The Rosco Bloodline 10.5" M4 Carbine AR-15 barrel is built for modern 5.56mm NATO carbine setups, including SBR and pistol builds where dwell time and suppressed performance matter. With a 1-7 twist and nitride finish, it’s designed to run reliably while matching the common .750 inch gas block journal size used on M4-style builds.
