Madbull ultiamte hopup, double feeding issues
I have a madbull ultimate hopup, with a guarder clear rubber, and a Mad Bull 6.01mm Ultimate Tightbore Barrel. theres no fitting issues in the hopup itself. I used a water based lube to assemble it, and its all lined up properly. At first I thought the hop was set too low, but even at its max setting its double feeding.
Im also having troubles getting mags to sit properly.
