Well, I know its not a tm but it is a vsr clone, so I thought it would be appropriate here. Anyway, in my bar-10 I have all Laylax internals (zero trigger, piston, spring guide, 170 spring, cylinder head, teflon cylinder, 6.03 barrel), a nineball bucking, and dangerwerx hop up arm. Now, after everything was installed, I took it out and shot and without hop-up it was getting around 135 feet, which I found under-impressive personally. I was having issues with the bolt cycle, so I spray silicon spray in the cylinder as well as soaked a #13 o-ring in silicon and then put it in. After, the bolt push was excellent, but now I'm getting probably about 80 feet of range with no hop-up on, and when I turn on hop-up I noticed nearly no difference. I believe from the start something was wrong. Any ideas? Could it be compression issues within my hop-up? I'm stumped at the moment.
