Dead Air Rimfire Accessory Thread Spacer | 1/2-28

The Dead Air Rimfire Accessory Thread Spacer 1/2-28 is a direct-thread spacer engineered to correct longer-than-standard barrel threads so rimfire suppressors retain proper blast chamber spacing. It is intended to reduce wear to suppressor internals by restoring the designed gap between muzzle and baffle stack. The spacer uses internal threads to remain affixed to the barrel when a suppressor is removed, providing consistent alignment for repeatable use.
