Silencer Co | Delta Thread Spacer | 1/2×28

The Silencer Co Delta thread spacer (AC114) adapts 1/2×28 rifle-length threads to the shorter shoulder required by many .22 LR suppressors. It is intended for use where barrel threads exceed the recommended .400″ and takes up approximately .25″ of threads so a rimfire suppressor seats properly. Constructed of steel with a black finish, the spacer helps maintain concentricity between the barrel and the suppressor. It is designed specifically for use on 1/2×28 threaded barrels.
