I'm gonna stop you right there, you just said an AR-15 is a high-powered rifle. It is obvious you don't know anything about guns and I shall ignore anything you say from this point on.
I work in the gun dept at academy sports and outdoors and the mmr is a very nice gun for 650. I haven't heard any negative things from customers. We sell them pretty quickly too. I'll probably end up picking one up if I can ever get my hands on one.
