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.
SUGGESTED SIGHT PICTURE
Top of front sight even with top of
rear sight slide. Front sight
centered in notch of rear sight
slide. Target bull’s-eye centered on
top of front sight.
SIGHT ADJUSTMENT
(For Standard Rifles Equipped With Open Sights)
The folding leaf rear sight is adjustable for elevation. The slide must be moved
one graduation to change the point of impact by approximately one inch at 25
yards. Shooting to determine the slide setting for ‘zero’ at a particular distance
should be done from a bench rest and over a measured distance. Use only a small
screwdriver with a blade tip that exactly fits the screw-head. Loosen the screws
only slightly so the slide doesn’t move too freely. Move the slide in the direction
you want the point of impact of the bullet to move. When the slide is positioned
at the desired height, carefully tighten both screws.
Lateral (windage) adjustment is made by “drifting” the sight base in its slot.
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.
