【CZ75D・Co2ブローバック・シャーシの入れ替え・マグ分解組み立て】・55挺目⑦

To study the mysterious and rare CZ75D CO2 blowback, I transplanted most of the parts, including the chassis, from an S2S fixed gas gun. This solved the mystery of the trigger bar spring, and I believe I've restored it to its original state. #CZ75D #CO2 blowback # # # #airsoft #gbb #airsoftgame
