Corrective
Action
• Pull back on charging
handle so that the slide is
back to the sear tooth and
continue firing.
• If the stoppage reoccurs,
disassemble the wpn;
check how the ammunition
is packed in the box and
whether the link belt is
properly loaded.
• If the belt is properly
loaded, turn the gas
regulator to a higher
position.
• At the earliest possibility
clean and lubricate the
machinegun.
• Interrupt fire by pressing
the belt towards the feed
mechanism with your
hand.
• Clear the wpn; inspect
the sear and the notched
lug on the frame of the
slide. If they are free of
defects, switch gas
regulator to a higher
position and lubricate the
interlocking parts.
