The Lancer Viper Brake .308 Black is a tunable muzzle brake and compensator built for precision shooters running .308 Winchester and other .30-caliber rifles. It threads onto 5/8-24 muzzles and pairs recoil reduction with adjustable downward compensation, so the rifle stays flatter through the shot and settles faster for follow-on rounds. Shooters who run gas-operated .308 platforms and bolt guns alike use this brake to keep the reticle on target during a string of fire. It lives in our muzzle brake lineup as a serious option for anyone chasing tighter groups and quicker shot recovery.
The Viper Brake works through a blast chamber feeding four tunable jets, with angled blast baffles that redirect gas to cut felt recoil and stabilize the rifle. Four jet locations route gas pressure to apply downward force at the muzzle, countering rise. The package includes six configurable tuning jets, letting the shooter dial in the exact amount of downward compensation for a given load and barrel. Construction is black nitrided steel, which holds up to repeated gas cutting and heat without the wear common to softer finishes. The brake measures 3.75 inches long, 1.87 inches at its widest point, and 1.05 inches tall, and ships with a locking jam nut for mounting. It carries 5/8-24 threading standard for .30-caliber rifles.
This brake earns its keep on rifles where recovery time matters, whether that's a competition stage, a precision rifle setup, or a hard-use .308 build. The tuning jets let a shooter balance recoil reduction against muzzle compensation for a specific load, which is why this device draws interest from shooters who reload and chase repeatable results. The black nitrided finish and USA-made construction back it up for long-term use. If you're outfitting a .30-caliber rifle, browse our full barrels and choke tubes selection alongside other compensator options to match the device to your platform.
It uses 5/8-24 threading, the standard pitch for .30-caliber rifles including .308 Winchester. Confirm your barrel is cut to 5/8-24 before ordering, and use the included locking jam nut to time and secure the brake at the muzzle.
The brake ships with six configurable tuning jets that fit into four jet locations. By swapping and positioning these jets, the shooter adjusts how much gas pressure gets redirected downward, tuning the amount of muzzle compensation to match a specific load and barrel for flatter shooting.
It is built from black nitrided steel, a finish chosen for its resistance to the heat and gas cutting that muzzle devices endure. The brake is made in the USA per manufacturer specifications.
Both. The blast chamber and angled baffles cut felt recoil, while the four downward-directing jet locations counter muzzle rise. The tunable jets let you balance the two effects, keeping the rifle flatter and settling faster between shots.
It works on both .30-caliber platforms. Gas-operated .308 and AR-10 pattern rifles benefit from the faster recovery, and precision bolt guns benefit from the tunable downward compensation for steadier sight pictures during a string of fire.
