The Kiwis are having all the fun with BLTech's Gun Sound Simulators which they call B.O.S.S. In this video of an airsoft base assault. There are more BOSS units in play including one mounted on an M249. Just listen to the sound of battle and take note that only 5 of units were being used. Just imagine a big milsim event where everyone is equipped with one. Event organisers must plan to use these where the local population would not complain.

In what probably many airsoft players would swoon around the world is finally here and word is going out fast about this latest innovation in airsoft. If you're looking for something really realistic apart from recoil, blowback, and shell ejection, the gun shot sound coming from airsoft gun would probably be the ultimate and the Kiwis finally found the first solution to it.
