Airsoft Atlanta test the Airsoft Innovations 40 Mike Gas Shell at different distances... "1st part: 40 Mike demo - one shell going off, 150 (approx) BBs, from exactly 30 feet away.   2nd part of the video is four (4) 40 Mikes going off at once from around 45-50 feet away.  A much safer distance to shoot from. At the end of the video, we slowed it down to show you the sequence with our high speed camera."
