4. Verify that the clamping devices are firmly holding the mount. If

necessary, adjust each clamping device’s lever-cam lock as

detailed below:

1) Remove the QR mount from the rail.

2) With the clamping device unlocked, push the cam (D) towards

the arrow, which will cause the nut (E) to slide out of its hole.

3) To tighten/ loosen the clamping device, push down on the

cam (D) and turn the nut (E) CW/ CCW respectively, in one-two

increments (see note below). Much like when the cam (D) is

released, backward-moving spring will cause the nut (E) to

slide back into its hole.

NOTE:

The eight-sided nut of the mount lever-cam lock will only fit into

their hole if turned in one of the discrete positions, using increments

equal to 360°/8.

4) Verify that the adjusted lever-cams lock securely hold the

weapon mounting rail.

5. Remove all screw (F) along with the ring halves (G) and (H) (you

can remove the QR mount from the rail for convenience).

6. Place the scope between the halves of the rings and slightly fixing

it with the screws (F) only enough to allow the scope to rotate and

move back and forth.
