Weight: -g
Material: Polymer/Metal
Capacity: 30 rounds (recommended)/(maximum 32 rounds)
*The actual capacity may vary slightly depending on the BB manufacturer's specifications.
*If used with an HFC134a (CFC gas) model, the muzzle velocity and power will significantly exceed the standard value (0.989J), which violates the revised Firearms and Swords Control Law. Therefore, absolutely do not use it with models designed for CFC gas.
*When inserting a CO2 cartridge, gas will escape momentarily, but the leakage will stop once the magazine tube cap is fully tightened.
