I'm a noob. I've had lots of guns over the years but never an AR. I'm seriously (by seriously I mean I'm just waiting on a check)considering my first. I've been looking at stag and cmmg.. Also s& w. I just want to hear opinions from you seasoned professionals. give me some package ideas....you know...gun, scope, accessories... I'm on a budget. My range for just the gun is about $7-800. Thanks in advance.
