Just some number: An Ak-47 shots at 600 RPM, so 10 shots per second...them you can empty the magazine in 3 seconds!
The French FAMAS shots at 900 RPM ! so 15 shots per second...empy the magazine in 2 seconds !

I have researched many technical informations on modern the weapons...i have implemented all this in my demo. Not good graphics, but itīs a very realistic simulator.
