Universal Comp

Volker Mk2 Universal Compensator is designed to be used across multiple platforms that share the same barrel threads. This comp has a minimalist design size that is no wider than the slide and therefore works with most holsters that have an open bottom. The compensator is held tight to the barrel utilizing a unique spring crush washer design that eliminates the need to use set-screws, rockset or other annoying and/or damaging retention devices.
 
Made from 416r Stainless steel and then QPQ Black Nitrided for a tough, were resistant finish that both looks good but also lasts.
