The WARRIOR X4 Tuner Brake is a new and updated version of our highly effective and successful Muzzle Brake range. The V2 TUNER NUT is bigger and heavier making tuning your rifle's loads faster and more effective. The V1 TUNER NUT is a slimmer version of the V2 but just as effective. It is based on the hugely effective Erik Cortina tuner brake but with WARRIOR muscle. It is a muzzle brake and barrel tuner in one making the fine-tuning of your loads a lot easier.
