CNC precision machining of carbon steel, weight 223g (original weight 202g zinc alloy injection manufacturing),
compared with the original more durable, an appropriate increase in the weight of the gun, without affecting the performance of the more enhanced recoil feedback and solidity,
the pull handle is not easy to break, the sound of metal strikes more crisp, the normal temperature of 25 ℃ test 8KG (134A) gas can be used normally, does not affect the performance.
