The video is a test of the newly released Tokyo Marui M870 Tactical Gas-Powered Shotgun and comes with a full review by the Gungineer... "This is an impression of M870 TACTICAL gas shotgun that is sold by Tokyo Marui. Such as double-hop up to apply a 3-hop generation / 6 generation switching systems, even multiple development new technology offers a variety of power-packed action."

The guys from the Japanese Gungineer Airsoft Forum and Gunsmith Engineer gave the DCS A-TACS FG BDU made by Propper International a video test. What they find about this is that it's close to multicam, and being lighter shade of green, it's bright in forest or bush, but quite effective in grass.
