The Yankee Hill Machine Nielsen Piston (brand part no. YHM-2062-28) is a recoil-booster piston built to work with YHM’s own booster housing YHM-2055 as well as many other popular pistol suppressors, threaded here to .578×28 for a 9mm host. YHM machines it from heat-treated 17-4 stainless steel for maximum durability and corrosion resistance, and builds in 10 individual adjustment points so a shooter can zero out any impact shift the piston introduces at the muzzle. Yankee Hill offers this Nielsen piston in a variety of thread patterns to fit most 9mm suppressor hosts, and at just 1.4 ounces it adds minimal weight to the front of the gun. It is not compatible with Sidewinder suppressors, so confirm your can before ordering.
