BB2K Airsoft deviates a bit and reviews a CO2 powered airgun that we strongly recommend for target shooting or plinking and not for airsoft skirmishes... "Today I show you the Colt S.A.A. (Single Action Army) from Umarex. This revolver is an airgun, which is operated with 4.5 mm steel BBs and CO2. The power is more than 5 Joules and the 4.5mm steel BBs speak 100% against use in Airsoftgames! Hazardous plug shots and injuries can be the consequence!"
