The YHM Nielsen Piston in 45 Cal, M16x1 right-hand thread (brand part number YHM-2062-MR) is a booster piston built for YHM’s own YHM-2055 booster housing as well as many popular pistol suppressors. Machined from 17-4 stainless steel and heat treated for durability and corrosion resistance, it gives suppressor owners 10 adjustment points to zero out any impact shift caused by the host pistol. YHM builds these pistons in a range of thread patterns to fit most 45-caliber pistol hosts.
