The Land Warfare Resources Corporation’s PSD 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 PSD is a smaller version of the standard M6A2 and for close quarters combat.
It uses a short-stroke gas-piston. 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.
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.
Other features include 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 trademark 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 PSD for law enforcement or military and home defense.
