If, or when, fouling should become heavy, it can be
removed with a brass bore brush. Dip or spray the
brush with nitro solvent and scrub the chamber
and bore until the fouling is removed. To prevent
brass bristles from breaking off, the brush should
be pushed completely through the barrel before
being withdrawn.
NoTICe! do not use a stainless steel brush

To maintain the utmost accuracy of your rifle it is
recommended you clean the bore with a copper
solvent. Modern bullet jackets are made mainly of
copper. Residues from copper bullet jackets stick to
the barrel and require more frequent cleaning. Swab
the bore of your rifle with a good copper solvent using
the manufacturer’s recommended procedure.
3. After all fouling has been removed, the chamber and
bore should be wiped dry. When the bore is dry, pass a
slightly oiled patch through it for preservation. A fine,
light gun oil is recommended.
4. Inspect the barrel and chamber to be certain no
patches have inadvertently been left in them. Remove
any that remain.
5. Use a small brush or rag to remove dirt and foreign
matter from inside the receiver and other parts of the
action. Lightly lubricate all moving parts with a high-
quality, light gun oil. Use oil sparingly, a very light
film is sufficient. A fine, light gun oil is ideally suited
for this purpose.
6. Wipe all exposed metal surfaces with a lightly oiled
cloth making certain that all finger marks are
removed. Finger marks provide a place where moisture
can accumulate. The metal of the firearm should
receive a light film of oil any time the rifle has been
exposed to weather or handling.

The trigger mechanism has been adjusted at the factory to
provide a short, crisp pull consistent with safety and
reliability. The trigger is a single-stage design with the
weight of pull holding closely to four pounds. It is
recommended that no attempt be made to change the
weight of pull of the trigger.
This procedure should rarely, if ever, need to be
performed. However, if the receiver area of your rifle
should become excessively dirty or submerged in water it
may be helpful to remove the trigger group and expose the
inner cavity of the receiver for cleaning.
