PDI hop up for L96. Won't turn "off"

[Nixtwiz]

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.

To turn the hop off, you screw the screws in. They push UP on the arms, lessening the pressure placed on the nub. I am not seeing how they could go out the other side, which is where the arms are. BTW, I have the EXACT same PDI unit and am looking at it now. I am laughing at you because you had it backwards. Just look at how the thing works guy :lol:

No you don't understand, I have screwed them in as far as they go, but the hop up is still 'on.' And they can fall out the other side, because the length of them is shorter than the distance the arms can move up. And the arms can't possibly give any less pressure at this point (they are squished up against the outer barrel). yet it still curves insanely high.

Replace the bucking. If there is no pressure on the nub, its a bucking issue. Make sure it is installed correctly. The PDI unit has a very tight fit. Bucking could also be too long, because then it would get pushed on by the silver barrel retaining spacer and possibly warp. The factory nub is awesome though, so don't touch it. If all else fails, try heavier BBs.

try heavier BBs.

I use .40g and sometimes use .43g. Any heavier and they'd be metal

i have the same unit and have had some issues with it as well. sometimes it is the placement of the bucking for example sometimes its just not fitted right and you just have to be patient and try it multiple times. after you think you have it in right make sure all the lube is out of the barrel and the bucking.

one thing that made a huge difference in my shots was getting a Shredder's Concave Hop-up Spacer.

If you have anyother questions just pm me, if you live close enough i could take a look at it with you and help you out maybe.
