The Ronin Competition 18-inch Rifle Kit from Davidson Defense is a high-performance build, optimized for precision shooting on the AR-15 platform. Chambered in 6MM ARC, this full build kit features an 18-inch barrel made from durable 4150 CrMoV steel with a nitride finish, ensuring longevity and resistance to wear. The barrel twist rate of 1:7.5 provides excellent stabilization for a range of projectile weights, while the rifle-length gas system delivers reliable cycling.
The kit includes a freefloat M-Lok compatible handguard crafted from lightweight 6061-T6 aluminum, providing ample space for accessories without adding unnecessary weight. The upper receiver, also made from 6061-T6 billet aluminum, features a Type III hard coat anodized finish for added durability. Complete with a 9310 alloy steel bolt carrier group and a 3 oz buffer weight, this rifle is engineered for optimal performance. Included are essential components such as a Mil-Spec heavy-duty buffer tube, AR-15 M4 charging handle, and an AR-15 TPI GI birdcage flash hider, making it a comprehensive kit for any gunsmith.
