The Rosco 10.5 inch Barrel, designed for the 300 Blackout, is optimized for use in short-barreled rifles (SBR) or pistols, especially when paired with suppressors. This precision-engineered barrel serves as a direct replacement for MK 18 platforms originally chambered in 5.56 NATO. Its design caterers to carbines that require extended rails to accommodate laser aiming devices like the PEQ-15 and D-BAL series with ease.
