Shop the Rosco Purebred 300 Blackout 10.50" Stainless Steel at Nautilus Arms.
This Rosco Purebred 10.5" 300 Blackout Barrel was designed for Sbr/ Pistol use in conjunction with suppressors. The 10.5 Rosco barrel was made to be a direct precision replacement for any MK 18 platforms that are currently in 5.56 Nato. The 10.5 barrel is also perfect for carbines which require a slightly longer rail in order to run PEQ-15s, D-bal (series), or any laser aiming devices comfortably.
