Maximize your velocity scaling, terminal accuracy, and medium-range tracking consistency across standard AR platforms. The P2A PATRIOT 18" 5.56 NATO Mid Length M-LOK Rifle is a premium, fully assembled firearm system meticulously engineered to balance short-range maneuvering with extended-distance precision. Built around a matching set of forged 7075-T6 aluminum receivers with standard right-side ejection configuration tolerances, this system centers on an 18-inch medium-contour barrel. The highly versatile 1:8 twist rate is optimized to stabilize a massive cross-section of standard projectiles, spanning affordable 55gr plinking grains up to heavy 77gr match ammunition. A tuned direct impingement mid-length gas setup ensures a comfortable, uniform cycling stroke with lessened component friction, while an extended 15-inch free-float aluminum handguard wraps the barrel to supply structural rigidity and massive modular M-LOK real estate for tactical gear.
