Yeah I've been there a few times and have bought some guns from them.
They have a lot of curio and relic stuff. Their website sucks a lot, but they are nice enough in person. Bought an AK and a stripped AR15 receiver from them. Prices aren't as good as CDNN, but not too bad for the DFW area. Lots of firearm odds and ends, mags, stuff. Lots of old military guns, a few new ones. Lots of cheap guns. It's a long way to drive for me from Plano, but always fun to visit since you can handle all the guns, they are not behind the counter (great marketing tool - playing with guns makes you want to buy them). Just be advised their in store price is a about 5% higher than web price, they will tell you this if you call.
It one of those places that's hard to leave without buying
something(at least for me
)
