The Land Warfare Resources Corporation’s M6A3 is a select-fire tactical rifle chambered in 5.56 NATO and 6.8mm Rem. SPC. LWRC, founded in 1999, specializes in making AR15- and M16-style rifles, but with a handful of trademark features. The M6A3 is similar to the standard model, but unlike the standard it was designed for precision shooting.
The M6A3 has a mid-length short-stroke gas-piston, which functions the same way as the standard, but the mid-length is supposed to reduce recoil. It operates by propellant gases cycling from the barrel into a tube and then they’re directed onto a piston, which drives the bolt back. Since gas isn’t entering the bolt directly, carbon buildup is reduced in turn the bolt requires less maintenance. The bolt was treated with a proprietary nickel coating that makes the action corrosion resistant and adds a permanent lubrication, which increases functionality in wet or sandy conditions. Lastly, the M6A3 has an adjustable gas system that allows shooters to regulate gas pressure for different cartridges, weather conditions or tactical situation.
Features include a cold hammer forged barrel, so a machine carefully carved the grooves in the bore. This process improves the rifling’s durability. The barrel itself was treated with NiCorr, which is often compared to chrome, but unlike chrome it applies evenly. NiCorr treatment makes the barrel wear and corrosion resistant, and adds lubricity and durability. It has an adjustable stock, a target crown that helps maintain barrel harmonics so when a round is fired the barrel’s vibrations won’t throw off the projectile’s trajectory, an ergonomically friendly Magpul grip, adjustable BUIS sights and Picatinny rails for easy mounting of optics or accessories.
An optional feature is Cerakote ceramic finish instead of a black anodized finish. It adds the corrosion resistance of Teflon, but is supposed to be more durable (add $150).
LWRC recommends the M6A3 for snipers in law enforcement or military, but also for competitive shooting.
