To install "B-21U handguard" rail on a weapon, you need to:
1. Make an incomplete disassembly of the weapon and remove the regular handguard.
2. Install the "B-21U handguard" instead of the regular handguard. B-21U should be installed very rigidly, for that it is necessary to:
- install the regular handguard retailer on B-21U;
- attach B-21U to the receiver;
- place a wooden or metal spacer on handguard retainer, hammer in B-21U rail into the receiver of the weapon;
- close the lever on handguard retainer.
3. Assemble the rifle.

The hardness of the handguard landing determines the hardness of the landing of the sights, which affects the accuracy of the shot.
