Ultradyne USA Mercury Compensator 5/8x24 7.62 – AR-10 & .308 Rifles

The Ultradyne Mercury Compensator reduces muzzle rise and felt recoil on .308/7.62 rifles, keeping you on target for faster follow-up shots. Its directional port design vents gases upward and to the sides, countering muzzle climb without excessive concussion to the shooter. Machined from heat-treated steel with a salt bath nitride finish, this compensator is built to handle high round counts and maintain zero under sustained fire.

Installation requires a 5/8x24 threaded barrel and an armorer's wrench or crush washer for proper timing. Compatible with AR-10 platform rifles and bolt-action .308 rifles with matching threads. The compact profile adds minimal length while delivering measurable recoil management. Crush washer not included; timing shims or Rocksett recommended for permanent installation.
