I seek .22lr conversion mags for ONLY the Colt or DPMS .22 AR setup. The Colt/DPMS mags are the ones that look like a somewhat shortened black 20-rnd AR mag. The DPMS dedicated .22 uppers use a variant of the Colt mag; I can grind off a projection on the Colt mag to make it work with the DPMS .22 upper.
Note - the setup CANNOT use: 1) the M261 inserts that fit inside an AR mag, 2) the white nylon mags that work with the Air Force setup, or 3) the slim-looking Ceiner 10 or 30 round mags.
I am a customer for either one mag or for several. Contact me at email@example.com
