Ar-15/M16 Better-Mag S&W M&P 15-22 Magazine Conversion Adapter - Better-Mag S&W .22 Mag Adapter

Easy-to-install adapter converts the reliable, easy-to-load Smith & Wesson M&P15-22 magazine for use in an AR-15 fitted with a dedicated .22 LR upper or a CMMG conversion unit. Unique design has an independent bolt catch that locks the bolt back on the last shot and keeps it there when the magazine is removed, just like on a standard centerfire AR-15. This allows easier reloads and provides a visual indicator that the gun is empty after the last round is fired. Will not fit DPMS, Chiappa, and Tactical Solutions units. Mfg: Boonie Packer Products SPECS: 6061 aluminum body, natural finish. 1018 steel bolt catch, case-hardened.
