We really need to get one of these B.L.Tech Gun Sound System units as it's the most realistic right now. With full auto airsoft now allowed in New Zealand, what we see, or rather hear in the video, is the B.L.Tech Gun Sound System being fired in full auto and heard by airsoft players. The actual airsoft gun is not shown as it is being fired from afar and it's a very distinct sound. This may have implications in using this sytem at game sites and players may just be able to use it in locations that are from populated areas as people might either complain of the noise or panic due to its realistic gun sound.
