Russell, I agree with you. Most of my ARs are nearly stock. And I don't think one must spend a *ton* of money, necessarily, to get a decent setup.
Still, shooting guns, especially semi-automatic rifles with relatively high-capacity detachable magazines, tends to be a hobby of significant expense for most people, including myself, and I make a pretty decent living.
My other problem is that, when I'm tired, I occasionally lose patience, and blurt things out that I might not otherwise say/write. Had I been in a better frame of mind, I might have asked what his intended role for the rifle was. If the answer to that was "have fun at the range" (and not "my primary means of defense"), I'd have said "fine, go have fun."
I think most folks know me well enough by now to know what I would have said if the answer was "my primary means of defense."
