Not one to purchase guns, but one that has other firearm related stuff: reloading equipment, fail accessories, sights, scopes, armorer's tools, etc. The pocket and fixed knives from Blades can go in there (the kitchen knives can go to the Cooking community, thus dissolving Blades) and the more molle-type backpacks from Outdoors can go in there as well.
...just an idea. I dunno. First post. Don't hate me if this has already been addressed.
