The Underworld Arms Cyclops Compensator for the Tisas B9R Carry 4.25" 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 compensator is made for the first generation B9R with bushing style barrel.
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 for a cohesive aesthetic. The holster we make for the MAC is compatible with this thumb ledge lower.
On most builds this compensator will not require recoil spring tuning but we offer a spring tuning kit if your build requires it.
This compensator increases the dimensions of the firearm so it requires a dedicated holster such as the ones we make, or a universal holster such as the MSP Tier 1, and the blackhawk omnivore light bearing.
