edition 1
Congratulations on buying this Pro Series Rifle scope.
10 years ago we started a company to provide optics designed by shooters
for shooters, with the back up that we as shooters would want. We wanted to
innovate, to reduce costs, to improve quality.
We think we have succeeded. Welcome to the MTC family.

Care and Maintenance
Your new MTC scope is a precision optical instrument, and while designed to cope with
the rigours of shooting on any calibre rifle, normal care must be taken, particularly of the
optical surfaces.
Clean the outer casing with a damp and soft cloth and then dry. Close the lens
protective cover at all times when the scope is not in use to protect the lenses. First
lens cleaning should always be with an optical puffer followed by a clean soft brush.
When necessary clean the lenses ONLY with a lens cleaning cloth and lens cleaning
fluid suitable for photographic equipment. If you clean the lenses with an abrasive cloth
such as a tissue, or have any dirt in the cloth, then your scope could well be damaged
beyond repair. Store the scope in dry, well-ventilated place.
Zeroing your rifle
On Mamba Pro - remove the turret
covers and store in a safe place.1 On
Viper Pro unlock both turret locks.2
Place a suitable target at 15 yards
(50 yards if you have a good
boresighter), ensuring a
suitable backstop.
Ensure the rifle is held steadily
and take 1 shot. Observe the bullet
strike. Use the Elevation Turret to move
the point of impact UP (anti-clockwise) or
DOWN (clockwise) and then the Windage Turret RIGHT
(anti-clockwise) or LEFT (clockwise). When point of impact
is in the centre of the target this can then be repeated at
progressively further ranges until the chosen zero range is reached.
Adjustment is ¼ MOA, that is one click move the point of impact ¼ inch at 100 yards.
When the rifle is almost zeroed start to fire groups of 5 shots before making small
adjustments. Remember that wind will affect the bullet flight so zeroing should be
carried out in calm conditions. When you are happy that your rifle is zeroed correctly
re-fit the turret covers (Mamba pro) or lock the turrets (Viper Pro).
The scope is supplied with magnetic flip-up covers that can be
moved to 4 positions as well as doubling up as a sunshade.
Covers can be removed by unscrewing of the scope tube or
can be adjusted to different positions and re-locked using
the knurled locking ring. Caution: on recoiling rifles do
not leave the rear flip up at 90 degrees as it could
move and cause injury.
Viper Pro set the rear flip vertically to use the
magnifying lens to view the turret markings.
Mamba Pro set the rear flip horizontally
to use the magnifying lens to view the
parallax markings.
SCB2 Reticule (MIL)
SCB2 stands for Small Calibre Ballistic Reticle (type 2) but really
it is suitable for all types of firearms but is especially appropriate
for long range weapons as well as giving the detailed information
demanded by target shooters. The SCB2 is spaced using milliradian (mil) and is
set to use the international Mil standard of 3.6 inches at 100 yards. The reticle is ‘true’ at
10 magnification.
Additionally a half Mil aiming point is added for exact shot placement.

Mounting the scope:
The scope must be mounted using good quality 30mm diameter rings. These rings
should not be over-tightened or damage may result. When selecting rings, please
ensure that they are high enough to allow the scope objective lens to clear the rifle,
but not so high as to raise the eyepiece so making sighting difficult. Please do not use
poor quality mounts as they will cause misalignment and inaccuracy, MTC recommend
Blueprint or Sportsmatch mounts. We advise scope mounting using the following steps:
1. Attach the mounts to the rifle action where you estimate the optimum placement.
Fasten securely.
2. Split the mounts and place the scope on the lower half, attach the top half securely
but with enough slack to allow the scope to slide with gentle pressure.
3. Move the scope backward and forwards to see a clear sight picture, with no black
circle around the outside.
4. Rotate the scope until the reticule is vertical, use a vertical edge or plumb line
to assist you. This is a dark art, and requires experience. We recommend that if
necessary you get a second opinion off an experienced shooter. If your scope is
oriented incorrectly you will shoot sideways when not on the point of zero.
5. Tighten the scope. Do this holding the SMALL edge of the 1.5mm Allen key, if
you hold the large side you will over-torque the bolts and your scope will suffer. The
mounts should show a crack between top and bottom equal on both side.
6. When you are happy that the scope is mounted perfectly tighten each Allen bolt
1/8th of a turn using the long edge.
Diopter adjustment
This obtains the sharpest Reticule image, and MUST be carried out first. This
adjustment only needs to be carried out once and is unique to each user’s eye. Rotate
fast focus ring to get the sharpest possible reticule. Hint: Don’t look at the Reticule for
more than a few seconds at a time as your eye will compensate for less than perfect
sharpness. Look away and look back again. Repeat until as sharp as possible.
Focusing / Parallax adjustment
The range for which the picture is in focus is called depth of field. This decreases with
magnification but increases with range. The centre of this focus is called the parallax
setting. For example, on x10 with a parallax setting of 26 metres the scope will be in
focus from about 14m to 35m, a depth of field of 21m. Focus the sight on the target
using the side focusing ring. This is also called parallax adjustment. Never try to zero
without a perfectly clear picture as aiming errors will occur due to parallax error.
Windage & elevation turret operation
Access to the adjustment is gained by removing the covering caps on the Mamba Pro
and by unlocking the target turrets on the Viper Pro. The adjusters are finger adjustable.
The bullet strike is marked with up/ down (top turret) and left/right (side turret), i.e. if you
want the bullet to go higher, turn anti-clockwise in the direction marked “up”. Replace the
turret caps on Mamba pro or secure the turrets using the turret lock lever on Viper Pro.
The centre part of the reticle can be illuminated to a help with accurate target
acquisition. Just the centre part is illuminated so as to avoid ‘washing out’ the lenses
inside the scope with too much light.
The illuminated reticule is turned on by a long press of the centre button located in the
middle of the parallax adjusting knob. The light intensity adjusts in six stages. A long
press switches the illumination off. Switching the illumination back on again will restore
the previous light intensity setting.
Battery can be changed by unscrewing the outer knurled cover on the parallax
assemble. Battery type is a CR2032. At night your pupils are open and it is not
recommended to use the illuminated reticule (IR) on high settings, these are for daylight
shooting in shadow. As the light falls you should turn down the illumination, using the
minimum necessary.
Mamba Pro turrets1
After zeroing the Mamba pro turret ring can be realigned
for reference.
Viper Pro turrets2
After zeroing, the printed numbers on the turrets
can be realigned: loosen the three 1.5mm Allen key
screws that are positioned at 120 degrees, lift and
turn the turret to re-align the 0 marking with the
arrow mark - replace the three Allen screws.
The elevation (top) turret also features a range window
behind which a range tape can be applied once the top
turret screws and turret are removed.
Range Tape (Viper Pro)
A range tape measuring 90x7mm can be affixed to the elevation drum after its removal
