5. Remove all four filler screws from the top of the
receiver using a very small, thin-bladed gunsmithing-
type screwdriver.
6. Pre-position the bases on the receiver top to
determine the best orientation of the bases. Most
bases have transverse grooves cut into them that are
offset from the middle. These are the grooves that the
crossbolts in your scope rings will pass through. The
grooves are offset to allow you to position the bases to
fit the design/length of your scope and the placement
of the scope front to back for proper eye relief. Place
both grooves to the rear, both to the front, or one
in each direction, depending on your scope and
desired position.
7. Once you know which configuration you will use,
insert the screws through the bases and screw them
into the receiver top using the correct wrench or
screwdriver (usually a 3 /
32
" hex wrench). You must
use screws which are at least 11 /
32
" in length to ensure
proper thread engagement.
Many gunsmiths find it helpful to use a drop of
serviceable thread locking compound to assure the
screws stay tight. Make sure the compound does not
get into the action. Be careful to assure that the
threads of each screw engage properly in the threads
in the receiver to prevent stripping the threads in the
alloy receiver.
8. Tighten the screws snugly, but do not overtighten.
9. Mount your scope rings and scope as outlined in the
instructions supplied with your scope rings and/or
scope. Always make sure you have the proper eye
relief. Always make sure that the saddle crossbolts
and the cap bolts on the rings are fully tightened
before using your shotgun.

fitting is required. However, some important restrictions
must be observed:
• Never use a barrel with a 3½" chamber on a shotgun
designed for barrels with a 3" chamber.

Some Super X3 shotguns are designed to accept a scope or
other optical sight; usually these are turkey and deer
models. The top of the receiver on some of these models
is drilled and tapped for scope bases. Other models are
equipped with a cantilever scope base. If your shotgun has
a cantilever mount, follow the mounting instructions
supplied with your scope rings and/or scope. If your
shotgun’s receiver is drilled and tapped for scope mounts,
four holes (in line, in pairs on top of the receiver) will be
visible. They are fitted with filler screws. If yours is drilled
and tapped you must adhere to the following:
