NcSTAR STM3942GV2 - Manual (Page 7)

 IF YOU ARE NOT SURE ABOUT ANY OF THE PROCEDURES IN THIS MANUAL,
ALWAYS SEEK THE HELP OF A QUALIFIED PROFESSIONAL TO AVOID DAMAGE TO
YOUR SCOPE AND YOUR FIREARM.
CARE AND MAINTENANCE
Your Mark III Tactical Gen 2 scope is fog proof, shock proof, and waterproof. However, you
should never try to take it apart or clean it internally. The exposed optical lens surfaces will perform
their best if they are routinely cleaned with a lens brush and/or the lens cloth provided with your
scope.
For a deep cleaning, you can also use high grade camera lens paper and camera lens cleaning
solutions. Never use any other type of materials or solvents other than those designed specifically
for optical lenses to avoid damaging your scope. Clean the outer portion of the lens cavity first with
cotton swabs, clearing as much debris and dust as possible. Then, gently clean the lenses using a
circular motion starting in the center and ending at the edges. Do not rub the lenses continually;
simply wipe in short circular patterns.
Maintain the exterior surfaces of the scope by removing dirt or sand by using a soft brush or a
soft, dry cloth. You can also use a silicone treated cloth to restore luster and protect the scope
against corrosion. Be careful not to touch any part of the lenses with the silicone cloth.
It is not necessary to lubricate any part of the scope as all of the moving parts, such as the:
rheostat, turrets, and the Quick Focus Eyepiece, are permanently lubricated.
When not in use, always store your scope in a dry place with the lens caps on, to prevent
scratches to the lenses.
