Product Description
SilencerCo’s 1/2x28 Rifle Thread Spacer ensures your rimfire suppressor seats correctly on over-length threaded muzzles. Machined from steel with a durable black oxide finish, this spacer shortens the effective thread area while maintaining concentricity, protecting your baffles and keeping your suppressor aligned. Designed for .22 LR rifles with threads longer than the typical rimfire specification, it takes up approximately 0.25 inches of thread and delivers a clean, seamless fit at the muzzle.
