Description

This model is also suitable for Glock 21 threaded in 16x1LH (left-hand thread) manufactured from 2017 (if in doubt have your thread checked).

The model presented includes an inertia amplifier, which avoids having to modify the barrel or change the recoil spring.

The maintenance-free valves are made of billet aeronautical alloy. Their very sophisticated profile gives them exceptional efficiency. They will give the lowest sound level with subsonic ammunition, but conventional (or supersonic) ammunition can be used continuously without damaging it.
