For folks who just want a cheapo AR for home defense and little shooting, ATI is selling their plastic (infused polymer upper and lower) for $369 now. Weighs about a pounds less than mil-spec aluminum. think ClassicArms.com has them. I have never been a fan of plastic guns, although I have several Glocks and others in my safe and all work great. I build my guns as close to mil spec as possible but I run them hard as well and I do shoot surpressed most of the time.Interestingly enough, when my daughter got off work, she and her hubby stopped by the house. She was saying she'd like an AR, but couldn't afford one. I spout off with, "Why don't you build one?" She says it would be too hard. I said, "Really? Once all the parts are in hand, a few hours should be all it takes. I already have all the tools needed from my last build." Guess what we're doing as a family this winter? Building AR's. Heck, I might build another myself, just to stay in practice.
