Hold the scope and look through the eye piece at a flat, featureless well lit
area. The reticle should appear sharp and well defined. To make adjustments
rotate the ocular bell focus in either direction. Look through the scope again.
If the focus of the reticle has improved but is not perfect, continue to rotate in
the same direction. If the condition has worsened you will need to rotate the
bell in the opposite direction.
CAUTION:
BE SURE THAT THE FIREARM IS NOT LOADED.
PRACTICE SAFE FIREARM HANDLING AT ALL TIMES.
2.) MOUNTING
Catseye™ scopes have a one-inch tube diameter. Depending on your rifle you
will need to purchase the correct base dimension to insure fitment of mount
and rail. Using a rest or gun vise is highly recommended. (One piece or two
piece mounting rings can be used.)
• Separate the upper and lower halves of your ring(s).
• Install the lower half of your ring(s) on the rifle rail.
• Set the scope in the cradle.
• Replace the tops loosely (do not tighten).
Position the scope as far forward as possible and rotate the elevation turret
to be vertical. Slowly pull the scope backward until your full FOV (field of
view) is visible, check to make sure the reticle is aligned both vertically and
horizontally with the bore axes of the firearm.
Once properly positioned, tighten the top halves of your ring(s) mount using a
non-permanent thread lock.
CAUTION:
BE SURE THAT THE FIREARM IS NOT LOADED.
PRACTICE SAFE FIREARM HANDLING AT ALL TIMES.
3.) PRE-ZEROING
Locate an appropriate location to fire your rifle and set up a target at
a distance of 100 yards from your shooting location. You should use a
comfortable gun rest to eliminate as much human error as possible. Make
certain the rifle is empty with no cartridge in the chamber and the breech
open. Rotate the parallax ring to 100 yards. (CAT3510x50 parallax fixed 100
yards).
