    Any ideas on how I can get my hop up adjusted. I have a metal hop up. No matter how much or less I adjust my hop up the bb goes straight up into the air. And I also have a mad bull bucking.

    What weight bbs are you using and did you shim your hop up arm?

    Are you sure the barrel and bucking are properly centered in the hop up?

    I use .25s. And I'm not sure about those questions because I had someone else to install my hop up for me. I had a rookie mistake my first try and tore my bucking.
