I just inherited a Colt-marked 22 conversion kit for the AR15. But…it came w/o mags. I need to know if a Blackdog Machine mag will work with it.
TIA,
Vic
the Ciener kit BDM mags will not work with it. Im not sure about the olympic arms BDM mags though. Hopefully someone where can help you.
Spoke to BDM today and they said none of their current prods work w/a Colt kit. 
However they did say they’re working on one that WILL work and hope to market it soon.
