After building my l129a1 and awaiting my r-hop patches, i put it together with a flat hop. sorbo flat nub and im getting left hooking shots cosistently. The nub is level when looking down the barrel and isnt twisted. Also noticed i have a full non ported cylinder with a 350mm barrel. Is this screwing with my accuracey? Also after each shot on semi my nozzle is left partly retracted, this is even with an Ab mosfet. confused to say the least.
