1. Partially disassemble the weapon and remove the stock fore-end.
2. Install the B-21M forend instead of the standard forend. The B-21M fore-end must be installed in its regular place in the groove of the weapon's receiver. For this it is necessary:
- install the standard fitting on the B-21M fore-end, Fig. 2, Pos. 1;
- align the free end of the B-21M forend with the groove of the receiver;
- put a wooden or metal spacer on the swivel washer, hammer the forend B-21M into the receiver of the weapon Fig.2 .;
- close the checkbox on the frame.
3. Assemble the weapon.
Attention! To install the B-21M forend into the receiver of the weapon, do not cut it with a file, because this can lead to the formation of a backlash at the junction of the forend with the receiver. The forend seating stiffness determines the seating firmness of the sights, which affects the accuracy of the shot.
