  • .750″ gas block journal fits compatible AR-15 gas blocks

The Rosco Bloodline 16″ 5.56 Heavy Barrel is built around a substantial contour for shooters who prioritize rigidity and heat capacity over minimum barrel weight. Its carbine-length gas system, 1:7 twist, and 5.56 NATO chamber keep the operating setup familiar, while the nitride-treated barrel and extension provide a durable finish for regular use.
