SilencerCo Delta Rimfire 1/2×28″ Rifle Thread Spacer- Black Steel

Used on 1/2×28 threaded barrels where the threads are longer than the recommended .400″, this spacer takes up approximately .25″ of threads so the rimfire suppressor seats properly.

Many gun companies and gunsmiths make a common mistake and thread .22 LR barrels at AR-15 thread lengths. Most .22 silencers on the market will not shoulder correctly on AR-15 thread length. This spacer shortens AR-15 thread length to .22 LR thread length while ensuring concentricity.
