The SilencerCo piston is 17‑4 stainless steel, heat‑treated. It is the moving part of a Nielsen device so a semi‑auto pistol with an unlocking barrel can cycle with a suppressor mounted. Female threads mate to SilencerCo threaded barrels. This AC1346 is a .578x28 XL piston, for hosts that need extra length between the barrel threads and the suppressor. Compatible with Omega K, Hybrid 46, Hybrid 46M (with Charlie piston mount), Osprey, Octane, Omega 36M (with Charlie piston mount), and Spectre. Made in the USA.
