INSPECTION
1. Check that the bolt handle is firmly attached to the bolt body assembly and the solder has no cracks. If cracked, evacuate
to higher level maintenance.
2. Inspect the face of the bolt for cracks, chips or pitting. If unserviceable, evacuate to higher level maintenance.
3. Inspect the firing pin to make sure it is straight and has a smooth, round tip. Ensure that firing pin is clean and lightly
oiled. If unserviceable, replace firing pin assembly.
4. Check the extractor for cracks, chips or burrs and for proper tension by pushing toward the outer edge of the bolt face;
there should be some resistance and the extractor should return to its original position. If unserviceable, evacuate to
higher level maintenance for extractor replacement.
5. Check the ejector for cracks, chips or burrs and for proper tension by depressing inward; there should be some resistance
and the ejector should return to its original position. Ejector should depress slightly below the face of the bolt.
