The SilencerCo AC22 Fixed Barrel Spacer replaces the booster spring inside the piston housing and locks the Nielsen device in place. That lets your SilencerCo pistol can run on a fixed-barrel host, like a 9mm carbine, a .22 pistol or a fixed-barrel handgun, where a booster isn't needed. You still mount the can with a piston for your thread.
Will it fit?
| Works with | SilencerCo cans with Osprey/Octane-style piston housings: Osprey, Octane, Omega 9K and Hybrid 46 |
|---|---|
| You also need | A SilencerCo piston for your barrel thread, e.g. 1/2x28 (AC25) |
| Does NOT work with | Tilting-barrel pistols (they need the booster spring in place), cans that don't use the SilencerCo piston housing |
