TECH TIP: How to Take-Down and Maintain Your AR Bolt

AR15 Bolt Disassembly

Accurate, modular, and supremely versatile, the AR15 is America’s favorite semi-auto rifle. But let’s face it, the AR is a maintenance hog. The AR’s gas tube blows carbon and soot right into the middle of the bolt assembly where it cakes on to the metal. The AR bolt also has many tiny parts, and small recesses, which must be cleaned regularly. This author has seen numerous ARs fail simply because there was gunk (dried lube, carbon, brass shavings) in the ejector slot or extractor spring recess.

A Clean AR is a Happy AR — Whether You Run ‘Wet’ or ‘Dry’
There are various schools of thought when it comes to maintaining an AR. Some folks prefer to run their AR “dry” with minimal lube on the lugs and friction surfaces. Other shooters prefer to run their ARs “wet”, with lots of lube. But whatever your preference, you need to clean your AR regularly. And nothing is more important than the AR’s bolt/carrier assembly. Because it is involved in feeding, firing, and extracting, the AR-15 bolt/carrier assembly can be considered the most critical portion of the AR-15 from a maintenance standpoint.

Bolt Take-Down Guide on Top Quark Blog
The editor of the Top Quark Blog has created an excellent illustrated AR15 Bolt Take-Down Guide that shows how to disassemble an AR15 bolt and carrier for regular cleaning. Even if you’re an experienced AR15 shooter, you can learn something from this page (sample at right), and you may want to bookmark it for future reference. The photos are large and clear and there are helpful hints for each step of the process.

The author knows his stuff and offers some important insights. For example, he notes that “Extractor springs in most AR15 bolt assemblies are fairly weak, and this can lead to various extraction-related failures. One of the few high points about Colt assemblies is their usage of higher-strength extractor springs. You can tell the difference by looking at the inner plastic insert. ‘Normal’ springs feature a blue plastic insert, Colt strong springs have a black insert.”

There is one notable oversight on this page — the author doesn’t cover disassembly and cleaning of the ejector assembly. This is actually quite important. A few small brass shavings, combined with carbon and lube in the ejector slot, WILL cause malfunctions. In fact, when this editor is called to diagnose problem ARs, the first things I look at (after swapping magazines) are the ejector recess and the slot for the extractor. Clogged ejectors are responsible for fail-to-ejects and other jams. It is essential that you keep the ejector hole clean. Old, gooey lube residues mixed with carbon and tiny brass shavings in the ejector recess will create all sorts of problems. As shown in the diagram below, it is simple to remove the ejector (#6) and ejector spring (#5), by drifting the ejector retaining pin (#4).

6mm ARC Cartridge Featured on Shooting USA Tomorrow

6mm ARC brownells bolts cartridge loaded ammunition hornady

Hornady’s 6mm ARC cartridge will be featured on tomorrow’s Shooting USA broadcast. Optimized for the AR-15 platform, the 6mm ARC (Advanced Rifle Cartridge) was developed in response to a request from the Department of Defense, according to Hornady Marketing Director, Neil Davies: “The DOD guys wanted a platform built that would give them all of the advantages of the .308 [7.62×51] and try to get rid of some of the disadvantages, [such as the heavier] weight of the entire system. So they went from an AR-10 system to an AR-15 system. But they also wanted to engage targets, not just across the street or inside a room, but maybe across a valley.”

SHOW TIMES: This Shooting USA Episode airs Wednesday, June 30, 2021 at 9:00 PM Eastern and Pacific; 8:00 PM Central. If you miss the regular broadcast, you can stream the show at any time on Vimeo for $0.99 per episode.

In June 2020, Hornady introduced the 6mm ARC, a new SAAMI cartridge optimized for AR-platform rifles*. The new 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. That pushed-back shoulder does reduce case capacity (and velocity), but we assume Hornady did that to create a shorter, proprietary chamber so people could not simply neck-down Lapua 6.5 Grendel brass, as has been done for years with Robert Whitley’s outstanding 6mm AR wildcat.

If you are intrigued by the 6mm ARC, you’ll find the products you need at Brownells — uppers, barrels, bolts, and magazines. Brownells also sells Hornady-made 6mm ARC factory-loaded ammo, but most varieties are out-of-stock right now, as is the 6mm ARC brass. More brass and ammo should arrive soon. Midsouth is also taking brass/ammo backorders. For general information, see 6mm ARC Info Page.

What Is the 6mm ARC Cartridge?
6mm ARC brownells bolts cartridge loaded ammunition hornadyThe 6mm ARC cartridge is a new SAAMI-spec cartridge based on the 6.5 Grendel case necked down for 6mm bullets, with the shoulder moved back 0.030. Yes it is designed to run in AR15-platform rifles. You’ll need a new barrel, bolt, and mags. If you already have an AR chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else — bolt, magazines, gas system – is compatible with 6mm ARC.

▶ Official SAAMI Cartridge (not wildcat)
▶ Fits standard AR15-platform rifles
▶ Fits Short/Mini action bolt rifles
▶ Efficient short, fat case design
▶ 30-degree case shoulder

For more INFO, see 6mm ARC Info Page.

What Do I Need To Shoot the 6mm ARC?
Faxon and Ballistic Advantage are already producing barrels, with more manufacturers sure to follow. All the other required components are already on the market for 6.5 Grendel rifles. Aero Precision already offers complete 6mm ARC uppers.

Sunday Gunday: AR Service Rifle — Focus on Ammo & Reloading

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels
The 600-yard target has an X-Ring 6 inches (1 MOA) across, while the 10-Ring spans 12 inches (2 MOA).

The following article is about reloading for NRA/CMP Highpower Rifle competition and is geared toward competitors shooting the AR15 Service Rifle. In Highpower Rifle competition, shooters fire in four stages: Standing slow-fire at 200 yards, Sitting rapid-fire at 200 yards, Prone rapid-fire at 300 yards, and Prone slow-fire at 600 yards. Competitors use a sling for support in all positions but standing. A typical AR15 Service Rifle sports a 20″ free-floated barrel and a 4.5-pound trigger. Service Rifle scopes are limited to maximum power of 4.5X.

Thoughts on Loading for Service Rifles, Particularly for 600 Yards

by Danny Arnold, Team CMP
Article originally published in CMP Shooting News

Before we get started, I want to stress that all of the information that follows is geared toward the .223/5.56 Service Rifle. That doesn’t mean that there’s nothing here for anyone else, but the .223/5.56 Service Rifle platform is where I’ve spent the majority of my time, so here we go.

There is only one “Perfect” 600–yard load for my rifle, True or False? This example is more anecdotal than scientific, but it provides some food for thought….

Team CMP spent the early part of March competing in the Orange Blossom Regional. As soon as we got on the range, Sara Rozanski (Team CMP member) started having problems with her 600-yard ammunition. Nearly 1/3 of her cases were exiting the chamber minus the primers. I offered to swap my ammunition for hers, suspecting that my Wylde chamber would be more forgiving than her CLE chamber — a solution that seemed to solve the problem. At least neither of us was blowing primers!

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels

Sara’s ammunition was a factory load using a well-known 80+ grain bullet with an unknown primer and powder, using brass from a respected manufacturer. My load was a different brand of 80-grain bullet, with my choice of powder and primer, all in brass made by someone else. Given the color of the primers, the only thing that our ammunition could possibly have had in common was the brand of powder… maybe. So, how did we shoot?

Sara and I shot the two-person team together and the entire 2,400 Aggregate, although on different relays. Sara’s combined 600-yard score was 780-28X (97.5%). Mine was a 783-24X (97.87%). Our scores were never more than two points apart on any of the four days. Keep in mind that we were using each other’s ammunition the entire time.

So, we had different barrels, chambers and ammunition, but similar results. That goes back to the idea that a good load will perform similarly if fired in a good barrel.

Are We Too Focused on Ballistic Coefficients (BCs)?
The revailing wisdom has always trended toward loading the highest-BC bullet we could find and pushing it as fast as possible. Back in the early ’90s when I got started with the AR15, the 80-grain Sierra was state of the art. Actually, I picked up all of my Leg points with it, although today it looks a bit dated — kinda like me.

So, the question I’ll pose is this: Would you rather shoot a high-BC bullet that groups 3/4-MOA (minute of angle) or a lower-BC bullet that groups into one-half-MOA traveling 50 feet-per-second faster? The reason that I posed this question is a situation I found myself in a decade ago. Our coach decided that he wanted us to pair-fire some 600-yard for practice. Unfortunately, I hadn’t gotten the memo and all that I had available was my normal short-line ammunition, loaded with a 77-grain bullet. The shooter I was paired with was using a higher-BC bullet than I was, but in the end, we both shot 198s.

Admittedly, using 77-grainers meant that coach had to work a little harder to keep us together on target, but it was a teaching moment for me. I knew that my upper shot 77s better than the available bullets in the 80-grain range, so I cranked out a windage table for the 77-grain bullet at 600 yards and shot those for the rest of the season. After all, the wind blows ALL bullets around. It’s just a matter of knowing what YOUR bullet is doing.

With the shortages that we’re experiencing right now, a lighter bullet may be all that you have available for the 2021 season. That doesn’t mean that you’re disadvantaged though.

Loading High-BC Bullets
In the past decade, several bullets have appeared that weigh 80-grains or more. One thing that many of them have in common is a very sharp nose profile, whether metal or polymer. The question is: Are you using the right seating stem?

The jacket material in the bullet’s nose is very thin. If you section a bullet, you’ll find that there is a surprising amount of air space in the nose. If you’re using older seating dies, your seating stem may be contacting the bullet nose too close to the tip, where the jacket is the both thinnest and is unsupported by the lead core. This can manifest itself either as a deformation at the very tip of the bullet or as a circular dent around the bullet nose that you can see and feel with your thumbnail. I think we can all agree that denting a bullet is usually considered a bad thing.

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels

One company goes so far as to recommend their proprietary seating stem for use with their high-BC bullets. Other companies leave it up to you to find a seating stem that will allow the bullet nose to go deeper into the seating stem, moving the contact point further down the bullet where the jacket is thicker and supported by the core material.

Seating Depth and Bullet Preferences
Some bullets don’t mind some “jump” into the lands, but some really do. Unfortunately, manufacturers don’t tell you much about that. Your chamber configuration (Wylde, CLE, or some hybrid of the two) and the bullet that you choose will determine your optimal seating depth. Long and short of it, a quality measuring tool to determine seating depth is a necessity these days. Keep in mind that if you’re doing this with a brand new barrel, the throat is likely going to change slightly in the first 200 rounds and may need to be re-measured. Actually, since all of your short range ammunition has to be loaded to magazine length, you’re probably better off developing your short range loads before starting on long range load development. That gives the throat a chance to wear in a bit on a new barrel.

Brass Prep — Why It Is Important
When match-grade AR15s first arrived on the scene, it was amazing how little it took to get them to shoot well. Other than making sure that I had brass from the same lot and running it through a set of match-grade dies, I did nothing. Of course, we were also using a post front sight. Was the occasional bad shot me, the rifle, the load or just an archaic sighting system?

Transitioning to optics has caused me to reconsider how and what I do in my reloading process: That, and having some extra time on my hands to experiment.

A little (or a lot) of time spent with a neck turning tool, a primer-pocket uniformer and a flash-hole reamer will quickly show you how consistent brass is by manufacturer and even by individual lot. That exercise also makes the prices charged for high-quality brass seem ridiculously cheap. That doesn’t mean that I advocate neck-turning or other uniforming practices, nor do I advocate spending scandalous amounts of money on long-range brass. However, our sport is about consistency. The consistency of your brass is a matter of choice, whether you choose to simply segregate cases by weight (cheap option), neck turn (labor intensive) or open your wallet a little wider for premium brass.

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels

Weighing Charges vs. Throwing with Powder Measure
To measure or weigh? For a long time, I used a powder measure to throw all of my 600-yard loads. The powder I was using metered well, and the results downrange didn’t justify the extra time spent with a scale. That was in the day of iron sights though. Nowadays, I’m throwing my charges and trickling up to the desired weight as measured on a scale that weighs to a 100th of a grain.

To quantify the difference between individually weighing each charge versus throwing charges with a powder measure, I weighed six kernels of powder that I trickled into the pan and then dumped them into the hopper. Going through that process 10 times, I came up with an average weight of .08 grains for six kernels. Next, I threw 50 charges for weighing using my powder measure. If I felt the measure hanging up as it cut kernels, I put the charge back into the hopper without weighing it.

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels
That’s six kernels of powder sitting in the pan — average weight .08 grains.

Those 50 smoothly-thrown charges varied .26 grains from lowest to highest, with the majority varying no more than .16 grains from highest to lowest. If the desired weight was exactly in the middle, at worst you’d be .13 grains (9-10 kernels) low or high, with the majority being off no more than .08 grains (6 kernels) above or below the desired charge weight. Is that enough to send a shot outside the 2-MOA 10-Ring? Probably not.

Has more consistent brass and weighing charges to one-hundredth (0.01) of a grain added up to higher scores? Honestly, this question is hard to answer. Looking at the results on paper at 200 yards, using a powder that meters well combined with a consistent touch on the loading lever doesn’t appear measurably different than meticulously weighing each and every powder charge. Looking back over my 600-yard plots however, I can see a trend toward a group that is closer to X-Ring height.

Since the bullseye is widest at the center, shooting groups that are the height of the X-ring gives you more room for error when the wind is blowing. That can translate into higher 600-yard scores.

How You Load Your Ammunition vs. How You Load Your Rifle
The loading/chambering cycle of the AR-15 is, in a word, violent. You have a relatively heavy bolt and carrier assembly under power of a stout buffer spring slamming forward to chamber each round of ammunition. By design, those rounds were supposed to be held securely by the magazine feed lips until the bolt stripped them off the follower. Obviously, due to their overall length, 600-yard loads can’t be chambered that way. Although the barrel extension is funnel-shaped, it’s also got a lot of “teeth” ringing the inside of it (see below).

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels

Whether you’re using a standard magazine or a single-round loading device (SLED), dropping a round in the loading port and releasing the bolt is an act of faith in that you’re trusting the bullet to arrive in the chamber undamaged.

Ask yourself, how many times have you seen someone drop a round on the follower, press the bolt release and watch as the bolt jammed on a cockeyed round? If that happens once every 100 tries, how many times did the bolt close on a scratched, dented, or misaligned bullet? Could that be the cause of the occasional errant shot?

My technique is to drop each round on top of the SLED and then push it slightly forward with my finger, partially chambering it before releasing the bolt. Admittedly, some people may be unable to do this due to body configuration or left-handedness, but why go to all the trouble of loading “perfect” ammunition and then damage it on the way into the chamber?

Now that we’ve covered bullets, brass, and assorted errata we can move on to discussing loads for 600 Yards…

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels highpower target
The NRA Highpower 600-yard target has a 6-inch (1 MOA) X-Ring, and a 12-inch (2 MOA) 10-Ring.

Load Development for 600 Yards

Finding a load for 600 yards is a lot like finding a load for short range. Once I decide on a bullet, powder, primer, velocity range and a measured guesstimate of seating depth, I load 10 rounds of each test load, increasing in 0.2 (2/10) grain increments. I test them from the prone position at 200 yards. Ideally, I want to see two loads that are 0.2 (2/10) of a grain apart that shoot almost identical groups. The load that I choose will fall in between the two best shooting loads that I tested. If the first load is XX.2 grains and the second is XX.4 grains, my chosen load will be XX.3 grains.

Why develop loads in 0.2-grain (tenths) increments if I have a scale that measures in 0.01-grain (hundredths) increments? Or, why not test in 0.1-grain increments?

For me, working in 0.2-grain increments gets me to the results quicker. Also, there is a difference between accuracy and consistency in this scenario. Developing loads in 0.2-grain increments gets me to an accurate load. Producing that load using a scale that accurately measures to .01-grain insures a consistent load, assuming that I do my part.

Once I’ve settled on a load, it’s time to play with seating depth, if I choose to. If I’m lucky and the groups are acceptable as-is, I won’t do anything. If I think there’s room for improvement, I’ll experiment a little. Depending on the bullet, changing the seating depth by a couple of thousandths one way or the other may change the group size. During this phase of testing, it’s a good idea to chamber a round and see if the entire round will then extract. If you leave a bullet stuck in the throat, your rounds are too long. Finding that out at a match can ruin an otherwise good day.

High Power service rifle AR15 reloading 600 yard Danny Arnold powder kernels

Another thing to keep in mind is that your barrel is not static. Every round fired has an effect on the throat, vaporizing and scouring away metal until the distance the bullet travels before meeting the rifling measurably increases. If you have chosen a bullet that shoots best when close to the lands, you’ll need to periodically re-measure and possibly change your bullet seating depth to maintain that optimal relationship.

The Elephant in the Room — User Skill Level

There’s really not a delicate way to put this, so I won’t try. There’s little point in spending time and effort developing a load that shoots into half-MOA off the bench if you’re only capable of shooting 2 MOA using a sling right now.

That doesn’t mean that there’s no hope. On the contrary, it just means that your time and effort is better spent practicing with some good short-range ammunition on reduced targets at a 100 or 200-yard range. At that distance, wind is not a factor and your technique can be improved more quickly so you’re in a position to benefit from that ½ MOA ammunition.

Trigger Options for AR-Platform Rifles — Standard and Modular

AR15 AR10 Trigger Geissele Timney Elftmann 2-stage ALG Defense modularTrigger images from PrimaryArms.com, which sells all the triggers reviewed here: Geissele, Elftmann, Timney, and ALG Defense.

Are you thinking of upgrading the trigger system for your AR-platform rifle? There are dozens of options available, from $45 up to $350. Thankfully, Brownells has created video reviews of some of the more popular AR trigger options from Timney, Geissele, and ALG Defense. And we included a video review of the highly-regarded Elftmann Match Trigger. If you want the best solution for Service Rifle competition, you might favor the Geissele. For ease of installation, it’s hard to beat the Timney, a “drop-in” module. Like the Timney, the super-smooth Elftmann is a drop-in module. At $249.99 from Brownells it’s pricey, but it is one of the best AR triggers out there. If you’re on a tight budget, the best “bang for your buck” may be the “Perfected Mil-Spec” ALG trigger at $49.00.

Multiple AR Triggers, including Elftmann and Geissele, Reviewed

Though pricey ($249.00 at PrimaryArms.com), we really like the Elftmann AR trigger. It combines the best of both worlds — the precision and smoothness of the Geissele with the Timney’s ease of installation. This single stage trigger is user-adjustable from 2.75 to 4 pounds pull weight. It is offered with either straight or curved trigger blade. Primary Arms says: “The amazingly short take-up, glass-rod crisp break and [near-zero] over-travel can be compared to the finest custom 1911 triggers.”

Geissele Enhanced Two-Stage Trigger

Geissele makes a variety of quality AR trigger sets both single-stage and two-stage. Many High Power competitors like the two-stage Geissele trigger. This delivers a repeatable, controlled pull through the first stage with a very clean break in the second stage. The Super Dynamic Enhanced Trigger, shown above, features a distinctive, trigger blade. Reviewer Thomas Conroy says: “The flat surface is very easy to press against. Both stages are light and very distinct.”

Timney Drop-In Trigger Module

This trigger module is available for both the AR15 and the AR10 platform (see above video). Timney triggers are easy to install and come with multiple pin size and pull-weight options. Reviewer Thomas Conroy confirms that the single-stage Timney “breaks cleanly and crisply. This trigger is modular, meaning that the trigger, sear, hammer, and spring are all encased in a bright, shiny yellow aluminum housing.”

ALG Defense Trigger — Higher-Quality Basic AR Trigger

ALG AR15 AR trigger brownellsAccording to Thomas Conroy, ALG triggers “are the perfected version of the standard, non-adjustable mil-spec original trigger. They have the same geometry, but are made to higher quality standards, and come with … hardened and smoothed-out sear contact surface to eliminate all grittiness.” These are also offered in a nickel-boron coated version. Available for under $56.00, the ALG is a well-made, low-cost option for shooters who want a better factory-type trigger system.

Sunday GunDay: World’s Lightest AR Rifle — 3.8-Lb OIP Gen 2

GunsAmerica Battle Arms Battlearms AR15 AR OIP Gen 2 light weight

One of the most radical black rifles ever created wowed the crowd at the SHOT Show Range Day back in 2019. At the Boulder Rifle & Pistol Club outside Las Vegas, Battle Arms Development showcased a true “UltraLight AR”. With Titanium and carbon fiber components, the Battle Arms OIP Gen 2 AR-platform rifle weighs just 3.8 pounds unloaded. Compare that to 7.5 pounds (or more) for a typical AR-15.

Battle Arms 3.8-Lb Titanium/Carbon OIP 2 — World’s Lightest AR

At the Boulder City Range GunsAmerica Digest Managing Editor True Pearce talked with one of the Battle Arms gun designers who helped created this unique rifle, claimed to be the world’s lightest AR (yes it is lighter than ARs with polymer lowers). READ GunsAmerica Battle Arms OIP 2 Review HERE.

In the video below, True Pearce shows the key features of the $3290.00 Battle Arms OIP 2. Then he tests its function shooting offhand at steel targets. Despite its low mass, and exotic components, the Battle Arms OIP 2 AR carbine performed flawlessly.

The video above features the Battle Arms OIP GEN 2 AR that weighs just 3.8 pounds. To save weight, this carbine features a carbon fiber handguard and various titanium parts including a Titanium muzzle brake. Look carefully at how even small controls have been modified to save ounces.

GunsAmerica reported: “Battle Arms has done a lot of work to find all the ounces that can be spared to make this gun as light as possible.” Even at just 3.8 pounds, the gun is very controllable during rapid fire. Despite a steep $3290.00 MSRP, the first run of Battle Arms’ sub-4-lb GEN 2 OIP sold out. That proves that “light is right”, as least in the AR carbine market.

The Concept Behind the OIP — Why Go Ultra-Light

Recoil Magazine featured an earlier model OIP rifle back in 2016 (Issue 21). This design was later refined into the current OIP Gen 2 version. Recoil’s writers explained the concept behind this unique design:

Battle Arms OIP Rifle — How Low Can You Go…

“The OIP had its genesis as a simple idea to build a lightweight gun that just plain worked. Dave Lake and Matt Babb of Bentwood Gunsmithing spent years perfecting the concept, incorporating the latest components where they existed and working with companies to customize parts that didn’t. They wanted a well-balanced gun with an optimized operating system and literally no excess — to be as light as humanly possible.

Bentwood didn’t want to utilize polymer receivers and worked with Battle Arms Development to develop a super lightweight receiver set with intricate machining to shave as much weight as they could. They investigated some more exotic material choices, but found them to be prohibitively expensive.”

Battle Arms OIP 2 Owner’s Review on TFB

Last year, The Firearm Blog (TFB) published an extensive review of the Battle Arms OIP 2. TFB writer/tester Rusty S. had purchased this OIP 2 rig with his own funds — making a serious $3290.00 investment.

After using the rifle in the field, Rusty concluded: “Objectively, the Battle Arms Development OIP 2 is a very well put together, reasonably accurate and very lightweight rifle. It has proven to be reliable, durable, and soft shooting despite its lightweight configuration. Subjectively, the OIP 2 has proven to be the rifle I most often bring with me into the backcountry with the exception of during deer and elk hunting season. It’s nice to have a 500-yard-capable rifle with me that weighs so little. All that being said, the amount that the OIP2 will lighten one’s wallet by will be a real sticking point for most prospective buyers.” Rusty added: “At this price point, I would appreciate some sort of ultra lightweight flip-up iron sights. I also don’t think the rear of the buttstock is as ergonomically optimal as it could be.”

Product Description from Battle Arms
[The Battle Arms OIP 2 is] the lightest, purpose-built, no compromise, production ultralight survival carbine[.] It took years in R&D, engineering and multiple U.S. Patents to create the most robust and reliable lightweight AR platform on the market. Building something that is not only lightweight but all the while not sacrificing strength and performance is the ultimate secret of the Battlearms OIP.

Every component, shy of a few detents and springs, are custom built and designed to work together as a complete system. No, you will not find a parts gun here….The OIP utilizes a patented OIP buffer system in conjunction with a lightweight titanium bolt carrier with ArmorTi finish for durability. It is balanced with a custom mid-length gas system and a specially designed titanium THUMPER compensator.

New in Gen 2 is the user-configurable M-LOK carbon fiber handguard and a carbon-fiber pistol grip that weighs barely one ounce. A new titanium billet CNC-machined bolt catch and a lightweight single-side Clutch charging handle are just a couple more of the new upgrades to the OIP. The rifle was designed to be an optics-ready carbine, providing a single stretch of Picatinny rail in the optimal spot for a red dot sight while eliminating the unnecessary weight of the rail elsewhere. The patented, lightweight 7075-T6 billet aluminum receivers are not simply skeletonized and hollowed out but is carefully engineered with structural consideration. The technology and engineering that foes into the OIP® Ultralight Rifle bring forth the next evolution of the AR platform.

Triggers for AR Platform Rifles — Single-Stage and Two-Stage

AR15 Timney drop-in trigger two-stage 2-stage single stage

AR-platform rifles are fun and versatile, but the standard, mil-spec triggers leave much to be desired. They tend to be gritty, with creep and heavy pull weight. One of the easiest, most effective AR upgrades is a trigger group swap. An improved fire control group makes a huge difference. There are many aftermarket trigger options for the AR platform rifles. Choose single-stage or two-stage, either standard trigger assembly or unitized “drop-in” trigger, such as those made by Timney or Triggertech.

When upgraded with a precision trigger and match barrel, AR-platform rigs work great in NRA High Power competitions (Photo from NRA Blog, at Camp Perry).

AR15 Timney drop-in trigger two-stage 2-stage single stageTwo-Stage vs. Single-Stage Triggers
Two-stage triggers have two separate movements. The first stage offers a light, spring-loaded pressure that works against the shooter’s pull until stopping at the second stage – this is called “take-up”. If there is no spring pressure, it is known as “slack”. Should the shooter continue to pull the trigger once he’s arrived at the second stage, the mechanism will operate like a single-stage trigger from there until engaging the sear and firing the gun. Some shooters prefer a two-stage trigger because it allows a mental preparation (first stage) before the final decision to “break the shot”.

Single-stage triggers feature no take-up or slack, as they begin engaging the sear as soon as the shooter begins pulling the trigger. Some competitive shooters prefer the two-stage trigger because of the feedback it provides during its first stage, while other shooters, including those using their rifle in tactical scenarios, may want the surety of a single-stage trigger, ready to engage and fire once their finger is inside the trigger guard. Regardless of preference, a good trigger will feature minimal creep and should be free of grittiness, providing a smooth, even break.

Drop-In Trigger Assembly vs. Standard Trigger Group
Once you decide between a single-stage or two-stage trigger, you can choose between standard and drop-in trigger groups. Standard trigger groups feature all the fire control group parts separated, and need to be pieced together and installed much like a mil-spec trigger, while drop-in trigger are pre-assembled and contained within a casing that simply drops in to the receiver and accepts the pins, hence the name.

After-Market Trigger Comparison

Some shooters prefer drop-in triggers due to the ease of installation, while others opt for standard groups so they can access the components individually for cleaning adjustment or replacement. If one piece of a drop-in trigger fails, you’ll need to either replace the entire unit or send it to the manufacturer for repair, whereas you may be able to simply replace the broken component of a standard trigger without needing a whole new trigger set.

Trigger Terminology — “Creep”, “Stacking”, “Overtravel”
“Creep” or “travel” is the distance the trigger moves between the end of take-up and when the trigger breaks to fire the fun. Too much creep can affect accuracy, but no creep can be unsafe, as the shooter may not be prepared to fire. “Stacking” occurs when the trigger weight actually increases during travel — this shouldn’t happen. Lastly, “overtravel” is the distance the trigger continues moving back after the gun fires.

Fundamentals — Sight Alignment and Trigger Control

Marksmanship Fundamentals iron sights USAMU

This video from the U.S. Army Marksmanship Unit focuses on two key fundamentals of marksmanship: 1) Sight Alignment; and 2) Trigger Squeeze. This video can assist any Service Rifle or metallic sights shooter. The USAMU instructor explains: “You’ve probably heard a lot about fundamentals — Breathe, Relax, Aim, Squeeze… Well that gives a shooter a lot to think about. Here we teach two main firing tasks: 1) align the sights, and 2) squeeze the trigger without moving the rifle. This allows the shooter a much more simplified format.”

The following tips are transcribed from the video:

Task One: Sight Alignment
Sight alignment is the process of putting the tip of the front sight post, the rear aperture, and the shooter’s eyeball all on the same plane. It’s very important to maintain the tip of the front sight post centered in the rear aperture. Just .002″ of deviation can cause a miss at 300 meters. Allow your eye to do its job. While firing, the focus should remain on the tip of the front sight.

Task Two: Trigger Control
Your second firing task is [to] fire the rifle without moving it. This is done through proper trigger control. You’ve probably heard a lot of words about trigger control — “surprise break”, “snatch”, “pull”, “squeeze”… well we teach one thing here: “smooth”. No matter the speed at which I engage the trigger, it’s always going to be smooth. Imagine trying to pull the trigger straight through the rear of the buttstock, holding it to the rear while the gun recoils. It’s important to constantly engage the trigger, never letting your trigger finger disengage from the trigger while firing. This is achieved through natural trigger finger placement.
