3.1.4 CLAMPING DEVICE ADjUSTMENT
To adjust the mount clamping device, do the following:
1. Remove the CO-LR from the weapon.
2. With the clamping device unlocked (as shown in Figure 3-7), push the cam (B) towards the arrow,
which will cause the nut (A) to slide out of its hollow.
3. To tighten/ loosen the clamping device, push down on the cam (B) and turn the nut (A) CW/ CCW
respectively, in one-two increments (see note below). Much like when the cam (B) is released, back-
ward-moving springs will cause the nut (A) to slide back into its hollow.
NOTE :
The eight-sided nuts of the mount lever-cam locks will only fit into their hollows if turned in one
of the discrete positions using increments equal to 360°/8.
4. Verify that the adjusted lever-cam lock holds the weapon/ FSRS mounting rail firmly.
5. Repeat the procedure to adjust the clamping device’s second lever-cam lock.
