The Mad Pig Thumper muzzle brake was designed based off our extensive experience trying to balance the desire for a clean in line muzzle brake with recoil compensation. We added an inside ledge to give it some back pressure, and designed this to also accept a ½ allen drive to aid in installation. It's not a timed brake, simply screw it on to roughly 15ft/lbs. The brakes are finished in black oxide for a nice deep finish to match Henry and Marlin finish and also allow gunsmiths to hand finish them for a seamless appearance without having to try to cut through extra hard nitride. Our brakes are made to closely match the outer diameter of most of their respective models for the seamless look Mad Pig Customs made famous with our original Thumper line.
