  • To install the "B-21M handguard" rail on weapon, you need to:
    1. Make an incomplete disassembly of the weapon and remove the regular handguard.
    2. Install the "B-21M handguard" instead of the regular handguard. B-21M should be installed very rigidly, for that it is necessary to:
    - install the regular handguard retailer on B-21M;
    - attach B-21M to the receiver;
    - place a wooden or metal spacer on handguard retainer, hammer in B-21M rail into the receiver of the weapon;
    - close the lever on handguard retainer.
    3. Assemble the rifle.
    Attention! Do not file the handguard during installation. This can lead to the formation of a backlash at the junction of the handguard with the receiver.
    The hardness of the handguard landing determines the hardness of the landing of the sights, which affects the accuracy of the shot.

    The warranty period for the product is 60 months.
