This Rosco 11.5″ M4 5.56 NATO Bloodline Barrel is designed to be the perfect addition to any SBR or Pistol build. This 11.5″ barrel is machined to a balanced Government contour, offering a solid balance between rigidity and weight. The reliable carbine-length gas system ensures your rifle gets the right amount of gas to cycle even in adverse conditions. The 5.56 NATO chamber is fully compatible with .223 Remington ammunition, with a 1:7 twist rate that is perfect for heavier, precision-oriented cartridges, but is thoroughly functional with popular and less expensive bullet weights.
