Bring them on! The more, the merrier! That's the nice thing about free markets, more options. In this case more M870 airsoft shotguns that are very realistic in operation are coming out. We have posted news about the Airsoft M870 Shotgun by Uralskaya Kuznica and now Red Army Airsoft Club put out  a teaser video of their upcoming review. Alexander informed us that this review will also include a comparison with a real Remington M870.
