Boasting a patented short-stroke gas-piston operation, the LWRCI M6IC-A5 is a rugged-built rifle ready to answer the call of duty.
They say competition breeds innovation, which couldn’t be more true than it is for LWRC International (LWRCI). The company was founded to pursue the development of a short-stroke, gas-piston-operated firearm that would replace the M4 as the main service weapon for the U.S. Army.
Although the Individual Carbine competition was cancelled in 2013, that original research and development led to a whole family of LWRCI rifles that are produced under the Individual Carbine (IC) nomenclature and sold to everyone from warfighters and law enforcement to hardcore civilian shooters.
One of the latest rifles from the manufacturer is the LWRCI M6IC-A5 chambered in 5.56 NATO and available in OD Green, which, like the Incredible Hulk, is a highly evolved and technologically advanced version of a Bruce-Banner-like classic, Eugene Stoner’s AR-15/M16. As with the original Individual Carbine design, the hallmark of the A5 is LWRCI’s patented short-stroke, gas-piston operation, which is designed to improve upon the original direct gas impingement system developed by Stoner in the 1950s.
The short-stroke, gas-piston system is constructed with aerospace-grade superalloys that can withstand extremely high temperatures without losing their strength or becoming fatigued. This makes the LWRCI M6IC-A5 highly reliable even in the worst conditions. Because the A5 is duty built for tip-of-the-spear military personnel around the world, durability and functionality are non-negotiable.

Piston Driven
One of the known issues with the direct gas-impingement system developed by Stoner is that hot gases and carbon from the discharged cartridge are dumped into the action of the rifle where they strike the gas key, pushing the bolt carrier rearward against the buffer spring and thus cycling the action. This causes carbon buildup in the action and eventually contributes to functionality issues. If nothing else, this necessitates more regular weapon cleaning.
The beauty of the short-stroke, gas-piston operating system, however, is that gases from the spent cartridge move through the gas block where they strike a piston—the piston then drives the bolt carrier rearward while the dirty gases exit the firearm clear of the action itself. Combined with LWRCI’s nickel-boron coating and the superalloy components used in the piston system, this means the action stays cleaner, longer, thus reducing carbon buildup that leads to malfunction.
The tradeoff, of course, is that piston-operated platforms typically cost more than their direct gas-impingement counterparts. Some have pointed out that the piston system increases felt recoil, but the difference is negligible, especially with the 5.56 NATO/.223 Rem. cartridge.
For some people the increase in cost is worth it, particularly when the mission profile includes the discharge of high volumes of ammunition and minimal time for cleaning. For the warfighter, reliability is obviously paramount, and the cost is often negligible in comparison to the value gained. For the weekend shooter, the cost may not be necessary but could nonetheless be desirable.

Historically, the other problem has been the way in which the piston operating system has been applied to the AR platform. Early on, several manufacturers tried to take Stoner’s design and modify it for use with a piston system, but without considering the effects this would have on components that weren’t designed for that purpose. Ultimately this led to issues like carrier tilt and damage to the lower receiver.
What LWRCI and others have done, however, is engineer the AR concept and components specifically for use with a short-stroke, gas-piston operating system. Rather than being an afterthought, the short-stroke piston operation is foundational to the LWRCI M6IC-A5.
The AR Evolved
Among the standout features on the new A5 is a machined Monoforge upper receiver with an integrated rail base that is lighter and stronger than previous two-piece designs. The rail comes pre-drilled for a host of rail segment configurations to meet the user’s needs and preferences, including the option to install a quad rail via the retaining screw holes.
The upper also eliminates the need for a standard barrel nut, and instead is secured by a proprietary non-indexing torque ring. This ring system provides even pressure around the barrel for optimal fit. Not only is the upper and rail design functional, it’s also visually appealing. Available Cerakote finishes include Flat Dark Earth (FDE), Olive Drab Green (ODG) and Patriot Brown (PBC), and then of course as Henry Ford always said, there’s black.

LWRCI prides itself on providing the customer with top-tier quality parts in its firearms, according to Jeff Clemmer, vice president of product development, which is why it manufactures its cold hammer-forged barrels in house. The barrels are forged from 41V45 steel alloy and are treated with NiCorr surface conversion technology, which the company claims is more resistant to wear, heat and corrosion than hard chrome.
The LWRCI M6IC-A5 features eye-catching spiral fluting to provide a barrel that’s 20 percent lighter than those of similar diameter. The barrel is pretty damn sleek to look at, but the spiral fluting also allows the barrel to cool faster and, according to LWRCI, provides greater accuracy. Featuring a scallop-cut design on the front of the handguard, the A5 also has an easy-to-access, two-position gas block for use with or without a suppressor and includes a standard A2-style flash hider.
As a duty-built rifle, the LWRCI M6IC-A5 is fully ambidextrous, allowing the shooter to manipulate the firearm from a number of different positions and/or around, over or under barriers. This includes ambidextrous safety selector, charging handle and mag release.
The bolt and carrier group feature LWRCI’s patented nickel-alloy coating, as does the trigger unit. The nickel-alloy coating, according to the company, provides a permanently lubricated surface that never rubs off or attracts debris. Two barrel length options are available, either a 14.7- or 16.1-inch configuration, with not even half a pound of weight difference between the two. The rifle tested was the 16-inch version.
Range Tested
Accuracy testing was conducted at 100 yards from a bench with a Steiner M5Xi 3-15x50mm Military optic, while close-range target work was performed with EOTech’s HHS II EXPS2-2 with G33.STS magnifier. Velocity was measured with a Competition Electronics ProChrono chronograph from Brownells.
The first load tested was the Nosler Custom 69-grain Match Grade, which posted an average velocity of 2,507 feet per second (fps), a standard deviation of 15 fps and an extreme spread of 27 fps. The best group of the accuracy testing came with the Nosler Custom, which produced an uber-impressive group of just .254 inch. The average group was 1.28 inches.

The second load tested was Hornady’s 55-grain V-MAX, which is quite typically a top performer. The 55-grain V-MAX posted a miniscule best group of .361 inch and an average group of .80 inch. The average velocity was 2,793 fps, with a standard deviation of 27 fps and an extreme spread of 49 fps.
Third and finally, HPR’s 62-grain Black Ops was tested. Packaged to perfection, the Black Ops load produced a best group of 1.38 inches and an average of 1.67 inches. The average velocity was 2,694 fps, with an extreme spread of 32 fps and a standard deviation of 21 fps.
Parting Shots
One of the main advantages with the LWRCI M6IC-A5 is that you get a highly-advanced, highly-functional, short-stroke, gas-piston operated AR right out of the box for $2,749 (MSRP). Sure, you could make similar upgrades yourself, but let’s face it — not everybody wants a do-it-yourself AR build. Even then, very few DIY builds would rival the A5.
The A5 also comes fully loaded with Magpul pistol grip and magazines, as well as a nickel-boron coating on the trigger, bolt carrier and group, and barrel. Flip-up sights come standard, while a continuous top rail provides a great number of day and night optic configurations. The rifle is also fully ambidextrous, incredibly ergonomic in design and functional to operate. Color options match an already sleek design, and you know you’re getting an aerospace-grade gun with unsurpassed longevity.

The Remington New Mexico AR from Remington’s Law Enforcement division is a capable rifle that can meet a variety of needs.
For deer- and hog-sized game, I find solid bullets between 62 and 79 grains work best. But these heavier, longer bullets require barrels with a twist rate of 1:7—not the 1:8 and 1:9 that tend to be the norm—needing the faster twist rate to stabilize. You can fire these stouter bullets in barrels with 1:8 and 1:9 twist rates, but they are less accurate; in some cases, I’ve had these bullets tumble in flight, leaving keyholes in paper targets.
Ready to Hunt
It rained over half the time, and the Mississippi Delta was a regular mud fest. So I hunted with a wet and muddy rifle more often than not, and that provided a good, if unintended, field test for the hard-coat black anodized finish on the receivers and the barrel’s manganese phosphate parkerized finish. Wet or muddy, all the New Mexico required was a quick wipe down and it was ready to go. I found no rust anywhere on the outside of the rifle, even after being home a couple weeks and (having forgotten to care for the rifle) finding it in a gun case with dried mud splattered from flash hider to the front half of the handguard.
At the Range
From beginning to end, accuracy was outstanding, and I was most impressed with the last two groups with the Hornady Full Boar. By this point, I had fired over 120 rounds through a barrel that hadn’t been cleaned by me, ever. The barrel itself was hot enough to blister the skin. I was nearly two hours into the evaluation, so I wasn’t at my sharpest, either. And the very last five-shoot groups were still right around 1 inch. That’s some accuracy from a semi-automatic rifle with a 16-inch barrel.
LE Roots, All-Around Versatility
The 1:7 barrel twist, Eaves noted, is the current Mil-Spec for U.S. military AR carbines. Of course, military specifications have changed over the years. During the Vietnam War, the Mil-Spec barrel twist for the 16 was 1:12. As the services went to larger, heavier bullets, that twist rate changed, and currently, Mil-Spec barrel twist rate is, you guessed it, 1:7.
An Improved AR
Speaking of handguards, another change Springfield Armory has implemented with the SAINT is to use furniture from Bravo Company Manufacturing instead of the typical GI-style furniture found on most entry-level guns. The handguard on the SAINT is Bravo Company’s new PKMT Handguard, a slim-profile, polymer handguard with KeyMod attachment points. This handguard was developed and produced exclusively for the SAINT, but was slated to become available as one of Bravo Company’s aftermarket accessories a little while after the 2017 SHOT Show.
The receivers on the new Springfield Armory SAINT are both type III hard-anodized aircraft-grade 7075 T6 aluminum. The flat top upper receiver comes equipped with a forward assist and M4 feed ramps, while the lower features Springfield Armory’s proprietary Accu-Tite Tension System, which consists of a nylon-tipped tension set screw that tightens the fit between upper and lower to remove any play that might exist. The SAINT also has an M16 bolt carrier group with a Carpenter 158 steel shot-peened and magnetic particle inspected bolt for more reliable function and a properly staked gas key.
Potent and Practical Defender
A while after the event, Springfield sent me a sample of the SAINT for review. The SAINT ran flawlessly during my time in Vegas with it, so I was pretty sure it would do so again in my independent testing, but I did want to see what kind of accuracy it was capable of producing, something I was not able to do at the event itself.
In my testing, I used five different loads to gauge performance, all .223 Remington loads: HPR’s 55-grain FMJ, Hornady’s new American Gunner 55-grain HP and BLACK 62-grain FMJ, Aguila Ammunition’s 55-grain FMJ and SIG Sauer’s Elite Performance 77-grain OTM Match. I measured velocities with a Competition Electronics ProChrono Chronograph from Brownells placed about 10 feet from the muzzle. Accuracy data was produced from three, five-shot groups taken at 100 yards from a Caldwell Matrix shooting rest, also from Brownells.
Overall, the SAINT’s accuracy was about what I anticipated. It wasn’t stunningly accurate, but it was plenty capable for a defensive carbine — accuracy that I’d feel comfortable with in a defensive scenario at close to intermediate ranges.

When the latch is pulled backwards and down, the barrel and cylinder pivot down, and at the same time, the ejector is raised away from the cylinder, ejecting the cartridges. Continuing to rotate the barrel down allows the ejector to snap back into the cylinder, allowing fresh cartridges to be inserted. Once loaded, the barrel can be pushed up and locked into place. When doing so, the shooter must pay attention that, for safety reasons, an empty chamber rests and is locked in place beneath the hammer. That may require cocking the hammer and while restraining it, allowing it to go forward on an empty chamber.
The walnut grip panels, or stocks, on the test gun were nicely executed with a dull, oil type finish, which afforded a solid grip while shooting. The trigger broke cleanly at a little more than 4 pounds after some slight creep. The fluted cylinder held six rounds of .38 Special, but the gun is also available in .45 Colt, .44 Russian and .44-40.
