I have been kicking around the idea of making a purchase for quite some time. Now that the prices are coming back down it's time to put a little more thought in this. Who makes the best AR's? I wold assume that Bushmaster and Colt would probably be top of the line but what about all the other brands like Stag, Olympic, Rock River? Is the quality the same? What brand did you buy and why? Is there any certain ones to steer clear of and why? Thanks for the info in advance.
