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.
Yeah, that AR is sweet. I kinda like the shotgun too -- reminds me of lime jello -- but it is a little bit of a "conversation piece." I was gonna say it is "impractical" but so is a base model 870 tactical when you think about it.
