LANCER SYSTEMS 6.5 Creedmoor Viper Muzzle Brake 5/8-24 UNEF SS

The Lancer Viper Brake is a tuneable muzzle brake and compensator designed for precision shooters. Engineered with a blast chamber and four tuneable jets, the Viper muzzle brake effectively reduces barrel movement and felt recoil, making for faster follow on shots and a more accurate shooting experience. Features: Angled blast baffles reduce recoil and stabilize the rifle Four jet locations on the top of the brake redirect gas pressure from the blast chamber creating a downward force on the muzzle Different size jets are supplied so the operator can tune the desired amount downward compensation Includes: Locking jam nut Wrench Adjustable tuning jets Specs: For caliber 6.5 Creedmoor Made from Stainless Steel Finish: Polished Length: 3.75″ Width: 1.87″ (at the widest point) Height: 1.05″ Weight: 0.75 lbs Tuning Procedure: The objective when tuning your Viper is to minimize muzzle movement when shooting rapid strings of fire from an offhand position. Do not attempt to tune your muzzle brake compensator from a bench or from a supported position. Do not adjust or replace the compensator jets without first checking to make sure that the firearm has been cleared of all ammunition. To begin tuning, set up at close range of 25-50 yards from a paper target. Fire a rapid group of 3-5 rounds. If the group patterns in an upwards direction, increase the amount of gas being ported through the jets by replacing one or both with a larger orifice size. If the group strings down, decrease the gas being ported upwards be replacing one or both of the jets with a smaller orifice. Torque both jets to 8-10 in/lbs and fire the shot string again. Repeat this process until your group stops stringing up or down and holds at the same level of elevation. Overall group size should improve markedly when rapidly shooting offhand with a properly tuned Viper installed. MADE IN THE USA
