SilencerCo Delta thread spacer for 1/2x28 barrels. Steel construction with black oxide finish. Corrects AR-15 length threads for proper .22 rimfire suppressor seating.
This precision-engineered thread spacer solves a common problem in rimfire suppressor installation. Many manufacturers thread .22 LR barrels at standard AR-15 thread lengths, which prevents rimfire suppressors from seating correctly.
When .22 LR barrels are threaded to AR-15 specifications, the threads extend beyond the optimal length for rimfire suppressors. This prevents proper shoulder contact and can compromise suppressor performance and reliability.
The Delta spacer reduces thread length by approximately 0.25 inches, effectively converting AR-15 thread length to the correct .22 LR specification. This ensures your suppressor seats flush and functions as designed.
Proper suppressor seating is essential for consistent performance, accuracy, and longevity. This spacer is a simple, effective solution that takes the guesswork out of rimfire suppressor installation.
