Earlier this year we posted about an ammo vending machine in a private gun club. Well Mike Robinson of Tactical Graphics purchased a crane/claw game for his gun store. Instead of toys and plush animals, he lined the bottom with empty brass and filled it with Magpul accessories.
Seems like a fun way to get a couple of coins out of your customers. If I were him I would have special deals. If you spend so much money you get a free play with the claw machine. Or give free plays to frequent customers.
