Id love it to have realistic rate of fire for each gun, power too, but that would make it too complicated (for example, having an AK shooting 8mm at 70m/s and an M16 shooting 6mm at 100m/s
). Either way, I find that many upgraded AEGs have an unreasonably high rate of fire, combined with a hicap, makes up for very unrealistic firing, just becoming an ammo hose!
I think that a firerate between 500-900rpms would fit most automatics, if you could make per gun make, it would be great in realism. For example, AK going off at around 600rpm, and the M16 at around 800-900rpm. You can use the same system, but put a heavier bolt on the AK to both slowdown the firerate and have it have more recoil just like real steel.
My dream gun would be a full auto all steel and wood AKM with full stroke, heavy bolt gas blowback, 600rpm, 8mm 715fps (instead of 7.62mm at 715m/s on real steel), with standard 30 round magazines and enough gas in the magazines resevoir to be able to fire off all the shots the same FPS and firerate in as cold as 0 C temperature. A nice 75 round drum mag with a larger resevoir (sure has the room for it) to support all the rounds under the same condtions would be a nice accessory for later. Ah... a man can dream
Cheers!
