The Lancer Viper Brake is a "tunable" muzzle device that acts as both a brake and compensator to help control recoil and muzzle rise. Designed with a blast chamber and four tunable jets to effectively reduce barrel movement and allow for faster follow up shots. The brake comes with different sized jets so the operator can tune the downward force. The angled blast baffles help reduce recoil. Made from stainless steel and coated with black nitrite. Includes a crush washer and twelve tuning jets.
