First off, I realize I just posted question (tracing bb's at night), but this is a completely different question that I need help answering.
I bought a PDI hop-up chamber for my L96. Its a great looking peice of work. My only problem with it, I can't seem to turn the hop-up 'off.' I have screwed the screws in to the point they almost fall out of the other side of the hop up chamber, and the arms are being pushed up as far as possible, but my shots still curve up at a 75 degree angle by about 50 feet with .40g bb's. I thought about cutting the clear rubber part (hop up nub is what I've heard it called before) pushing on the bucking in half, but I just wanted to be sure I wasn't about to do something stupid.
