Tokyo Marui are continuing with their M870 shotgun trend that shoots 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.
The M870 Breacher is a shorter version of their early M870 with a different grip and pump action grip. Since there is no stock, the gas tank is a different shape and is stored in the grip itself.
The good news is that this M870 can take green gas! One full charge can power up to 50 shots of 3 BB’s at a time.
