5. Be extremely careful to leave the safety in the interme-
diate position.
6. It is not necessary or recommended that you disassem-
ble the firing pin assembly further than this
(See Figure 18).
7. Carefully wipe clean and very lightly oil the assembly.
Aerosol lubricants are excellent for forcing out any dirt,
grit or moisture.
REASSEMBLY —
1. Screw the firing pin assembly back into the breech bolt
until the breech bolt sleeve lock engages the notch in the
breech bolt.
2. Reinsert the bolt into the receiver as explained previ-
ously.
IMPORTANT: Should the safety be inadvertently put in
the forward (fire) position with the firing pin removed,
the firing pin will be released forward and locked in the
forward position. This makes reassembling the firing pin
into the breech bolt somewhat more difficult.
As the breech bolt sleeve/firing pin assembly is screwed
back into the breech bolt the cocking ramp of the firing
pin must compress then uncompress several times before
the assembly is fully screwed in. Place the breech bolt on
a flat hard surface and using the breech bolt handle and
the head of the bolt as a support, firmly turn the breech
bolt sleeve clockwise until it snaps into position. Once
the bolt assembly is installed in the action and the bolt
closed and cycled, the firing pin will recock, and the safe-
ty can be moved back to the intermediate or rear position.
SIGHT ADJUSTMENTS
Some Model 70 rifles are fitted with open sights. The
style and adjustment system may vary between models
and grades. The proper procedure is to shoot a group with
the sights set as they come from the factory (intermediate
position on both elevation and windage), and then make
