hello ! I have bought a brand new Marui vsr-10! I've made a little Teflon mod at the bucking and a spacer mod for the barrel ! when I have no hop up at all sometimes a bb is rolling out of the barrel! like if I've put a little notch that's ok and no bb is rolling out! fps seem constant. So this is my question: do i need to worry about that or its normal ?????????? ( I've read that all g-spec have that kind of problem when no hop up is applied :/ just want to be sure that nothing was messed up when I've made those little modifications
