The F11C-2 guns are located ahead of the cockpit, one on each side of the fuselagee. Two .30 calibre guns are carried as normal load but the right hand gun may be alternated with a .50 calibre gun. Access is gained to the entire installation by lifting the hinged doors of cowling on the sides of the fuselage. The distinct advantage of this installation arrangement is that the armorer may stand on the deck just ahead of the lower wing or sit on the leading edge of the lower wing to install, bore sight or service the guns, all the time working at a height only slightly above his waist. In any of these operations he has no obstruction or intereference to contend with. The ammunition boxes are of the sliding type insterted from the side, and are locked in place by merely rotating a handle used in handling the box. It is readily seen that servicing may be rapidly accomplished.

The guns are located outside the cockpit lining; consequently, the pilot will experience no annoyance from the noise or fumes produced in firing. Rounds counters are furnished in the cockpit to show the exact number of rounds remaining in the ammunition boxes at any time.
