Rosco Manufacturing Bloodline 10.5″ 5.56 M4 1:7 Twist Black Nitride Cabine Barrel

Bloodline 10.5″ M4 5.56 NATO: This Rosco 10.5″ M4 5.56 NATO Bloodline Barrel is designed to be the perfect addition to any SBR or Pistol build. ALL NFA RULES APPLY!

Our Rosco 5.56 (NATO) barrels are designed to meet the modern-day carbine shooter’s requirements. We are far from our daddy’s “Sporter” AR, and those specs won’t cut it anymore. From properly managed dwell times for SBRs, to running suppressed, or setting up a balanced patrol carbine, we have incorporated your needs into our engineering. We have accomplished this by picking the correct twist rates, gas port diameters, and barrel materials according to the barrel we make (not a lazy blanket method). We have also balanced input from our consumers and military end users to bring you the product you need, not just the one we want to sell you.
