Description
This Rosco Purebred 10.5 in 300 Blackout Barrel was designed for SBR or pistol use in conjunction with suppressors. The 10.5 inch Rosco barrel was made to be a direct precision replacement for any MK 18 platforms that are currently in 5.56 NATO. It 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.
