Yes we can do that......Cabelas has some nice used guns that are decently priced. Like Don said there can be great guns at a pawn shop and some not so nice ones...
Great suggestion, I just bought a Ruger Stainless Ranch Carbine outta the "used" gun rack. It was actually 100% (brand new condition) and after about 1 minute of haggling :-) was able to get it down $100.
