For use with a standard 25 round .22LR magazine to convert it to a Bolt Hold Open capable magazine.

Does not work with 10 round .22 magazine.

This kit is for use with the BHOA Actuator. The BHOA Actuator was designed to work with CMMG .22LR Magazines. Extensive modification is needed for the BHOA Actuator to function with Black Dog Mags.
