CARE AND CLEANING
A firearm must be free of rust, dirt, grease and firing residues to function safely
and reliably. Periodic maintenance, which includes inspection of components to
determine if they are in proper working order, is absolutely essential. Firing
deposits particles of bullet lubricant and powder in the bore, chamber, bolt,
receiver, magazine and other parts of the rifle. There is no fixed rule as to how
frequently the cleaning should be carried out, but the alert gun owner soon
learns...

6. If the rifle is to be stored for an extended period, clean the rifle thoroughly.
Disassemble to the extent described elsewhere in this manual, taking care to
put pins and similar easily mislaid and “rolling” components in a tray. Rewipe
all surfaces with preservative oil. Reassemble and store properly.
STORAGE

MAINTENANCE OF
STAINLESS STEEL RIFLES
Firearms and components made of stainless steel are relatively more resistant to
corrosion than those of blued steel. However, in the interest of proper operation
and long life of a stainless steel firearm, inspect it frequently and clean, lubricate

Sometimes discoloration occurs from perspiration or from contact with some
types of gun cases. Rusting may occur as a result of the firearm being exposed to
moisture, salt air...

External surfaces most subject to rusting from handling, or from exposure to the
elements should be cleaned and wiped dry after use or after exposure to adverse
conditions. If the rifle is to be stored, coat it with a light film of oil or
preservative. Where the rifle is in continuing use, and the presence of oil or
grease would be objectionable, then the external surfaces can be coated (after
cleaning and drying) with a paste wax formulated for use on metals. Apply the
wax sparingly, allow time for...

the sight can be moved. Place a short brass rod against the sight base (and only
the base) and tap the sight in the direction you wish to move the point of impact,
then tighten the slotted screw.
NOTE:The ‘rule’ of rear sight adjustment is: Move the sight in the direction
that you want the point of impact of the bullet to move. As examples, to raise the
point of bullet impact, raise the elevation slide (blade). To move the point of
bullet impact to the right, move the sight to the right.
