The Underworld Arms Basilisk Compensator for the Springfield Prodigy 4.25" 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 a single slot lower rail, for a multi slot lower rail please see our other listing.

On some builds recoil spring tuning may be required. The stock recoil spring is 12lbs, with this compensator a spring in the 9-10lbs range may be necessary for reliable function unless high power loads are being used.

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.

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

Prodigy 4.25" Basilisk Compensator (Single Slot Rail)

The quality of machining is excellent. All parts fit perfectly and locked down securely without coming loose, thanks to the included Loctite. The black finish matches the slide of the Prodigy. I was able to achieve a really nice grouping with the Basilisk compensator paired with a V8 ported barrel. I'm running this setup with a 9lb recoil spring. Great products, fast shipping, and innovative design!

Prodigy or Pit Viper?

The quality of machining was excellent. All parts fit very nicely and locked down without coming lose with the included loctite. The black matched the slide of the Prodigy. I was able get a really nice grouping with the Basilisk compensator so much I bought the Cerberus Compensator as well, can't wait to try that out at the range as well. Great products, fast shipping, and innovative. Glad i was able to change my prodigy into a comped prodigy without having to send it off for work.
