Dead Air Thread Spacer | 1/2×28

The Dead Air Thread Spacer 1/2×28 is a direct-thread spacer engineered for rimfire barrels with longer-than-standard threads. It restores the intended blast chamber spacing for rimfire suppressors, which helps reduce baffle erosion and maintain long-term performance. The part includes internal threads so it remains affixed to the barrel when the suppressor is not installed. Intended use includes range training and precision rimfire target work.
