Figure 22. Stowage of Weapon.
6. Use M12 Storage Rack after modifying as described below.
a. The M12 storage rack is the correct arms rack in which to store the M4/M4A1 carbine. The carbine
must be stored with buttstock extended. The back-up iron sight must be mounted in rearmost slot
of upper receiver. When storing the M4/M4A1 carbine in the M12 storage rack a mounting bracket
(WP 0045, item 23) may be used for each carbine being stored. This option is for the convenience of
the person who opens and closes the storage rack to store the carbines.
b. To install the mounting bracket on the M12 storage rack, for use with the carbine, install the
bracket with the hooks of the bracket facing toward the carbine, so that the lower receiver
extension will contact the bent end of the bracket. The bent end of the bracket will hold the carbine
upright when the arms rack is opened. The bracket can be turned around when not in use for the
carbine to allow storage of the M16 series rifle.
c. When storing the M4/M4A1 carbine in the M12 storage rack, an adapter bar (WP 0030, Figure 6)
MUST be used for security reasons.
NOTE
It is necessary to either remove the carrying handle, if present, or ensure that it is in
rearmost position in order to secure the locking bars of the M12 rack during storage
of the M16A4 rifle and M4/M4A1 carbine. DO NOT mix carrying handles from one
weapon to another; it may change the zero of the host weapon.
d. To prevent damage to the mounting surface on the upper receiver it is recommended that the rail
protector (WP 0045, item 29) should be used during storage of the carbines and M16A4 rifle when
the back-up iron sight or some other accessory is not installed on the upper receiver.
