LEVELING YOUR RETICLE
With the scope mounted onto your firearm, you may have to adjust the scope in the three rail
mounting system to be plumb and level with the firearm.
If you have to adjust the scope, secure the rifle in a rifle rest, making sure the firearm is plumb and
level in the rifle rest. The use of a torpedo or bubble level can help with leveling the firearm and the
scope’s reticle.
To adjust the scope inside the three rail mount, you will have to loosen all the Allen head bolt screws
securing the upper rail mount from the lower base mount. With all the screws loosened, turn the
scope until the reticle is plumb and level with the firearm. The three rail mount has enough
clearance to allow the scope to be turned in either direction to help with leveling the reticle. When
you have the scope properly leveled you can tighten each screw evenly until the scope is securely
mounted inside the upper and lower three rail mount.
FOCUSING YOUR SCOPE
Your 3-Rail Sighting System Scope is equipped with a Fast Focus eyepiece on the rear of the ocular
lens easily distinguished by the serrated ring (Fig. 4). Once your scope is properly mounted you can
focus your reticle to ensure a clear and crisp image.
Figure 4
1. Hold your firearm and look through your scope in a
comfortable position to where you can see a full
field of view through the scope.
2. Make quick glances through the eyepiece at a
featureless, flatly lit area such as a wall or open
sky.
3. Spinning the eyepiece counter-clockwise will extend the eyepiece outward (generally suitable
for those who are far sighted). Spinning the eyepiece clockwise will bring the eyepiece back
into the ocular lens housing (generally suitable for those who are near sighted)
4. Fine tune your adjustments until the reticle appears clear and sharp. Once the eyepiece
reaches the outer limits of adjustment, be sure not to force it so as not to ruin the integrity of
the seals.
