Hi!! I am watching your channel, and with the help of the automatic translation, I am having a good learning time!! thank you so much for sharing all of these informations you got here. In this country where I am, it is very very dificult to get a japanese replica beside some Tokyo Marui models, and maybe KSC. And to practice airsoft legally, it is another hard job. I have only a very old japanese replica, an electric Marushin's UZI, and I need parts for it, and I can not buy them. The others I own are WE-Techs, WELL, KWC, UMAREX, ARMY ARMEMENT, but no japanese's replicas 😧😧😧. This device you made, it is very good builded, and I wish i could see some detailed information , so some day I could try to make one, but I do not have the conditions to work. NOw I will continue to watch your channel, as it is very good, and it motivates me a lot!!!!
