Rosco Manufacturing 16″ Slimline 5.56 NATO Bloodline Barrel (1/7 Twist)

This Rosco 16” 5.56 NATO Slimline barrel is the lightest 16″ 5.56 NATO barrel in the market without sacrificing reliability and performance. The requirements for light weight carbines has prompted us to create a barrel that will provide the end user with significant weight savings.

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.
