Kinetic Development Group SMX3 3" Muzzle Extension 1/2x28 Black Nitride - Fits Stribog SP9 w/ SRX3/SRX6

The Kinetic Development Group SMX3 is a 3-inch muzzle extension machined from C1018 steel with a Black Nitride finish, purpose-built to extend the barrel of the Stribog SP9 pistol past the end of an attached KDG SRX3 or SRX6 rail extension.

The SMX3 threads directly onto the factory barrel using the standard 1/2x28 thread pitch, adding a clean 3 inches of reach so the muzzle and any attached device clear the front of the SRX-series rail and the M-LOK accessories mounted to it. The result is safer handling with the muzzle extending beyond the shooter's support hand and a clean, matched aesthetic alongside the SRX rail extension.

Constructed from C1018 mild steel and finished in Black Nitride for corrosion resistance, the SMX3 installs without permanent modification and is offered here in the 3-inch configuration. A longer 6-inch SMX6 variant is also available from Kinetic Development Group for users wanting additional reach.
