Kinetic Development Group SMX6 Features The SMX6 is essential when using a KDG Stribog Receiver Extension (SRX6) as it directs muzzle blast forward away from the user s support hand during firing. This significantly enhances safety especially when shooting with extended rails. Its 6-inch length perfectly matches the SRX6 rail maintaining a balanced and uniform profile along the firearm s front end. Built from C1018 mild steel the SMX6 is durable yet easy to modify for compliance needs. It threads directly onto barrels with standard 1/2x28 threading making installation quick and tool-free. The knurled surface adds both grip and a rugged aesthetic improving handling during attachment and removal.
