If I'm right, this is a local kid with the Masada, and the gun doc is me.

The A&K Masada is one of the worst gun designs I've seen, and there are almost no replacement parts for it, since it's a proprietary design. The hopup unit as it is probably doesn't even provide any hop effect, and the lever is so loose and poorly designed that the hopup nub can fall out. My best guess is that the nozzle isn't making a seal with the hopup rubber, but after testing with the outer barrel on, outer barrel off with just the hop unit and inner attached, pressing the hop unit into the mechbox manually at different angles, trying a new hop rubber, nothing helps.

I told him I don't know if that gun can be saved. He could try a new nozzle (if they even make any aftermarket ones), but I'm not sure if that would help. It could possibly just be a result of such poor tolerances that it doesn't work. I told him that he should avoid it, and he bought it anyway, used.
