Airsoft GI got the Airsoft Innovations 40 Mike Gas Shell in stock and for this review, they use GI Justin as the guinea pig to test its power... "The 40 Mike Gas Shell BB Shower is a brand new concept Airsoft Innovations has presented to change the expectations of an airsoft grenade shell. A stream of 150 BBs shoots out of the shell with a 10 foot spread and up to 100 feet in range. This shell shoots at about 240 FPS per shot with its patented Quantum Drive Technology. Use the Airsoft Innovations 40 Mike to accurately take out a couple of opponents with a barrage of BBs head straight toward your target."
