General Safety Information
W WARNING
Safety is the number one concern when working with firearms.
• Keep the muzzle pointed in a safe direction at all times.
• Never allow live ammunition to be brought into the maintenance/cleaning area.
• Verify that the firearm is unloaded and clear prior to performing any maintenance.
• Do not touch the trigger unless the procedure requires you to do so.
• Always wear safety glasses with side shields when performing maintenance.
Setting Up A Safe Work Place
Having a proper work area to install this kit will help ensure success and reduce the chance of
damaging the firearm. A solid workbench with a bench mat, and a properly mounted vise with a mag
well block will help free up your hands for installation.

INSTALLATION
Mounting the TANGO6T riflescope to a SIG SAUER ALPHA Mount
Unscrew the mount screws with the provided T15 Torx tool and remove the mount ring top caps.
Place the riflescope inside of the mount and reinstall the top caps. Tighten the mount screws to finger
tight. You will adjust these fasteners again later.

8.
8
Place the riflescope on top of the desired weapons system. Set your
approximate eye relief by moving the mount forward or backwards in
different Picatinny slots. Optimal eye relief is 3.8” for the 1-6x24MM
scope. This is the distance from the ocular lens to the shooters eye.
Applying light pressure forward and to the left on your mount, tighten
the 1/2” hex bolts to 1/4 turn past hand-tight or 65 in-lbs.
Now you can slide the scope forwards and backwards inside of the
mount to set your fine or final eye relief.
A. Level your riflescope inside of your mount with the reference line
located on the front lefthand side of the maintube. This reference line
matches up with the top of the mount base.
B. The four screws which hold the mount top cap together should be
tightened in an ‘X’ pattern using the provided T15 Torx wrench. Take
care to make sure the gaps on either side are kept even, the screws
should be finger tight plus a 1/8 turn or 25 in-lbs.

OPERATION
Installing the battery
TANGO6T riflescopes are equipped with illuminated reticles and require CR2032 batteries. To install the
battery loosen the battery cap on the left side of the riflescope turret. Place the battery into the battery
compartment with the plus side facing outward. Screw the battery cap down snug to ensure optimal
sealing of the battery compartment.

Illumination brightness settings
• Pull illumination lock ring out to change brightness settings
• Select the illumination brightness level that suits your conditions the best
• Higher power settings are better suited for brighter conditions
• Lower power settings are better suited for low light conditions
• Brightness level settings alternate between on and off locations
• NV2 is the brightest Night Vision setting, with NV1 being the lowest Night Vision setting
• Push illumination lock ring back in to lock

SIGHT ADJUSTMENTS
Focusing the reticle with the Diopter Adjustment Ring
Aim the riflescope at a light object or wall to maximize the contrast of the
reticle. Turn the diopter until the reticle comes into focus.
Adjusting Power
TANGO6T riflescopes are variable power. In order to increase the power
setting rotate the power selector ring clockwise. Turn the power selector
ring until the image is magnified to the desired range.

12.
12
Installing the throw lever
Loosen the set screw on the provided throw lever. Slide it over the eyepiece onto the middle of the
Power Select Ring. Tighten the 2MM Hex to 5 in-lbs.

13.

Bore sighting
With the rifle in a firm rest, remove the bolt from your rifles action (with AR style rifles remove the rifles
upper from its lower assembly and remove the bolt carrier). Look through the rifles barrel from the rear
of the rifle and aim it so that your target is centered inside of the barrel. Without moving the position of
the barrel, use the elevation and windage adjustments of your riflescopes reticle so that it is also in the
center of the target.

14.
14
Point of Impact (POI) corrections
POI corrections should be done using the center of a three shot group. If you are not able to get a
consistent three shot group then you will need to further troubleshoot your firearm.
If your POI is located to the left of your point of aim (POA), you will need to adjust the windage to the
right. To move the POI to the right turn the windage adjustment dial counter-clockwise. To move the POI
to the left turn the windage adjustment dial clockwise.
If your POI is located below your POA you will need to adjust the elevation adjustment dial up. To move
the POI up you will need to turn the elevation adjustment dial counter-clockwise. To move the POI down
you will need to turn the elevation adjustment dial clockwise.
Once your POI is located where you want it in relation to your POA you can remove your adjustment dials
and reset them to zero. Once you have reset your zero you can put the caps back on your adjustments.

15.

sigsauer.com
Resetting the Zero of your adjustment dials
Both the elevation and windage adjustment dials of TANGO6T riflescopes
are able to be zeroed. This is done by loosening the 2MM set screw on
the top of each dial. Remove the dial from the scope and rotate it until
the 0 marker lines up with the adjustment indicator line. Tighten the
2MM set screw on the top of the dial to 6 in-lbs. Take caution during this
zero reset procedure not to rotate the actual adjustment settings as this
will shift your desired POI.

MAINTENANCE
Your SIG SAUER riflescope requires very low maintenance.
• If your riflescope came with an illuminated reticle make sure that you turn the illumination control to
one of the off positions when it is not in use.
• If the battery for your illuminated reticle is dead, replace it by rotating the illumination battery cap
counter-clockwise. Replace the battery with a new CR2032 battery positive side facing out.
• Keep your lenses clear by using a soft cloth or lens pen. The best way to maintain image quality is by
keeping your lenses clear of dirt and dust that cause scratches.
