$145.00 $130.00

14.5” M4 5.56 NATO Bloodline Barrel (Mid-Length): This 14.5” 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.

14.5” M4 5.56 NATO Bloodline Barrel (Mid-Length): This 14.5” 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!

The 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 Rosco has 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 also balanced input from consumers and military end-users in order to bring you the product you need, not just the one they want to sell you.
