REASSEMBLY
33. Reassemble the bolt assembly as follows:
a. Install the bolt rings onto the bolt taking
care not to distort the new rings. To
install the bolt rings, see Figure 3-2-35
and proceed as follows:
(1) Carefully position one end of the
bolt ring in the bolt groove and hold
in place;
(2) Gently guide the circumference of
the bolt ring into the groove until it
snaps into position;
(3) Repeat for the other two bolt rings;
and
(4) Stagger the gaps in the bolt rings, creating a labyrinth sealing effect, to reduce gas
loss during operation.
b. Install the ejector as follows:
(1) With the bolt adequately supported, start the ejector retaining pin into its hole, being
careful to leave clearance for installing the ejector;
(2) Position the ejector spring and ejector in the bolt;
(3) Depress the ejector to compress the ejector spring; and
(4) Secure it with the ejector pin, ensuring that the ends of the pin are flush or below the
outer surface of the bolt body.
