This Rosco 10.5" 300 Blackout barrel was designed for SBR and Pistol use in conjunction with suppressors. The 10.5" 300 Blackout Rosco barrel was made to be a direct 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.
