Step 4. Check for looseness between Tower Portion (5) and Tube Portion (6). If looseness exists, notify Direct Support Maintenance.
Step 5. Insufficient gas pressure. Check for caked carbon in Inlets (7) and Outlet (8) of Gas Regulator (9). Clean as required.
NOTE
DO NOT lubricate Gas Regulator (9).
Step 6. Check for binding of Slide Assembly (10) in receiver. If binding occurs, check for improperly assembled Firing Pin Retaining Pin (11). The firing pin retaining pin must be flush or below the body of the slide assembly on the left side of the slide. See maintenance instructions for slide assembly.
NOTE
If the Firing Pin Retaining Pin (11) is not flush or below the surface of the body, it can interfere with the internal rail of the receiver. It will drag on the rail and slow the functioning.

A loose fit between the cocking handle assembly and the receiver can cause an override condition (failure to charge malfunction). The malfunction is characterized by the Cocking Handle Arm (1) overriding the Slide Assembly (3) and slipping behind the Roller
Assembly (2).

2. FAILURE TO CHARGE (Cont).
NOTE
Several conditions can cause extreme looseness between the cocking handle assembly and the receiver. Looseness should be diagnosed in the following order:
a. Check the upper rail of the Cocking Handle Channel (4) for a bulge just rear of the Cocking Handle Stop (5). If this condition exists, notify Direct Support Maintenance.
b. Check the Cocking Handle Channel (4) for separation from Receiver (6).
NOTE
Separation generally occurs in the cut-out area just rear of the Cocking Handle Stop (5). If this condition exists, notify Direct Support Maintenance.

c. Check for cracks in areas indicated with arrows (around the Retaining Pin Holes and the radii of Cocking Handle Channel). If cracks exist, notify Direct Support Maintenance.
d. Check for bent Arm (8) on Cocking Handle Assembly (9). If bent, notify Direct Support Maintenance. Check cocking handle assembly for wear of the Feet (10) that travel inside the rails of the Cocking Handle Channel (4). Wear is difficult to determine, since the feet are internal to the channel. However, if the channel is not bulged or separated, wear on the feet of the cocking handle can be assumed and Direct Support Maintenance should be notified.

3. FAILURE TO FEED/STRIP.
Step 1 - Insufficient gas pressure. Check for caked carbon in Inlets (1), Outlet (2) of Gas Regulator (3). Clean as required.
Step 2. Check Feed Tray (4) for cracks, damaged or loose Rivets (5), and gouges in area (6).
Check for damaged, weak or worn operating parts in Cover and Feed Mechanism Assembly (7). If defective, notify Direct Support Maintenance.
NOTE
Cover and Feed Mechanism Assembly (7) shown removed for clarity.
Step 3. Check for broken, improperly assembled, or missing Springs (8) under the Cartridge Guides (9).
If defective, notify Direct Support Maintenance.
NOTE
A fail to feed/strip can occur when the plastic feed strap of the 200 round magazine is not used and the operator incorrectly positions the first round of a partial belt on the feed tray.
Step 4. Check for damaged Driving Spring (10). Replace Driving Spring, if more than one broken strand is found on same coil or if more than two strands are broken regardless of location on entire spring.

4. FAILURE TO CHAMBER.
Step 1. Failure to chamber malfunction is characterized by a round of ammunition not fully seating in the barrel because the bolt rides under the round. The unchambered round usually exhibits a damaged/bent condition similar to the illustration.
Several conditions can cause the round to not fully chamber and should be diagnosed in the following order:
a. Check for a spent cartridge case in the bottom of the receiver which would not allow the bolt to fully chamber a round. If a spent cartridge is found in the bottom of the receiver, refer to failure to extract and failure to eject malfunction troubleshooting procedures.

6. FAILURE TO EXTRACT.
Step 1. Failure to extract malfunction is characterized by a spent cartridge case not clearing the chamber or clearing the chamber but not clearing the ejection port. If the spent
cartridge clears the chamber but does not clear the ejection port, it can cause a failure to chamber malfunction. The spent cartridge case usually exhibits the “crunched” condition similar to the illustration and can be found in the bottom of the receiver assembly.
