The SilencerCo AC114 Delta Thread Spacer 22 LR Steel Black Oxide 1/2"-28 tpi is designed to ensure proper rimfire suppressor seating on firearms with 1/2—28 threaded barrels when the threads extend beyond the recommended .400 inch, taking up approximately .25 inch of thread so the suppressor seats reliably.
