Overview
The KDG SMX3 threads directly onto the 1/2x28 muzzle of a 9mm Grand Power Stribog and extends the blast exit three inches forward. That puts the muzzle beyond the front of a KDG SRX3 or SRX3.25 receiver extension when the gun is fired without a suppressor, preventing the rail from surrounding an unprotected recessed muzzle.
KDG machines the four-ounce extension from C1018 mild steel, applies a black-nitride finish, and knurls the fore-end for installation. The SMX3 is a complete muzzle device, not an adapter: the barrel thread terminates inside it, and its forward end is an open 9mm bore with no output thread, QD mount, or suppressor interface. Use it only with SRX3 or SRX3.25. It is too short for SRX6 and must never be stacked with another muzzle device or suppressor.
