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