Get a Ruger 10/22 .22lr, fully customizable to look just like an AR, the AR stocks for it are on MidwayUsa.com or Brownells.com, any of these are awesome (Archangel 556, Troy T22, G36 Nomad, and the best one is a Nordic AR22 kit, you buy an Ar15 free float handguard, and an AR pistol grip and collapsible buttstock, while only needing a buffer tube, no buffer, no spring. Anything that fits on an Ar15 will fit on this kit. Easy to install. The HC3R is a 30 round rapid rifle reload magazine, it has a secondary ammo pocket that holds twenty more rounds with stripper clips for $40 dollars on Rimfiresports.com. Impact resistant resin molded, extremely reliable I have a few, steel feeding lips and breakdown and easy to use. The second mag that is available is the T125, by Tactical Innovations, for about 70$ on RimfireSports.com as well. Both magazines I mentioned are great, feed reliably with zero wiggle.
