So I've got the ir hop all set, but 1 out of every 10 shots the bb curves drastically to the side (flier), but every other shot besides the flier is perfectly on line. Setup: JG BAR 10 PDI VSR 10 Hop up Chamber Prometheus 6.03 Lonex 70 Degree Bucking IR Hop Z Kit I think this may be the due to the ir hop moving around since it's not permanently fixed with CA glue on the window, but I don't want to do that yet before figuring out exactly what the problem is. Also, although my shots are flatter and more consistent, I'm not getting as much over-hop range as I did with a regular bucking. the PDI chamber uses 2 o rings to press down both arms, and since the ir hop is significantly harder to press, the arms don't go down all the way, resulting in less maximum hop. Right now I'm thinking about a thicker nub, but not quite sure what to use for it. I should also mention that it appears my FPS has decreased. Max range with ir hop: 230 ft, 9/10 consistency. Max range without ir hop: 260 ft, 5/10 consistency. Any solutions to some of these problems are greatly appreciated.
