If you can’t fix it with a hammer, you’ve got an electrical problem 
Hey FF that o ring you suggested, do you mean placing it at 1 (before the nozzle tip is glued on) or at 2?
- Between the tip and the nozzle itself.
Though most testing in cyma boxes with that nozzle has usually been borderline too long if using the cyma tpiece.
My testing with it with cyma tpiece has been a gel that might have jammed won’t feed, but seal has been fine.
Thanks mate, I’ll try the original nozzle and tip first followed by the o ring trick second to see what happens.
I’m also now wondering if I glued the barrel in on this one when I replaced it. Will check tonight
Apply moar power. Works for me 
The barrel wasn’t glued in so that got done and retested but unfortunately that wasn’t the magic bullet, FPS was the same glued or not. The friction fit on that was decent.
With that question answered moved onto testing with just the original nozzle, dropped from 300 down to about 285FPS.
Tested with an oring spacer, the LDT nozzle was longer than the OG nozzle so ended up giving me feeding problems (as predicted) 1 in 5 wouldn’t feed or would break up. The ones that did feed well got about 290FPS. A great test anyway that I’ll remember in future, thanks FF
Took a few measurements while I was at it
Landed back at this setup again
80% Cylinder
LDT cylinder head
Polymer piston head
Pink piston
16:1 with two teeth off
275mm 7.5 barrel
T238 29k motor
M110
With the cylinder, cylinder head, piston and nozzle out of the box the airseal testing is excellent, I cant force the cylinder in by hand. Maybe this is as good as it gets
