Owner's Manual Supplement

1 Use a 2mm Allen wrench to loosen both the screws at the rib pivot

point, located at the junction of the rib and the barrel assembly

just above the front of the forearm (Figure 1). Only loosen the

screws enough to allow movement, as completely removing the

two screws could cause the loss of small parts contained in the rib

pivot point assembly.

FAILURE TO LOOSEN BOTH OF THESE SCREWS BEFORE ANY FURTHER

ADJUSTMENT CREATES A CONDITION IN WHICH THE RIB IS NOT

ALLOWED TO PIVOT OR MOVE VERTICALLY AND CAN RESULT IN BENDING

THE RIB.

2 The point of impact adjustment

is on the front end of the rib

and is adjusted by a spring

detent thumbscrew located

between the rib and the barrel

near the muzzle (Figure 2).

Turn the thumbscrew clockwise

to lower the front of the rib.

Turn the thumbscrew

counterclockwise to raise the

front of the rib.
