Simply tighten the barrel nut, attach the handguard, and tighten the six fixing screws on the left, right, and bottom.
The handguard automatically fits tightly against the receiver.

Basically, there is no need to insert a shim between the handguard and the outer barrel flange.

The included screw is a special item with a tapered tip.
The short screw coated with green locking agent is on the receiver side,
The long screw coated with blue anti-loosening agent faces the muzzle.

*Because these screws are special, it is difficult to find a replacement.
Please keep the spare screws provided in a safe place.

Tighten the barrel nut with just enough torque so that it does not loosen and the receiver does not crack.
The included wrench is made of 3D printed resin, so if you are concerned, please prepare a barrel wrench separately.



Once the handguard is attached, lightly tighten the screws in the order shown in the image above to align the orientation.
Next, tighten them in the same order, applying a torque of 1.6 to 1.8 N·m.
