Prodigy 4.25" Basilisk Compensator Thumb Rest Mk2

The Underworld Arms Basilisk Compensator fits both the Prodigy 4.25 and Prodigy 4.25 Comp. It is a frame mounted compensator with two large expansion chambers that redirect the gas flow into two large top ports and four angled side ports which dramatically reduces muzzle flip and felt recoil. 

This 50 state legal compensator is made for unthreaded barrels. The Basilisk is available anodized black or cerakote coyote brown. 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. 

On some builds recoil spring tuning may be required. The stock recoil spring is 12lbs, with this compensator a spring in the 9-11lbs range may be necessary for reliable cycling. 

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 Tac-Rig (these have the most features and highest quality construction), or a universal holster such as the MSP Tier 1, and the blackhawk omnivore light bearing.
