Re: CHEAPEST ar15 you've seen
If your handy, you could find parts for sale in the classifieds on here AR15.com etc, and build one pretty cheap. I'm in the process right now, if you assemble the upper yourself you'll save the most $$$. I think mine will be $450-$500 when I'm done. The problem is staying "cheap" too many good deals on upgrades keep catching my eye.
I like things that go "bang"... I love things that go "BOOM!"
