From the manufacturer
The Rosco 5.56 barrels are designed to meet the modern-day carbine shooters requirements. Rosco Manufacturing is a long way from your 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 they have incorporated your needs into our engineering. Rosco has 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 our consumers and military end users to bring you the product you need, not just the Mfg: Rosco Manufacturing
