Product Description

The SilencerCo AC626 piston is a heat-treated 17-4 stainless steel piston designed for multi-caliber handgun suppressor setups where a Nielsen device (booster) is used for reliable semi-automatic cycling. Built for easy interchangeability, it allows you to swap pistons to match different host firearms or thread patterns, helping you use the same suppressor across multiple compatible hosts. This XL-length piston features M13.5x1 left-hand (LH) threads to provide additional clearance/length where required between the threaded barrel and the suppressor, and it is compatible with the Octane, Osprey, Omega K, and Hybrid 46 series.

  • Heat-treated 17-4 stainless steel construction for durability in suppressed pistol use

  • Designed to be quickly interchangeable to support different host firearms and calibers
  • Part of the Nielsen device/booster system that helps enable semi-auto cycling on tilt-barrel pistols
