INSPECTION
1. On the stock, check the bedding on top and under trigger guard for cracks, powdering and shrinkage. Pay special atten-
tion to the bridge on stock. Check for cracks. Check that all edges are rounded. Using a rag dampened with acetone,
clean glass bedding surfaces of the stock of all oil, grease, dirt, and debris. Remove all excess oil from the barreled
action where it contacts the glass bedding.
2. (M40A3) Inspect the muzzle end of the barrel (5) for a serviceable crown (6). The lands and grooves should come to a
sharp end with no nicks or burrs. If unserviceable, evacuate to a higher level of maintenance. (M40A5) Inspect muzzle
break (8) for looseness, damage, and/or cracks. Inspect bearing surfaces (7) for burrs. If unserviceable evacuate to a
higher level of maintenance.
3. Inspect the external surface of the barrel (5) and receiver (9) for burrs and visible cracks. If found, evacuate to a higher
level of maintenance.
4. Inspect inside the receiver (9) and chamber area for nicks or burrs that would cause hard extraction or chambering a rup-
tured case, or break extraction upon firing. If any of these conditions exist, the weapon is unserviceable. Evacuate to a
higher level of maintenance.
