Product Description
The Rosco Manufacturing Bloodline 16" 5.56 NATO Heavy Barrel is built for shooters who run their rifles hard and demand durability and consistency. Made from 4150 Chrome Moly Vanadium (CMV) steel and treated with a protective nitride finish, this heavy-profile AR-15 barrel is designed to handle sustained fire and hard use.
With a 1:7 twist rate for stabilizing a wide range of modern 5.56 projectiles, a carbine-length gas system, and standard 1/2x28 muzzle threads, it’s a reliable foundation for duty, range, and training carbines.
