Rosco Manufacturing

Overview

The Rosco Manufacturing Bloodline Barrel is a 10.5-inch barrel designed specifically for 9mm builds, featuring a 1:10 twist rate which helps stabilize projectiles for effective accuracy at varying distances. Its blowback gas system is ideal for reliable cycling in pistol-caliber carbines, while the 1/2x28 thread pitch allows for easy attachment of muzzle devices. This barrel is commonly found in compact AR-15 builds that prioritize maneuverability and performance in close-quarters situations.
