This Gemtech muzzle brake (brand part no. 12161) is sized for .308/7.62 NATO and threaded in the metric M15x1 pattern, built with Gemtech’s QuickMount lugs so a compatible Gemtech suppressor can lock on and off quickly.

Frequently Asked Questions

Why is this threaded M15x1 instead of a standard imperial thread? Some host barrels, especially certain European or metric-threaded rifles, use the M15x1 pattern instead of 5/8×24 or 1/2×28 — confirm your barrel’s thread before ordering.

Is this muzzle brake itself an NFA item? No. It’s an ordinary Title I muzzle device; only the suppressor that mounts to it is the NFA-regulated item.
