Nerf Crossfire, did all the modding on this one myself. <3 It has a ring on the bottom for a charm, we currently have a charm on it that we mean to replace. I let an unattended kid play with it at a convention and he dropped it, breaking off the key portion of the charm. It was originally a key that would unscrew from the base so you could put big beads on it. We'll probably find an identical key and put that on there so the owner can customize it with their own beads later.

almost looks like a Warhammer 40k bolt pistol XD
very nice mod work on that though, looks like it'd be perfect for a cosplay prop of some sort :3
