Yankee Hill Machine Nielsen Piston 9mm M13.5×1 LH, Stainless
1 in stock
Description
The Yankee Hill Machine Nielsen Piston is a 9mm suppressor piston threaded M13.5x1 LH, machined for use with the YHM-2055 booster housing and other common pistol suppressor boosters. Its spring-driven design lets the suppressor briefly decouple from the barrel under recoil, which keeps tilting-barrel handguns cycling reliably with a can mounted. Shooters running a 9mm suppressor on a host with M13.5x1 LH muzzle threads will find this the correct piece to make that pairing work.
Ten adjustment points give room to index the suppressor and tune alignment, helping hold point of impact consistent between mounts. Heat-treated 17-4 stainless steel handles the repeated hammering a booster piston takes. This piston is not compatible with Sidewinder suppressors.
