The C02 version of the Fabarm STF12 airsoft shotgun is available now at Evike.com. Matt shows you the shotgun, which uses the Marui gas shotgun system, in this video... "One of the most efficient shotguns in its class, the FABARM STF12 CO2 powered shotgun features the Tokyo Marui multiple shot system combined with the convenience of easy to change 12 gram CO2 cartridges. The STF12 is able to fire 3 or 6 shot bursts per cycle of the action without having to deal with picking up ejected shells. The replaceable CO2 cartridge system solves the issue of having to fill gas directly into a reservoir; for players that favor HPA setups, an option for an HPA adapter is available. Being gas powered instead of a spring driven piston, the action cycle is smooth and effortless, properly mimicking the feel of cycling a real shotgun."
