Need some opinions/ advice from some of you "gun hands"

Thanks for all the good info, and thanks to whoever cleaned up the mess on aisle 556, or maybe, 223. I MAY just buy one of the suggestions listed, but frankly, the idea of a rifle with NO ties to federal goons is appealing, which got me going on the l "lower" thing initially. I resent the term "ghost gun." Hell I might just build one in .22LR !!
