The Model 70 will function better and more reliably over
a longer period of time if it is properly maintained and
kept clean.
BEFORE PERFORMING ANY CLEANING PRO-
CEDURES, ALWAYS MAKE CERTAIN THERE
ARE NO CARTRIDGES IN THE CHAMBER,
MAGAZINE OR ACTION/FEED AREAS.
You should clean your Model 70 after every day of
shooting and more often if it becomes excessively dirty.
If shooting for extreme accuracy your Model 70 should
be cleaned after every 50 shots or even as few as every
25 shots under competitive conditions.
A minimum cleaning includes wiping down the action
and oiling key parts. Most regular maintenance will also
include cleaning the barrel. If you encounter a function
problem (tight action when working the bolt), be sure to
give your gun a thorough cleaning to see if it solves the
problem before seeking the services of our service facility
or a competent gunsmith.
To clean your firearm, follow the general outline below:
CLEANING PROCEDURES —
BE CERTAIN YOUR GUN’S CHAMBER AND
MAGAZINE ARE UNLOADED. ALWAYS WEAR
PROTECTIVE SAFETY GLASSES DURING
ALL CLEANING PROCEDURES. KEEP
AMMUNITION AWAY FROM THE CLEANING
AREA. DO NOT TEST THE FUNCTION OF
YOUR FIREARM WITH LIVE AMMUNITION.
Always place the safety in the intermediate “on” (safe)
position before beginning any cleaning procedure.
Remove the bolt from your rifle as explained previously.
1. Use a cleaning rod with a tip and patch suitable for the
caliber of your Model 70’s bore. Make sure the patch is
large enough for a snug fit in the bore. Insert the rod and
patch into the barrel at the receiver end and run it back
and forth several times. Use a crown protector if you are
cleaning from the muzzle end of the barrel. Damage to the
crown of a barrel can affect the accuracy of your rifle.
