Bloodline 11.5″ M4 5.56 NATO: This Rosco 11.5″ M4 5.56 NATO Bloodline Barrel is designed to be the perfect addition to any SBR or Pistol build. ALL NFA RULES APPLY!

This Rosco Bloodline 5.56 NATO 11.5″ M4 Carbine barrel is designed to meet the modern day carbine shooters requirements. Rosco barrels are a long way from your daddy’s “Sporter” AR, and those specs just won’t cut it anymore. From properly managed dwell times for SBR’s, to running suppressed, or setting up a balanced patrol carbine they have incorporated your needs into their engineering. Rosco Manufacturing has accomplished this by picking the right twist rates, gas port diameters, and barrel materials according to the barrel they are making (not a lazy blanket method). Rosco has balanced input from consumers and military end users in order to bring you the product you need.
