should always be stored securely and
unloaded, away from children and careless

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...

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.
