Silencerco Rifle Thread Spacer 1/2X28 Black Barrel Adapter AC114
any 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.
