RIMFIRE SPACER 1/2x28 - FOR LONGER THREADED BARRELS
.22LR barrels should be threaded 1/2 x 28 TPI with .400 length of thread (LOT). When you want to use your suppressor or similar muzzle accessories on barrels that are 1/2 x 28 but have longer threads (such as an AR15), our RIMFIRE SPACER ensures concentricity from the suppressor to the barrel while covering .230 of the thread between the barrel shoulder and the muzzle accessory.
Avoid potential damage to your muzzle accessory by screwing it on too far. Our Rimfire Spacer is the perfect solution.
