III Tactical Series by incorporating the Quick Release System. You should place your
firearm on a secure platform, such as a gun vise, before performing any of the following
procedures.

positioned properly close the Quick Release Lever once more. Now, tighten the
Set Screw until it is snug using the provided allen wrench.

3. At this point your scope and mount are in place, but they are not yet anchored to

the firearm solidly. Open the Quick Release Lever and make small adjustments to
the Set Screw. Open and close the Quick Release Lever checking the tightness of
the mount. Perform this action as many times as necessary until the mount is set
firmly atop the rail. CAUTION: It does not take a lot of force to get this unit
mounted securely. Be certain not to over tighten the Set Screw to avoid stripping
it. Damage can also occur to the Quick Release Lever if to much force is applied

mount connection by opening and closing the Quick Release Lever, you can now
tighten the Locking Nut to secure the adjustments you have made. Tighten the
Locking Nut with the Quick Release Lever in the closed position for best results.
Be sure not to over tighten the Locking Nut to avoid stripping it. You have now
successfully mounted your scope. By simply opening the Quick Release Lever
and pivoting the scope in the direction of the Locking Nut, you can easily remove
the scope from your firearm. Make a reference as to the position of the scope and
mount in relation to the rail so that eye relief settings may be retained.

FOCUSING YOUR SCOPE

Your Rubber Armored Mark III Tactical Scope is equipped with a Fast Focus eyepiece
on the rear of the ocular lens easily distinguished by the serrated rubber ring (Fig. 3).
Once your scope is properly mounted you can focus your reticle to ensure a clear and
crisp image.

1. Hold your firearm and look through your scope in a comfortable position to where
you see a full field of view.

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)
