The Yankee Hill Machine Nielson Booster Assembly is a recoil-reducing addition for suppressors using a 1 3/8”-24 thread pattern. A lot of folks around here running suppressed handguns – whether it’s for home defense, USPSA at the Nashville Gun Club, or just target practice – find these really help manage the increased backpressure when a suppressor’s attached.
How it Works
This assembly replaces the direct thread adapter on your YHM sound suppressor or other suppressor that uses the 1 3/8”-24 standard. It’s intended for use with handguns and barrels that rely on a Nielsen Piston spring to function correctly. Basically, it redirects some of the expanding gasses upward, counteracting muzzle rise and improving cycling, particularly on 9mm and .22LR platforms.
