Additional rear Basis on the bottom is especially convenient in combination with RL-1 hand stopper.

M5x7 screws8 pcs.
Manual1 pc.

M5х7 screws will be needed in case of installation of B-19, B-19N, B-22, B-33 rails. Do not use screws from the kits of those rails (M5x9) with B-10U! M5x9 screws are made for B-10M handguard, not for B-10U.

To install "B-10U 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-10U handguard" instead of the regular handguard. B-10U should be installed very rigidly, for that it is necessary to:
- install the regular handguard retailer on B-10U;
- attach B-10U to the receiver;
- place a wooden or metal spacer on handguard retainer, hammer in B-10U 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.
