Rosco Purebred Barrel AR-15 300 AAC Blackout 10.5 Pistol Length Gas Port Heavy Contour 1 in 7 Twist Stainless Steel

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-15’s, D-BAL (series), or any laser aiming devices comfortably. All NFA rules apply
