    Hi guys. I was wondering if you could give me some tips on how to repair my ZCI 509mm 6.02 R-hop tightbore barrel. Story is that BBs disperse everywhere even when I am firing in semi automatic. What would you think it's the problem? I took it to a repair shop and they said they "fixed it" when the dang thing still shoots like cràp. The people whom I bought it from won't even bother to answer the phone. So at the moment I feel screwed and I dont know what to do. Any tips/suggestions on what I could do to repair this supposed to be "awesome barrel"?

    Did you examine the hop up unit yet? I would also recommend doing a compression test at the hop up to air nozzle seal.

    I mean, it's done it through 2 rifles already. That's why I am concerned

    A few more details would be helpful.

    BB weight and brand?
    Hop up? Hop rubber? Nub? The model of gun?
    Have you cleaned the barrel?

    Yes. The barrel, I should of mentioned that its the drop in kit. I have used .25s and .30s KWA ammo. I has been used in a G&G M16A3 (GR16) And a DBoys M16A4. Both brand new.
