This Gemtech muzzle brake (brand part no. 12156) is sized for .308/7.62 NATO and threaded 1/2-28, built with Gemtech’s QuickMount lugs so a compatible Gemtech suppressor can lock on and off quickly.

Frequently Asked Questions

How is this different from the 5/8×28 QuickMount 7.62 brake? This version is threaded 1/2-28 rather than 5/8×28 — match the thread pitch to your barrel’s muzzle threading.

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.
