People With Machine Guns Drawing

Ensure annual headspace gaging and inspection has been done and that the next gaging and inspection are scheduled. As a minimum requirement, for Active Duty M249 machine guns headspace, gaging and inspection for both weapon and spare barrel assembly should be verified annual by Direct Support Maintenance. This requirement could be increased to four times a year, or after each training cycle, depending on usage factors. For Army Reserve and National Guard weapons, the period is 2 years unless inspection shows need for gaging more often due to usage.

Headspace gaging and inspection not performed.
