About Rosco Manufacturing Bloodline 12.5" 5.56 M4 1:7 Twist Black Nitride Cabine Barrel - BL-125-556-M4-7-C

This 12.5″ Rosco barrel is designed to bridge the gap between SBR-Pistol and/ or RECCE platforms and delivers amazing precision performance for its compact size. It is the perfect addition for the person attempting to create the ultimate intermediate patrol platform. 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 product you need, not just the one we want to sell you.
