form the following:
1. While pushing down on the lever holder (C), turn the lever (B) backwards to loosen the QRM clamp-
ing device (A).
2. Install the QRM on the weapon rail by inserting the stop (not shown in Figure 3-5) into one of trans-
verse slots of the weapon rail.
3. To secure the QRM onto the weapon rail, turn the lever (B) forward. Secure the clamping device (A)
tightly to the weapon rail. To adjust the force of the lever clamp, loosen or tighten the nut (D) as neces-
sary:
- When the clamping device (A) unlocked, push the lever holder (C) so that the nut (D) gets out of
its hollow.
- To tighten/loosen clamping device, turn the nut (D) CW/CCW, respectively, by one-two increments
(the eight-sided nuts of the AIM clamping devices fit their hollows only if turned in one of the dis-
crete positions), when the holder (C) pushed. Just as the holder (C) released, backmoving springs
makes the nut (D) get back into its hollow.
- Check to ensure the clamping device holds weapon/NVM rail firmly.
