Lightweight Boltend Weight for CYMA CGS/TM/DE AR / M4 GBBR Gas Replicas [3DM]

The lightweight boltend weight for CYMA CGS AR / M4 GBBR gas replicas is a reduced-weight rear bolt carrier component designed for tuning and improving the operation of gas replicas with a blowback system. The part uses powder-based 3D printing, 12 g weight and compatibility with CYMA CGS, Double Eagle and Tokyo Marui gas replicas, supporting the configuration of the moving bolt carrier group in a GBBR replica. The set is intended for servicing and modifying the bolt carrier operation in gas replicas with confirmed compatibility.

Construction and design

The lightweight boltend weight replaces the original rear bolt carrier component. Its reduced-weight design lowers the mass of the moving part that operates during each firing cycle in a GBBR replica.

The element is made using powder-based 3D printing technology and comes in black. This construction helps reduce the weight of the part installed inside the bolt carrier group.

GBBR gas replica tuning

In a GBBR replica, gas is responsible for the movement of the bolt carrier group, the operating cycle and the blowback system. Reducing the weight of the rear bolt carrier component may support replica operation in lower temperatures or affect the rate of fire and gas efficiency in standard operating temperatures.

After installation, the manufacturer recommends cycling the replica several times and checking whether the mechanism operates smoothly. This check helps confirm that the part is seated correctly before further use.

Compatibility

The lightweight boltend weight is designed for CYMA CGS, Double Eagle and Tokyo Marui gas replicas.

Before installation, check the compatibility of the specific replica model and make sure the part is seated correctly inside the bolt carrier group.
