I have an Armalite AR-10A4...I've been exceptionally satisfied with it. Mags are a little on the expensive side, but the factory frequently runs package deals and accessory sales, The factory mags are well made and durable, so once you've got yourself set up with what you think you'll need, the need to replace any is going to be very, very rare.

I will second what Joe said, AR-10 is a great rifle. Although, there have been many suggestions and I suddenly feel the urge to hit the store again soon heh. I mean, I do need more, I lost all my other firearms in a tragic hangliding accident over an active volcano.
