Description
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!
Our Rosco 5.56 (NATO) barrels are designed to meet the modern day carbine shooters requirements. We are a long way from our 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 we have incorporated your needs into our engineering. We have successfully accomplished this by picking the right twist rates, gas port diameters, and barrel materials according to the barrel we are making (not a lazy blanket method). We have also balanced input from our consumers and military end users in order to bring you the rifle barrels you need, not just the one we want to sell you.
