I've been thinking bout this for a long time... we often have gun shoots here at work and we often play with the m4, beretta, shotgun *not auto*, mp5's. When I get a chance, I will record their sound and create a soundpack. For the other guns like the AK, Galil, Famas etc etc, i think it's going to be hard hehe. I have to wait till the "operators" play with them. They don't let us fire those suckers for some reason. One thing for sure, I will never fire a .50 cal sniper rifle again! My shoulders hurt after that one lol
