The Rosco 5.56 (NATO) barrels are designed to meet the modern day carbine shooters requirements. We are a long way from our daddyā€™s ā€�Sporterā€¯ AR, and those specs just wonā€™t cut it anymore. From properly managed dwell times for SBRā€™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 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.
