The YHM Nielsen piston is a threaded piston designed to work with booster housings and a variety of pistol suppressors to manage impact shift and improve consistency. It is made from heat-treated 17-4 stainless steel for corrosion resistance and durability, and it offers multiple adjustment points to fine-tune timing. This item lists M16 x 1 RH threading and is identified for use with YHM booster housing YHM-2055 and many popular pistol suppressors.
