MAC 9 DS 5" Gen 3 Cyclops Compensator Thumb Rest Mk2

The Underworld Arms Cyclops Compensator for the Military Armament Corp 5" MAC 9 DS 1911, is a frame mounted compensator with a large expansion chamber that redirects the gas into a single top port that is similar in size to the Staccato XC and Sand Hawk.

This 50 state legal compensator is made for unthreaded barrels and is anodized black. This compensator has an ambi thumb ledge lower with horizontal serrations that match the horizontal serrations on the slide release and thumb safety, which creates a cohesive aesthetic.

We designed our thumb ledge lower around the X300, other brands of lights have longer mounts and will sit farther forward. 

Adding a compensator to a pistol reduces muzzle flip and recoil energy, as a result recoil spring tuning may be required and we offer a spring set for this purpose. 

Compatible holsters are available HERE

This compensator increases the dimensions of the firearm so it requires a dedicated holster like the ones we make or a universal holster such as the MSP Tier 1, or the blackhawk omnivore light bearing.
