Running a .22 LR rifle with 1/2×28 threads that are too long for your rimfire can to seat on the shoulder? The SilencerCo Delta Rifle Thread Spacer solves it. Drop this steel, black-oxide spacer behind your suppressor to “eat up” excess threads so the can bottoms out correctly and stays concentric. It’s purpose built for 1/2×28 rifles and takes up about a quarter-inch of thread, which brings over-length AR-style muzzles back to rimfire spec. Affordable, simple, and the right way to protect your baffles.
