Overview
This adapter is designed for shooters who want to run Smith & Wesson M&P15-22 magazines in an AR-15 equipped with a dedicated .22 LR upper or a CMMG conversion unit. Its independent bolt catch is intended to hold the bolt open on the last shot and remain locked back after the magazine is removed, which can make empty-chamber checks and reloads more straightforward. The unit is made with a 6061 aluminum body and a case-hardened 1018 steel bolt catch, and it is not compatible with DPMS, Chiappa, or Tactical Solutions units.

Considerations & Trade-offs
- Requires Smith & Wesson M&P15-22 magazines, so it adds a magazine-specific dependency rather than using standard AR-15 .22 LR magazines.
- Not compatible with DPMS, Chiappa, or Tactical Solutions units, which limits use with some dedicated .22 setups.
- Designed for AR-15 rifles fitted with a dedicated .22 LR upper or a CMMG conversion unit, so it is not a universal adapter for all AR-15 configurations.
- The natural-finish 6061 aluminum body and case-hardened 1018 steel bolt catch are functional, but the product description does not indicate any protective coating or finish beyond the natural aluminum surface.
