Staccato C2 Cerberus Compensator Thumb Rest Mk2

The Underworld Arms Cerberus Compensator for the Staccato C2 is a compact triple port frame mounted compensator with superb efficiency and performance.  

The Cerberus uses concave gas diverters at the front wall of the expansion chamber to route gas into the two upward angled side ports and the top port. By using this concave diverter the gas retains more of its energy as it is redirected and more gas is trapped and redirected into the ports. The side ports are angled up at 68 degrees which creates a 44 degree arc of gas venting. 

The result of these design elements is an increase in recoil reduction and muzzle flip reduction for an even softer shooting experience than our cyclops compensator. 

This 50 state legal compensator is made for unthreaded barrels. The Cerberus is available anodized black or cerakote DLC grey. 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.

Pistols made between 2025-2026 have slightly different frame rails than the previous years and require a modified compensator lower. 

This compensator will usually not require recoil spring tuning. 

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. 

Everything you will need for the install is included: locking block, screws, Blue Vibratite 121 thread locker, and an allen key. An installation video is in the image gallery.
