This is *the* place to go for ARs, AKs, and parts. Free internet transfers is the icing on the cake. Their Magpul gear is cheaper than most online stores. Only downside is it seems a lot of folks just go in to shoot the breeze, so you sometimes have to wait to be helped while another customer keeps them busy chatting. But I have never had a bad experience here. I recently moved almost two hours away and still do my FFL transfers here (I stop by on the way to my office). Hard to beat this shop!
I don't understand the negative reviews here. You want real, honest reviews, go on any of the firearms forums. This place has a reputation for being absolutely top notch. If you don't believe that, go in there and see how many people flock to this place. It's an hour from me, but worth the drive.
