DISASSEMBLY

1. Once the firing pin is separated from the bolt body, use a 1/16-in. punch and 4-oz hammer to drive out the ejector retain-

ing pin (5) from bolt body assembly (1).

2. Remove the ejector (4) and the ejector spring (3) from bolt body assembly (1).

3. Use a jeweler’s screwdriver (.080), pry and lift the extractor (2) out of the recess rim in the bolt body assembly (1).

INSPECTION

1. Check that the bolt handle (6) is firmly attached to the bolt body assembly (1) and the solder has no cracks.

2. Inspect the face of the bolt for cracks, chips, or pitting. If unserviceable, request WIR disposition from Material Man-

ager, Albany, GA.

3. Check the ejector (4) for cracks, chips, or burrs and for proper tension by depressing inward; some resistance should be

felt against the ejector spring (3) and the ejector should return to its original position. If unserviceable, replace ejector

and/or ejector spring.

4. Check the extractor (2) for cracks, chips, or burrs. Check function by depressing inward; some resistance should be felt

and the extractor should return to its original position. If unserviceable, replace extractor.

REASSEMBLY

2. Install the ejector spring (3) and the ejector (4) on bolt body assembly (1).

3. Using a punch and hammer, install the ejector retaining pin (5) into the bolt assembly (1).

CAUTION

or long firing pin protrusion problem.

nance (WP 0013 00).
