Manual

NOTE: An extremely dirty gas cylinder and gas piston may require
forcefully moving the gas piston forward with a hammer and soft
drive punch. Extreme care must be used to avoid scoring parts. If the
gas piston will not move with moderate force, place a couple of drops
of nitro-solvent around the gas piston, wait about 15 minutes, and
then try to push the piston out with the drive punch. If the piston
still will not move, apply more nitro-solvent on the piston and allow
it to set overnight before attempting to remove it.
6 Remove the inertia block, action spring, and action spring guide:
Tightly grip by hand the rear portion of the action and action spring
guide and pull forward toward gas cylinder until the action spring
guide is clear of its
recess in the receiv-
er. The rear end of
the action spring
guide can then be
moved to one side
of the receiver and
then rearward to
remove the action
spring, action
spring guide, and
inertia block. (See Figure 14.)
The gas cylinder can now be examined for accumulations of residue.
Residues in the gas cylinder and on the gas piston should be thor-
oughly removed with a good quality powder solvent or bore cleaner.
If residues are heavy, they can be removed by scrubbing the gas
cylinder with a 20 gauge shotgun bronze wire bore brush and a good
solvent.
NOTE: the gas cylinder screw located on the gas cylinder is set at the
factory.
DO NOT CHANGE THE SETTING ON THE GAS CYLINDER SCREW.
Any changes to the gas cylinder screw may adversely affect the
accuracy and operation of your rifle.
