The ZEV Technologies compensator was designed to provide superior recoil mitigation and muzzle rise reduction. The stylish and lightweight design matches the profile of all ZEV signature slides, making it the perfect addition to your build. The innovative mounting system allows for quick, secure installation and easy removal without the need for set screws, locking compound, or special barrels. It is precision machined from 7075 billet aluminum with a hard coat anodized finish. The PRO compensator was designed specifically for the G19 (But will work on any 9mm Glock) with a threaded barrel. This model has a black finish.
