MOUNTING PROCEDURE
MOUNTING PROCEDURE
 
Your scope mount is the link between your firearm and your optics. It is very important 
to have a solid connection between the two in order to ensure proper function of all 
components. NcSTAR has made installation fast and easy for the Rubber Armored Mark 
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. 
 
CAUTION: CAREFULLY FOLLOW ALL OF THE MOUNTING PROCEDURES. 
FAILURE TO DO SO CAN CAUSE DAMAGE TO YOUR SCOPE OR FIREARM 
 
CAUTION: BE SURE THAT YOUR FIREARM IS UNLOADED AND POINTED 
IN A SAFE DIRECTION. PRACTICE SAFE FIREARM HANDLING 
PROCEDURES AT ALL TIMES.
