first off, if they can alter the physics of the 40mm and m67 grenades, why not just do the same for rg's?
secondly. are you talking casualties as in any injury, or casualties as in mortal wounds? cause even with the added range, the injury would just mean a (bigger) tick off the health bar.
(and to my uneducated ears, 75m sounds pretty far for such a small device)
the question I have is weather its worth all the trouble to do this. it would be cool to have them, but its still boils down to added work on someones plate.
m-16 is more than adiquate to represent all grenade firing rifles in the mean time.
far as acog+203 goes, I dont use acog on mine. and I dont use the iron sites either.
strange or not, I find I prefer to shoot with it in the side position during inf. (and I have found myself able to put nades through windows and other tight spots on occasion)
I can only assume that thats how I would fire the real thing if it was given to me with no prior instruction. the guns barrel blocks my view if I use the sites.
