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
and apply an appropriate rust preventative.
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 or chemicals.
Minor discoloration can usually be removed by rubbing the stainless area with an
abrasive ink eraser, crocus cloth, or a “metal polishing” compound. When using
any of these abrasives, proceed with care and use light pressure to achieve a
blending of “color” with those areas that are not discolored. Do not use abrasives
on the clear coating of the aluminum alloy trigger housing.
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 it to dry hard, then buff lightly with a soft cloth.
When applying the wax, take care that it does not get into the mechanism or on
the functioning parts or in the bore.
SIGHT ADJUSTMENT
Shooting to determine the setting of the elevation slide (aperture) should be
done from a bench rest and over a measured distance.

The front sight is aligned in the
center of the rear sight aperture
(“peep”) and the target (bullseye) is
