Rosco OPMOD Bloodline 5.56mm Nato 13.9in Threaded Barrel

Rosco OPMOD Bloodline 5.56mm Nato 13.9in Threaded Barrel

This 13.9in M4 5.56 NATO Mid-Length barrel was designed around the USASOC specs for an Improved Upper Receiver Group with a little bit of the Rosco touch as well. The longer gas system allows for a smoother gas curve which leads to managed dwell times. This combo creates a great balance of speed and performance. ALL NFA RULES APPLY! Their Rosco 5.56 (NATO) barrels are designed to meet the modern day carbine shooters requirements. They are a long way from their daddys Sporter AR, and those specs just wont cut it anymore. From properly managed dwell times for SBRs, to running Suppressed, or setting up a balanced patrol carbine they have incorporated your needs into their engineering. They have successfully 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). They have also balanced input from their consumers and military end users in order to bring you the product you need, not just the one they want to sell you.
