This is a full metal, pump action airsoft shotgun. This gun shoots at 350+ FPS with 0.20g BBs and is spring powered. It is a single shot shotgun, one BB for each time you pump the handle. The gun itself weights 4.5 pounds and feels very realistic when held. A sling mount can be found at the front of the gun as well as the back of the rear handle. The only non-metal parts on the gun are the wood colored handles which are made of study ABS plastic.
