3X-C™ Magnifier User manual
3X-C™ Magnifier
User manual
The Aimpoint® 3X-C Magnifying module can be used in conjunction with all
Aimpoint sights for long-range aiming or observing. A variable (-2 to +2)
dioptric setting allows this magnifier to be adapted to the individual shooter’s
eye. The Aimpoint 3X-C can also be used as a handheld 3X monocular.
Aimpoint magnifiers utilize the red dot in Aimpoint sights as the aiming reticle,
eliminating the need for re-zeroing when shifting between non-magnified and
magnified aiming.
The Aimpoint 3X-C is encased in a shock absorbing protective rubber cover
that also creates an ideal ergonomic grip. Internal optical adjustments make
the aligning of the magnifier and sight quick and easy.
For quick attachment/detach, we recommend the use of the Aimpoint
FlipMount or the Aimpoint TwistMount.

WARNING: Ensure the weapon is not loaded and the safety selector is in the
”safe” position before attempting to install, remove or perform maintenance
on the 3X-C - other than attaching/detaching it under normal use.
2.1 Installing the Aimpoint® 3X-C on a weapon
The mounting surface (3) of the 3X-C allow for mounting to any 30 mm
diameter ring mount. Follow the manufacturer’s instructions when installing
the 3X-C.
For quick attachment/detach, we recommend the Aimpoint FlipMount or the
Aimpoint TwistMount as shown in Fig. 2.

Aimpoint® TwistMount
The height of the mount is correct when the optical axis of the 3X-C and
the Aimpoint sight coincide. Select a suitable position for the 3X-C on the
weapon base so the eye relief is correct and feels comfortable.
Assemble the 3X-C to the chosen mount and install it on the weapon. The
3X-C shall be mounted with the Aimpoint logo to the left.
Carefully tighten the mount to the weapon base and retighten after a few
NOTE: Any adjustments (see “2.2 Centering”) of the 3X-C does not affect
the point of impact.

2.2 Centering
The 3X-C does not need to be zeroed. However, an Aimpoint sight used
together with the 3X-C must be zeroed so the red dot of the sight creates the
correct point of impact.
The 3X-C has two screws (1) that allow the user to center the red dot of the
Aimpoint sight when viewed through the 3X-C. Centering the dot inside the
3X-C is not necessary, but creates a more natural feel.
CAUTION: Do not continue to adjust the screws if you encounter resistance.

2.3 Diopter setting
Additionally, on the 3X-C it is possible to adjust the diopter setting by rotating
the diopter ring (2) as shown in Fig. 4.

Use in extreme heat or cold, salt air, sea spray, water, mud and snow, dust
and sand storms or high altitudes does not require any special procedures.
To reach maximum protection level for all weather conditions, wax is added
into the rubber mixture. The wax is slowly migrating to the surface of the part.
The wax is used up completely during frequent use and is not noticed by the
user. For long time storage, the wax is not used up as frequently and is seen
as a grey film on the surface. Wipe with a damp cloth to restore to its original
CAUTION: Never clean the lenses with the fingers. Use a lens paper/cloth.
If no lens paper/cloth is available, simply blow away the dirt or fog up the
lenses and dry them with a clean and soft piece of cloth.
