IMPORTANT!!!, before adding to cart you must check your gun and select the correct frame generation from the drop down list. Gen 1 frame guns came with short iron sights, later production Gen 2 frame guns came with much taller suppressor height sights. These two generations have different frame rail dimensions so we made two different lowers that are engraved with M1 and M2. We do not make a comp for Gen 3 frame guns with full length dust cover yet.
The Underworld Arms Cyclops Compensator for the Military Armament Corp 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 a multi slot lower rail, for a single slot lower rail please see our other listing.
On most builds this compensator will not require recoil spring tuning but we offer a spring tuning kit if your build requires it.
Compatible holsters are available HERE
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.

Seems very effective but have not run enough rounds down range for a complete evaluation at present but plan to continue testing and will comment further at a later date.
This comp system is next level!!! It took my MAC 9 from meh…to amazing!!! I ordered one for my Tisas ds to get the same amazing look and functionality!!! Definitely worth every penny!!!
Work’s well but noticed the groves didn’t line up to secure compensator properly. This results in comp sliding forward after shooting. Perhaps I purchased the wrong one by mistake.
Absolutely amazing product! Works great and I feel this item is a great value at the price point. I would highly recommend and would totally buy again.
This compensator is a great fit for the firearm. It enhances both the appearance and performance, making it feel like a more expensive firearm. If you're looking to improve your firearm's performance and give it a great new look, this is an excellent choice.
