MAINTENANCE OF
STAINLESS STEEL COMPONENTS
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 surface 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.
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.

ATTACHING RUGER SCOPE RINGS
Each Ruger telescope ring is a mated assembly of a top and a base. Do not mix the
parts of the two ring assemblies as they are not interchangeable. On the underside
of each mounting ring assembly there is an integral lug, located off center with
respect to the front and back sides of the mount. The lug is nearer to the front
surface. By reference to the lug, the mounting ring can be correctly assembled with
the front of the ring toward the muzzle of the rifle.
1. Disassemble one ring and reassemble over the scope body between the turret and
the eyepiece. Remember - the lug on the base should be on the front side of the
scope.
2. Install the four top screws. Do not tighten.
3. Disassemble the other ring and install it on the forward section of the scope tube
with the lug forwardly also. Install the four top screws. Again, do not tighten.
4. Assemble the rings to the receiver with the lugs engaging the recesses in the top
surface of the receiver. Tighten the clamp nuts so that the rings are locked to the
semicircular cuts on the sides of the receiver.
5. Rotate the scope until cross-hairs are aligned properly and slide scope to desired
eye relief. Then tighten the eight top screws each a bit at a time to grip the scope
body.
6. Sight in according to the directions with your scope.
