Silencer Co Delta Thread Spacer | 1/2×28 AC114 | .22 LR

The Silencer Co Delta thread spacer (AC114) is a steel spacer designed for 1/2×28 rimfire threaded barrels. It reduces excessive AR-15 thread length to the recommended .22 LR seating length so rimfire suppressors shoulder and seat concentrically. The part is finished in black (black-oxide noted in product references) and is intended for use where threads exceed the recommended seating length.

Typical applications include range use with suppressed .22 LR rifles and rimfire target or plinking setups that require proper suppressor engagement. It is a simple, mechanical accessory intended to correct thread length for reliable suppressor seating and alignment.

This spacer addresses a common threading mismatch on .22 LR barrels threaded to AR-15 lengths; by taking up approximately .25″ of excess thread the Delta spacer helps the suppressor seat properly and maintain concentricity. It is compact, made of steel, and finished to resist corrosion during normal range use.
