INSPECTION OF INSTALLED ITEMS/REPAIR

1. GENERAL.

a. Inspect the alignment guide while assembled. Do not disassemble unless parts replacement is necessary. Ensure the shoulder screw (1) and alignment guide flat spring (2) do not move relative to each other. It is permissible for the shoulder screw and flat head screw (3) to turn together as long as the alignment guide flat spring is not loose. Inspect shoulder screw and flat head screw for thread damage (4). If damaged, replace.

2. ALIGNMENT GUIDE FLAT SPRING.

a. Inspect the alignment guide flat spring for cracks. If cracked, replace. ASSEMBLY

1. POSITION ALIGNMENT GUIDE FLAT SPRING AND INSERT FLAT HEAD SCREW.

a. Position alignment guide flat spring (1) against the flat side of the alignment guide (2). Ensure the curved part of the flat spring fits the slot in the alignment guide and the pin holes are aligned. Apply sealing compound to the new flat head screw's threads. Insert the new flat head screw (3) through the holes in the alignment guide flat spring and alignment guide, as shown.

2. INSERT SHOULDER SCREW.

a. Insert new shoulder screw (4) over the tip of the flat head screw. Hold the flat head screw (3) in place using a 1/8 inch allen wrench. Tighten the shoulder screw fully, using the raised edge of the combination tool. No relative movement should exist. Stop tightening when the alignment guide flat spring (1) cannot be moved and when the flat head screw tip is about flush with the shoulder screw's head.

Staking the shoulder screw to the flat head screw is an additional precaution to prevent it from loosening during operations.

a. Use a center punch to stake the shoulder screw (4) in two places, 90 degrees to the slots.

4. INSTALL ALIGNMENT GUIDE ASSEMBLY.

a. Depress the tip of the alignment guide flat spring as you slide the alignment guide assembly into the forward part of the receiver. Ensure the large hole slides over the ogive plunger assembly and that the alignment guide assembly shoulder screw mates with the keyhole in the receiver.
