6.4. Feedway Stoppage (Jam)
A feedway stoppage occurs when one or more rounds are trapped in the upper receiver and stop the cycle of operation.
To clear this problem:
1. Place the rifle on SAFE.
2. Remove the magazine (You might have to pull downward with some force to remove the magazine from the magazine
well due to the jammed cartridges).
3. Cycle the bolt carrier assembly several times to clear any rounds from the receiver; and
4. Lock the bolt carrier to the rear, conduct a visual and physical inspection of the chamber to make sure the chamber
has no obstructions; and
5. Insert a fresh magazine and continue to fire the rifle.
CAUTION: Always remove the source of ammunition (magazine) prior to attempting to clear a stoppage that requires
retracting the charging handle/bolt carrier assembly as unintentional release of the spring loaded bolt carrier assembly
could detonate live cartridges lodged in the upper receiver.
