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
The TW4x30 Tactical Weapon™ scope comes equipped with standard 2 piece
weaver mounts, an SKS mount and an AR style carry handle mount.
Weaver Mounts: Separate the top and bottom halves of the rings. Pre-install
the bottom halves. Set the scope in the cradles formed by the bottom ring
halves. Position the scope toward the objective lens. Rotate the scope to
position the elevation turret on top (at 12 o’clock). With the firearm in a
steady rest position (while looking though the scope), slowly pull it close
to the eye until the full field of view becomes visible. Check the orientation
of the reticle. The vertical post of the reticle can be aligned with the corner
of a wall, a light post, or the vertical axis of the rifle if an optical collimator
is not available. Misalignment of the reticle will not affect accuracy at short
distances but can become a problem at long distances.
AR Mount: The TW4x30 Tactical Weapon™ scope includes an AR style carry
handle upper receiver mount. Once the mount is installed the weaver rings
will install on top of the mount.
• Remove the threaded thumb screw.
• Position the extended threaded screw through the hole on top of your
AR handle.
• The threaded thumb screw is then reinstalled beneath the base of the
handle.
• Turn threaded thumb screw clockwise to tighten.
• Proceed to Weaver Mounts listed above. Check to make sure the reticle
is aligned both vertically and horizontally with the bore axes of the
firearm.
SKS Mount: Installing an SKS cover/mount should be done by a professional
gunsmith with knowledge of the SKS rifles and their tolerance variances.
Make sure your firearm is unloaded, then close the bolt. Pull the rear cover
retainer pin upward and outward until the retainer pin engages the slot and
pull the pin outward. The retainer pin will not pull all the way out. Remove the
rear cover with a rearward pull.
INSTALLATION: Install your new cover/mount by pushing it forward on the
receiver until the front forks engage the receiver. Push hard forward until the
