They dont tend to have a huge selection of stuff its kind of a movable feast on stock but Glen is a good guy and if you have a particular want go talk to him and he will get you what you want at a good price.
Having said that he does have around 6 to 8 AKs and the same in ARs on the rack, not being into shotguns myself really not paid much attention but he maybe has a doven on the shelf.
