed that it is controversial, but a majority of shooters supported the change. One shooter wrote: “The elimination of “alibis” is long overdue. It was always most frustrating to me when it takes longer to shoot rapid fire than slow fire.”
Story Tip by Shiraz Balolia of Bullets.com. We welcome reader submissions.
The CMP has just released proposed 2016 Competition Rules. There are a number of important proposed changes, some quite controversial. Topping the list are rule changes that would allow optics for service rifles and “modern military rifles” (MMR). If these changes are adopted, Service Rifle shooters and modern military rifle shooters will be able to use scopes up to 4.5X power. Rifle weight limits will be increased slightly to allow for the optics and the definition of “Service Rifle” will be liberalized to allow more AR variants. In addition, collapsible or adjustable-length stocks will be allowed.
We want to stress that these new rules have NOT been set in stone — not yet at least. The CMP issued its notice of Proposed 2016 Rule Changes to inform competitors and invite feedback. The CMP asks that comments/questions be sent to competitions @ thecmp.org, not later than November 13, 2015.
Major Proposed Rule Changes
1. Optical Sights For Service Rifles
The CMP states: “For several years, the CMP has recognized that optical sights are the wave of the future for Service Rifle shooting. Military recruits today do all of their training with optical sighted rifles. Service Rifle rules have traditionally tried to keep abreast of military rifle and training developments so opening Service Rifle shooting to optical sights became an inevitable change.” The 2016 rules will, for the first time, permit M16/AR15-type rifles to have optical sights (fixed power or zoom) with a maximum magnification of 4.5X and an objective lens no larger than 34 mm. There will not be a separate class for scope-sighted rifles. Instead, competitors will have a choice of using either a scope-sighted rifle that weighs no more than 11.5 pounds or a metallic-sighted rifle that will continue to have no weight limit.
2. More Options For M16/AR15-Type Rifles
Since accurized Service Rifles first came into popular use in the 1950s and 1960s, those rifles, whether M1s, M14s, or M16s and their commercial equivalents, have been rigidly defined. Legal M16-type service rifles had to retain the external profile of an M16A2 or M16A4 rifle and could only have modifications that were explicitly permitted in the rules. All this will change in 2016. The CMP plans to liberalize the Service Rifle rules to encourage greater participation. A wider variety of commercial AR-platform rifles will be allowed so long as they meet basic requirements, such as 20″ max barrel length, 5.56x45mm (.223 Rem) chambering, and a trigger pull of at least 4.5 pounds. Notably, the rifles can have either a gas-impingement system or a piston-operated gas system. Collapsible stocks will be allowed. However butt-plates and cheek-pieces may not be adjustable. (See all Requirements HERE).
3. Optical Sights for Modern Military Rifles (CMP Games)
One of the fastest growing rifle competition categories is for Modern Military Rifles. There are two classes, one for M16/AR15 platform rifles and one for a broad range of other military rifles. Competitors who compete in Modern Military Rifle Matches will now have the option of using optical sights with a maximum magnification of 4.5X. To make allowance for the increased weight of telescopes, the weight limit for AR-type rifles was increased to 8.5 pounds and for M-14/M1A rifles to 10.0 pounds. (This is a CMP Games limit — a different Rule than the Service Rifle Rule).
4. Stocks for Modern Military Rifles
Butt-stocks on these rifles may vary in length and collapsible or adjustable-length stocks will be allowed. Butt-stocks, however, may not have butt-plates or cheek-pieces that adjust up or down.
No Changes for Pistol, Vintage Sniper, or Rimfire Sporter Competitions
While big changes are slated for the Service Rifle and MMR disciplines, the CMP is not making significant rule changes for other popular CMP shooting sports.
Pistol Rules Are Unchanged
Except for permitting service pistols to have a Picatinny rail below the barrel, the Service Pistol and 22 Rimfire Pistol rules adopted in 2015 are unchanged.
Vintage Sniper Rifle Team Match Rules Are Unchanged
According to the CMP, Vintage Sniper Rifle Match rules “have stabilized nicely in the last two years” so there will be no 2016 rule changes for the Vintage Sniper two-man team event.
Rimfire Sporter Rifle Rules Are Unchanged
The most popular rimfire rifle match in the country continues to attract impressive numbers to its matches. Like the Vintage Sniper Rifle Team Match, these rules have now stabilized so that there are also no 2016 rule changes in Rimfire Sporter.
Dennis DeMille is a past Camp Perry National Champion, and he still one of the nation’s top Service Rifle shooters. Since retiring from the U.S. Marine Corps, Dennis has served as the General Manager of Creedmoor Sports. Some years back we had the chance to interview Dennis at the old Creedmoor offices in Oceanside, California. With his decades of competitive experience, Dennis has a wealth of knowledge. In this 3-minute interview, Dennis shares insights into the High Power shooting game. He discusses the most effective ways to train for competition, the fundamentals of good marksmanship, and how to recognize and perfect your natural point of aim. Dennis also offers solid advice on how to get the best “bang for your buck” when choosing shooting accessories for High Power and Across the Course competition.

In the just-released June 2015 issue of Shooting Sports USA, you’ll find an excellent profile of SFC Emil Praslick III, a legendary figure in American shooting. As a marksmanship instructor and coach for the USAMU, Praslick has been a mentor for many of America’s greatest marksmen. Praslick has also served as a wind coach for many civilian teams over the years, guiding them to victory in high-level championship events. SFC Praslick plans to retire later this year, when SFC Shane Barnhart will take over as coach of the USAMU Service Rifle Team.
In a wide-ranging Shooting Sports USA interview with writer John Parker, SFC Praslick offers many interesting insights. Here are some highlights (after the jump):
You have to love it when a prototype product not only performs well, but actually wins a match. For some time, Criterion Barrels has been working on a match-grade barrel for vintage Lee-Enfield rifles. It looks like they got things right…
Over the Easter weekend the New Zealand Service Rifle Association held its annual national service rifle competition. Coming first in the Classic Bolt Action class was Wellington’s Nicole McKee shooting a Lee-Enfield with a new, prototype Criterion barrel. Nicole’s rifle was built by her husband Duncan, a vintage rifle expert who specializes in accurizing the No. 4 and SMLE actions. Nicole’s .303 British handloads featured Hornady 174gr FMJ Boattail bullets (SKU: 3131) pushed by 47.0 grains of ADI 2209 (H4350). ADI 2209 has become the top go-to powder for .303 British shooters in New Zealand.
Report by John Morgan-Hosey
Civilian Service Rifle (CSR) is a shooting sport in the United Kingdom shot with bolt action rifles and ‘Straight-Pull’ derivatives of semi-auto centerfire rifles. Why do the UK shooters use manual-operating versions of popular self-loaders? Well, that’s because of legal restrictions. Civilian ownership of semi-auto centerfire rifles was banned in the United Kingdom in 1987.
Give credit to the ingenuity of competitive shooters in the UK. The ban on semi-autos has not stopped shooters from adapting modern rifles such as the AR15. In fact, CSR is the UK NRA’s fastest growing shooting discipline. There are four classes for competitors:
1. Historic Class — Vintage Rifles, mostly Lee Enfields with iron sights.
2. Iron Sights Class — all non-Historic Rifles with Iron (open) sights.
3. Practical Optic Class — Rifles with bipods (and scopes 4.5X or greater magnification).
4. Service Optic Class — Rifles without bipods (and scopes with no more than 4.5X power).
Surprisingly, shooters in the Service Optic Class dominate these matches. So you don’t need a high-magnification scope or a bipod to do well. The most popular rifles are modified AR-platform rifles. These are set-up in the UK with no gas system to ensure they comply with our laws. Side-charger cocking handles are fitted to allow the rifles to be operated easily while in the shooting position. You can see in the photo above a modified AR with the Union Jack on the buttstock. Notice the bolt handle on the right. This opens and closes the bolt.
This video clip shows the side-charging ARs in use.
Note the side bolt handle that cycles the action on this non-semi-auto AR.
Here shooters advance 100 yards to engage the targets at the next firing line.
Dave Wylde Sets Impressive Record at the Civilian Service Rifle League Match.
The last matches in the 2014/15 CSR League took place on Sunday, 5 April. With final places in all four classes up for grabs, the fine weather and light winds made for some impressive scores, none more so than Dave Wylde in Service Optic Division. Dave scored a mighty impressive 246 (of a possible 250) in the PM Match. Breaking 235 is tough enough and scoring over 240 a rarity with the match includes standing snap shooting at 100 yards, a sitting rapid at 200 yards, and prone snap shooting at 300 yards with and two run downs to raise the shooters heart rate.
The most popular class, Service Optic, had Peter Cottrell retaining the trophy for the fourth consecutive year with a score of 993. Adam Chapman pushed him hard all season to finish a close second on 987 points, with Bill Ellis, one of the most consistent CSR shooters, third with 972.
Civilian Service Rifle Grows in Popularity
As CSR continues to grow in popularity, the sale of ‘Straight-Pull’ AR-platform rifles is increasing year after year. Accordingly, the United Kingdom NRA is allocation more range space at the Bisley National Shooting Centre to accomodate the increasing number of competitors.

Many of our readers use AR-type rifles for Service Rifle matches, varmint hunting, 3-Gun competition, or defensive use. AR-platform rifles can be configured in a multitude of ways to suit the application. But if you plan to put together your own purpose-built AR rifle, how do you get started?
For AR Do-It-Yourselfers, we suggest reading Glen Zedicker’s book, the Competitive AR15 Builders Guide. Following Zedicker’s New AR-15 Competitive Rifle (2008), the Builders Guide provides step-by-step instructions that will help non-professional, “home builders” assemble a competitive match or varmint rifle. This book isn’t for everyone — you need some basic gun assembly experience and an aptitude for tools. But the AR-15 Builders’ Guide provides a complete list of the tools you’ll need for the job, and Zedicker outlines all the procedures to build an AR-15 from start to finish.
Along with assembly methods, this book covers parts selection and preparation, not just hammers and pins. Creedmoor Sports explains: “Knowing how to get what you want, and be happy with the result, is truly the focus of this book. Doing it yourself gives you a huge advantage. The build will honestly have been done right, and you’ll know it! Little problems will have been fixed, function and performance enhancements will have been made, and the result is you’ll have a custom-grade rifle without paying custom-builder prices.”
The Competitive AR-15 Builders Guide is not available from most large book vendors. However, Amazon still has a few copies in stock. CLICK HERE to order.

“Gain-twist” refers to a form of barrel rifling where the twist rate gets tighter over the length of the barrel. For example, a gain twist barrel might start with 1:12″ twist and finish with 1:8″ twist. There is some evidence that gain-twist rifling can deliver more velocity (compared to a conventional barrel) with certain cartridge types. There have also been claims of increased accuracy with some types of bullets, but such claims are more difficult to quantify.
Gain-twist rifling is not new. This form of rifling has been around for a long, long time. The first gain-twist barrels appeared in the late 1800s. However, in the last few years, there has been increased interest in gain-twist barrels for both short-range and long-range competition.
Video Explains Gain Twist Rifling
Radical Extreme Gain Twist Barrel Design
In this video from our friend John M. Buol Jr., gunsmith John Carlos talks about a fairly radical gain-twist barrel design for high power and service rifle shooters. Produced by Bartlein Barrels, this gain-twist barrel starts with a 1:14″ twist and finishes with a 1:6.8″ twist at the muzzle (See 1:50 time-mark). Carlos believes that this type of barrel delivers higher velocities while providing excellent accuracy for a wide range of bullet weights. In .223 caliber, the gain twist works with the 75-77 grain bullets used on the “short course” while also delivering excellent accuracy with the longer 80-90gr bullets used at 600 yards and beyond. Velocity is the important bonus for long-range use. Carlos says the gain twist barrels deliver greater muzzle velocity, allowing a 90 grain bullet to stay well above the transonic zone, even at 1000 yards. (See 4:50 time-mark.)
This 1:14″ to 1:6.8″ gain-twist barrel is the product of much experimentation by Carlos and Bartlein. Carlos states: “We’ve varied all sorts of internal dimensions, such as the land height, and the groove depth. We’ve tried 5R rifling and 4-groove rifling, and we’ve worked with various rates of twist, and I believe we have it down really well right now.”
In this video, John Carlos explains the history of gain-twist rifling, and he explains how modern Bartlein gain twist barrels have been developed in recent years for both benchrest and High Power applications. If you are interested in barrel technology and design, take the time to watch.
USAMU Service Rifle shooter/instructor SSG Brandon Green set a new national record this past week, shooting a 500-33X in the individual Aggregate, National Match Course (NMC) with metallic sights. Green was near-perfect in the 200-yard Rapids, shooting an amazing 100-9X. Green was shooting a Tubb 2000 bolt-action rifle chambered in 6XC. He set the new record using Norma factory ammo. Yep, this was factory 6XC ammo, right out of the box.
National Record Score Card of SSG Brandon Green
SSG Green is the current NRA High Power National Champion and Interservice Rifle Champion. He and the rest of the USAMU rifle team have trained hard for the 2014 season. Yet Brandon joked about his record-setting performance, noting that the record was shot with his “back-up” gun. On his Facebook page, Brandon posted: “500-33X NMC. Not positive, possibly a record [Editor: Yes it was.] Not too bad for a #2 gun.” Not too bad indeed, Brandon. Congratulations on this achievement. This bodes well for Green’s goal to win a second straight National High Power Championship at Camp Perry this summer.
Note: After setting a National Record with 500-33X during the individual match with his Tubb 2000, SSG Green followed with a 498 the following day using a Service Rifle during the team match. Remarkable.

The April 2014 Digital Edition of Shooting Sports USA is now available online (for free). This month’s issue has many articles of interest to competitive shooters. The cover story From Smallbore to High Power, profiles Col. Denise Loring, an international smallbore competitor who recently made the transition to High Power shooting. This is an excellent article.
Col. Loring “compares and contrasts” smallbore and High Power, providing fascinating insights into the differences between the disciplines: “I was very nervous about having only two sighters for NRA High Power matches. Then, I heard about the CMP style of HP where there are no sighters and could not believe you could shoot a match without them. We have unlimited sighters in smallbore and I took full advantage of that aspect. In NRA conventional smallbore you can even return to the sighter bull once you have begun shooting for record.”
Biathlon — Shooting at 180 Beats Per Minute
There is also an interesting feature on Biathlon shooting. This tutorial covers the basics of this challenging Olympic sport that combines Nordic skiing and smallbore position shooting. This in-depth article profiles the top athletes, explains the rules, and provides interesting details of the hardware: “Most athletes use a Fortner (straight-pul bolt) action, although traditional bolt-action guns are allowed. The rulebook regulates biathlon rifles by minimum width, trigger resistense, dimensions and shape[.] Magazines may be spot-checked before or after an event to ensure they contain only five rounds[.]”
