Note: Screws М5х7 are intended for installation of brackets B- 19, B-19N and B-22 on the B-21L forearm. Do not use the screws from the set of the indicated brackets (М5х9) when installing on the B-21L! М5х9 are designed for the B-21M forend.

To install the B-21L forearm on the weapon, you need:

1. Partially disassemble the weapon and remove the stock fore-end.

2. Install the B-21L handguard instead of the standard forend. The B-21L fore-end must be installed in a regular place in the groove of the weapon's receiver, it is very hard for this:

- install a regular fit on the B-21L fore-end;

- align the free end of the B-21L forend with the groove of the receiver;

- put a wooden or metal spacer on the swivel washer, hammer the B-21L forend into the receiver of the weapon;

- close the checkbox on the dock.

3. Assemble the weapon.

Attention! To install the B-21U forend in 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 firmness of the forend determines the firmness of the landing of the sights, which affects the accuracy of the shot!
