Here is a pic and link to the new DMPS drop in .22 unit for the AR-15. It's evidently an all steel copy (polymer mags) of the old Colt R-6222 drop in unit and the mags are interchangeable with the old Colt units. The mags are the same mags also used with the DPMS/Panther Arms .22LR AR-15 dedicated uppers.
After doing some checking, the polymer 10 round mags for this unit are quite plentiful and even outfits like Midway carry them. I'll bet that getting a quality, reliable DPMS unit will be a lot less of a crap shoot than with a Ciener.
My next .22LR unit will be one of these. It's DPMS product code is BCBA-22M.
