NcSTAR DRGB135 - Manual (Page 3)

MOUNTING PROCEDURE
Your optic’s 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 easy for the DRGB135, by including a 30mm Cantilever Mount (8) with the optic.
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 SIGHT OR FIREARM.
CAUTION: BE SURE THAT YOUR FIREARM IS UNLOADED AND POINTED IN A SAFE
DIRECTION. PRACTICE SAFE FIREARM HANDLING PROCEDURES AT ALL TIMES.
1. Begin by loosening the Mount Hex Nut (9) on the side of the mount. Using a wrench of the
appropriate size, turn the Mount Hex Nut on the Mount counter-clockwise to loosen the Rail
Clamp (10) from the mount.
2. After loosening the Mount Hex Nut (9), pull the Rail Clamp (10) away from the side of the mount.
This will allow you to place the Red/Green/Blue Dot directly onto the optics rail of your firearm.
Seat the Red/Green/Blue Dot sight onto the top of your firearm’s optics rail, with the objective
lens (Platinum coated lens) facing the muzzle. Make sure that the Mount Cross Bolt on the
bottom of the Mount fits securely into a cross slot on your firearm’s optics rail. Once you have
your sight positioned properly, turn the Mount Hex Nut (9) clockwise until the Rail Clamp (10)
secures the Red/Green/Blue Dot sight to the firearm’s optics rail. If you are using a wrench to
tighten the mount, be careful to not over-tighten the nut.
3. You have now successfully mounted your sight.
