OPS Inc

Since 1988 OPS INC has been one of the primary suppliers of suppressors to the U.S. Military.
The entire product line of OPS INC is designed for the unique requirements of the U.S. Military. All of company's suppressors are self cleaning and maintenance free, and can be attached and removed without the use of any tools. The patented design of the devices raises the normally low frequency blast sound to a primary ultra high sound pitch.
5.56/.22 caliber models include muzzle brake kit: muzzle brake, barrel fitting, thread protector, and crush washer. The 12th model 7.62/.30 caliber includes the muzzle brake and thread protector.
OPS Inc. muzzle brakes provide maximum recoil reduction with reduced muzzle blast. Originally developed for the military, the OPS Muzzle Brake is the result of extensive research into muzzle gases and the effects of redirecting them for recoil reduction and accuracy enhancement.
