I was at Buds location in Paris on Saturday. They do have several AR's in stock, and ammo.
The web site does not list all the guns at the store, although some of the guns on the web site won't be in the store. But the store generally has most of the popular items in stock.
I've bought five or six guns from there web site without a problem. The web price does include shipping but if you use a credit card they add I think 3%.
One time I did order a M1A, but choose the wrong model by mistake. I sent a email letting them know which one I wanted and it was handled without a hitch.
On high end guns you can save quite a bit over a local shop, but guns under 500 you might only save 20 or 30 bucks, so I try to buy those local.
On the M1A I bought it was around 1700, the local store was over 2000. But a Glock 17 was only 20 bucks less, not worth the tranfer fee.
Another reason I like using there web site is because the guns come from a warehouse not in the store. That means the guns haven't been handled by who knows how many people, no dry fire's, no finger prints.
Overall its my favorite gun store.
