COCKING HANDLE

release the latch and spring.
c. Inspection. Check the cocking handle components for burrs, cracks or distortion.
d. Repair. Replace defective latches or springs as required. Replace handles which are
distorted sufficiently to bind in the receiver or against the carrier key.
e. Reassembly and Replacement. Reassemble and replace the cocking handle in reverse
order, ensuring that the latch axis pin does not protrude from the handle upon assembly.
UPPER RECEIVER
26. Inspection. Inspect the upper receiver for dents, cracks, gouges, corrosion or distortion.
Small dents which do not effect the operation of the weapon shall not be cause for rejection.
However, upper receivers containing cracks or holes shall be condemned. When inspecting the
C7A1 upper receiver ensure that the optical sight grooves are correctly formed.
27. Repair. Backload weapons with non-serviceable upper receivers. Repair minor damage
to the upper receiver by the following procedures:
