Here's Bob testing ACM 6mm M500 Shotgun Airsoft Gun which is right now in stock at Airsoft GI... "The ACM 6mm M500 Shotgun is a multi-shot gas propelled pump action airsoft shot gun. Each action loads three 6mm BBs into the barrel and when fired all three are propelled out by a gas propellant, preferably green gas. The furniture and pump are made of a durable ABS plastic. The body, barrel, and tubular magazine are constructed of metal. The build quality and attention to detail give the ACM M500 a realistic look and feel. If you're looking for a powerful and realistic shotgun on a budget, the ACM M500 would be something to consider.
