Alright guys i have a rather massive problem. I received a Hephaestus steel gas tube and recoilspring and rod. Installed a prowin cnc hop and prowin high out put valve and cut down bucking. My problem now is whenever i fire the first shot goes about 90 feet and the second or third will jam the gun in the 3/4 loaded position. After inspection of the bb it apears scarred on the sides which i had to mark in pink due to my garbage camera. Any ideas?
Actually i dont know how to post pics from my iphone so :/
