The Ronin Competition w/SBA5 Brace is a precision-engineered 7.5-inch pistol build kit designed for the discerning gunsmith who values freedom and performance. Chambered in 5.56x45mm NATO, the 416R stainless steel barrel features a 1:7 twist rate, perfect for stabilizing a wide range of projectiles. The barrel’s government profile and precision-threaded 1/2x28 muzzle allow for the included AR-15 birdcage flash hider.
The kit includes a strong, lightweight aluminum M-Lok handguard, providing versatile mounting options while maintaining a sleek black finish. Built upon a Black Diamond Series AR-15 billet upper receiver made from 6061-T6 aluminum and treated with Type III hard coat anodization, this kit ensures durability. The SBA5 pistol stabilizing brace, constructed from nylon reinforced polymer, integrates seamlessly for enhanced stability. Accompanied by a nitride-finished 9310 alloy steel bolt carrier and mil-spec charging handle, this full build kit is engineered for performance and reliability.
