A fun contest would be to set up a dozen soda bottles spaced a foot or two apart at 30 yards and try to take them all out with a single continuous burst.
who engineered & built this most kick-ass version of a 9 mil? that would be a good fair/carnival game! That said I'm not a fan of full auto. It does have it's place under certain conditions but in any shoulder fired non-belt fed weapon (or even handgun) it's pretty much worthless or a detriment rather than an asset. Switching from full auto to three round burst in the M16 was a very good move IMHO. Even in a low recoil weapon like the M16 it's still hard to keep a tight group after three or four rounds on full auto.
