Tokyo Marui M870 Tactical Shotgun
Thank goodness for Tokyo Marui, which continues to innovate for the Airsoft market. Their latest invention is a novel new shell based system that allows their M870 shotgun to shoot between 3 to 6 BB's at a time (it's either 3 or 6, you can't choose anything in between). Going with tradition of it's older shotgun lines, this new M870 also has 3 inner barrels, each equipped with a fixed hop-up. Each shell has a capacity of 30 BBs, so you can keep shooting until the shell runs out of ammo before ejecting it. The gun only holds one shell at a time, and it only comes with 1 shell on purchase. Of course, additional shells are available for sale separately. The gas is stored in a removable gas cartridge stored in the stock of the gun, and additional gas tanks are also sold separately.
