SilencerCo Fixed Barrel Spacer, Stainless Steel - AC22

This is a fixed barrel spacer designed for use with SilencerCo Osprey and Octane suppressors on firearms with fixed barrels, such as rifles and submachine guns. Made from 17-4 stainless steel and heat-treated for durability, it replaces the piston booster spring to allow piston operation on fixed barrel platforms. The spacer disables movement in the suppressor's internal components for reliable performance.
