The Benign Muzzle Thumper – 5.56 Compensator

Originally created as a joke for a Crye Precision charity auction build (back when zombies were still underground), the Muzzle Thumper unexpectedly stole the show at SHOT. What began as a last-minute idea turned into the most talked-about feature of the rifle.

The Benign is a tamer, purpose-driven version of the original — designed to reduce felt recoil and muzzle movement, while keeping the spirit of the OG alive.

• Threaded 1/2-28 RH

• Optimized for 5.56 and smaller bores

• Includes crush washer

• Machined with precision, finished with attitude

Whether you’re chasing performance or just love a good origin story, the Benign Muzzle Thumper delivers both.
