The biggest problem you'll have
with the bolt is that it's easy to put it
back together backwards. If you put
the cam actuator on wrong, you dam-
age the bolt. If you reverse the spring
guide and spring, you break the FriNg
pin.
Just remember th±s:
•
The long end of the fir±ng pin goes
±n the bolt first.
•
The small hole in the guide Fts on
the short end of the f±ring p±n.
•
The spring goes in the guide.

first, then the plunger¸ Put the sear in
so its humped end is up and to the rear.
The cover has a hinge pin and a hinge
pin latch. The pin must always go in
¹om the right, the latch fºom the left.
²f they're reversed, you'll bend the
cover and the gun will jam.

a round that's already chambered.
