Rosco Bloodline AR-15 300 Blackout 7.5" Nitride Threaded Barrel

Rosco Bloodline Barrel Features The Rosco Manufacturing Bloodline Barrel is machined from chrome moly vanadium steel and finished with a nitride coating a combination chosen for its wear resistance and ability to handle sustained heat under suppressed fire. At 7.5 inches it represents the shortest barrel length Rosco offers for the .300 AAC Blackout cartridge purpose built for compact SBR and pistol builds running a suppressor. The 1 in 5 inch twist rate is optimized to stabilize the heavier subsonic projectiles that the .300 Blackout platform is often built around. A 5/8x24 thread pattern allows direct mounting of a suppressor or muzzle device without an adapter. Weighing 17.23 ounces the barrel keeps a short suppressor ready build light and maneuverable an important factor in a personal defense weapon configuration. Rosco designed this barrel specifically to balance the flexibility of an ultra short PDW style build against the ballistic performance shooters expect from the .300 Blackout round. The nitride finish also simplifies cleaning and maintenance compared to a standard phosphate coating helping the barrel hold up to repeated suppressed range sessions. This barrel is a strong option for builders assembling a compact suppressor focused AR platform without compromising reliability.
