11. Head space Adjustment a. Introduction. Headspace is the distance between the face of the bolt and the base of cartridge case, fully seated in the chamber. Head-space adjustment is correct when the following conditions are met:

(1) The recoiling groups are fully forward.

(2) There is no independent rearward movement between the bolt, barrel, and barrel extension.

b. Importance of Correct Headspace. Improper headspace adjustment can cause improper functioning of the gun and, frequently, damage to parts and/or injury to personnel.

c. When to Check Headspace. Headspace is checked and set prior to firing. Other instances include:

(1) When the gun is assembled.

(2) When the barrel or any major group or assembly within the receiver is replaced.

(8) When there is doubt that correct head-space is set.

d. Gages. The headspace and timing gage consists of a headspace gage and two timing gages (fig 80). These gages provide an accurate means of checking the adjustment of headspace and timing.

Note. The headspace and timing gage should be kept with the gun at all times.
