Tokyo Marui never ceases to amaze with their innovative new designs and improvements in the airsoft world. Once again, they manage to bring us a product which will set the standard to what future guns will be measured with. The all new M870 full metal gas operated pump action shotgun combines realism with convenience for those looking to utilize a shotgun for CQB skirmishing. This innovative new shotgun has multi shot capability allowing for multiple BBs to be discharged with one pull of the trigger; with a quick flip of a switch, the M870 can switch between 3 and 6 BBs discharged with each shot. Until now, shooting more than 3 BBs at a time was reserved only for shell ejecting shotguns; the M870 however uses the same shells as the original TM shotguns as well as the UTG spring shotguns making it easier to keep track of your shells and with the added advantage of having more ammo per shell. The gas operated system allows for a smooth racking action compared to spring powered shotguns to allow for rapid follow up shots and unrivaled speed. Last but not least, lets not forget distinct and satisfying sound of a pump action shotgun being racked.
