Designed with the competitive rifle shooter in mind, the Enhanced Stabilization Attachment fixes to the threaded muzzle of a .223 or 5.56 caliber rifle to flatten out muzzle rise and reduce felt recoil. The gas jet on top of the compensator provides downward thrust to minimize muzzle climb and help keep the shooter on target for consecutive shots.


-Less felt recoil for the shooter

-Neutralized muzzle rise created by the inline gas port on top and muzzle baffles

-Adjusted baffles reduce high pressure gas turbulence in the flight path of the bullet resulting in improved accuracy

-Eliminates negative recoil impulse

-Overall Length: 2.6”

-Diameter: .750”

-Weight (without crush washer): 2.2oz (63g), 3.4oz (98g) for Square model

-Finish: Salt Bath Nitride (QPQ) for a long lasting deep black color



Before attempting to remove your original muzzle device, consult your manufacturer or a professional gunsmith to check your barrel for a blind pin preventing the original muzzle device from being removed. Attempting to remove a muzzle device with a blind pin may cause permanent damage to your barrel.
