Barrel length: 318 mm in basic configuration;

12.5" for a 223.....what a joke...

90-95% of all shooting, in all wars since the mid-1800's, has been a t very, very close-range.

The "myth" of a sharpshooter aiming and firing at individual targets that he can specifically see and aim at (except, of course, specialized sharpshooters and snipers!) just doesn't happen in real combat.

A short barrel and a small caliber bullet is adequate, just as Stoner originally designed in the AR-15 before the Army firearms officials screwed it by re-designing it as the first versions of the M-16.
