Firstly, rimfire won't require a BB or AW registration so featureless shouldn't even be a consideration. This is my primary reason for building a complete dedicated AR15-22LR.

Just build your AR22 like you would any other AR15, except you need a 22LR bolt (obviously) and I would highly recommend a 22LR barrel. CMMG happens to make both the bolt and the barrel. Everything else you can use standard AR parts (upper, lower, hand guard, trigger, etc).

As for magazines, there are Black Dog Machine magazines, CMMG magazines, and S&W M&P15-22 magazines. There might be others out there but these are the big 3 IMO. And of the 3, the S&W mags are the best IMO, but they require an adapter to use (Boonie Pack Better Mag adapter). This adapter also has a bolt hold open feature that holds the bolt open after the magazine is emptied, whereas the other magazines will not do this. Hope this helps.
