BeeStingerAirsoft goes into action with the Marushin M1 Carbine CO2 at OPS Field. This is the CDX version that comes with a real wood stock that has an initial muzzle velocity of around 350fps for the export version, though this one meets Japanese regulations... "Gas guns only game day at OPS was perfect for the Co2 powered M1 Carbine. 1911 pistol proved to be an effective secondary."
