Well the M&P 15 is better than a Colt and not as good as Noveske. At least they use 5R rifling.
Still waiting on some info here.
Who cares what standard of "quality" it is.
Why did you shoot your friends? That doesn't seem like a great way to keep a friend.
I've had a pair of them for about 2 months now and so far I'm really happy. Great for AR practice on a budget.
