Windage and Elevation Adjustments
The Spitfire incorporates elevation and windage dials with audible
clicks. Each small click will move the point of impact 1/2 Minute of
Angle (MOA). 1/2 MOA will closely correspond to 1/8 inch at 25 yards,
1/4 inch at 50 yards, 1/2 inch at 100 yards and 1 inch at 200 yards.
Adjust the settings
• Remove the dial covers.
• Use a coin or screwdriver to make the adjustments.
• Turn the adjustment dial in the appropriate direction as indicated
by the arrows. Move the dials in the direction you wish the bullet’s
point-of-impact to change.
Example
At a 50 yard sight-in distance, it will take four clicks of the dial to move the
bullet’s point-of-impact one inch.
Elevation Windage
Mounting the Spitfire
Orient the Spitfire so the illumination dial faces shooter.
1. Loosen the two base
clamp hex nuts and
attach the Spitfire to the
rail/base, making sure
that recoil lugs are solidly
seated in base grooves.
2. Checking that the
mount fully engages the
base, press the Spitfire
down and forward, then
tighten and torque the
base clamp hex nuts.
Recommended Torque
Base Clamp Hex Nuts 35–45 in/lbs
Mount Heights
The Spitfire comes from the factory with a mounted height of 40.4 mm
from the optic center to base surface. This is commonly referred to as a
lower 1/3 co-witness height. If a lower 30 mm mounted height is desired,
loosen the two mount screws then remove the base clamp and mount riser.
Remove the mount riser and reinstall the base clamp with the shorter
mount screws provided in the box using a non-permanent thread-locking
compound when installing the screws.
Note: To prevent recoil injury, position it so that you have at least two
inches of eye relief once the Spitfire scope is attached. Be sure you can see
the full field of view through the scope before tightening down the mount.
Rotate the adjustment dial in the
direction you wish the bullet’s
point-of-impact to change. For
example, turning the turret
counter-clockwise will move the
point-of-impact up or to the right.
