CAUTION

Extreme care must be exercised during the following procedure to ensure that the

striking force is not directed to the attaching screws and that the tube portion is not

enlarged or flared beyond original requirement. Such enlargement would permit loss

of gas pressure when the key and gas tube come together during functioning. The

edge of workbench is recommended.

1. Repair small dents and/or distortions in carrier key (6) using bolt carrier key tool (11) as follows:

a. Place the key and bolt carrier assembly (5) in a vertical position, supported so that contact is made

with the rear surface of the carrier key (6).

b. Insert the small end of the key tool (11) into the tube portion of the carrier key (6).

c. Strike the large end of the key tool (11) lightly with a 4-ounce, soft-brass hammer.

d. Repeat striking (gently) until carrier key (6) is reformed to original configuration.

e. If carrier key (6) cannot be reformed to original configuration, see WP 0013 for replacement.

2. Replace all authorized unserviceable items. Retest all replaced parts.
