I'd take an AR-10 if someone gave it to me, but probably not buying one unless I hit the lottery really hard. Had a bad experience in Basic Training with an M-16, hope they've gotten the bugs ironed out of them by now. That was about 50 years ago. I've seen photos of an AR-15 with wooden furniture. but I'd want a steel action, even so. I find the weight a bit helpful.I have a few of both but prefer the wood and steel also only have the other because cant find them in wood and steel.
