Selector Lever Operation with Stock folded
rounds fired in a very minimum period of
time. A cook-off can result when the prim-
er is exposed to extremely high tempera-
ture, but still will require approximately
30 seconds for the heatto ignite the primer.
In the event a cook-off occurs, immediately
remove the magazine and eject the cham-
bered cartridge. Under all above conditions,
be particularly careful as to the direction
the rifle is pointed.
2-30. DOUBLE FEED. Double feed may
occur when initially loading the rifle,
caused by failure to allow the first round to
fully chamber and pulling the charging
handle to the rear with the first cartridge
still held by the extractor. The bolt carrier,
going forward, will attempt to strip the
second round from the magazine, resulting
in a jammed condition. Remove the maga-
zine and pull the charging handle to the
rear, releasing the first cartridge.
