Due to its size relationship to the M2A1 .50 cal. ammo can, te PA-108 Ammunition is often called the 'Fat-Fifty.' On the other hand, when used to carry four 200-round magazines of linked 5.56mm ammo for the M-249 Squad Automatic Weapon (SAW), the PA-108 is called the 'SAW-Box.'

Another common use for the Fat-Fifty ammo box is to hold 1140 blank rounds of 5.56mm ammo in 20 round boxes. Other packaging for 5.56mm and for other cartridges have been used with the PA-108.
