SilencerCo Delta Thread Spacer 1/2×28 — .22 LR

Description

The SilencerCo Delta thread spacer is designed for 1/2×28 threaded barrels that are longer than the recommended .400″ thread length for rimfire devices. This spacer occupies approximately 0.25 inches of excess thread so a .22 LR suppressor can shoulder and seat correctly. It is a compact mounting accessory machined for durability and repeatable alignment.

Commonly used where AR-length threading has been applied to .22 LR barrels, the spacer restores appropriate rimfire thread length while maintaining concentricity. Compatible products listed by the manufacturer include the Sparrow 22, Switchback 22, Warlock 22, and Spectre 22.
