Hello ACS Community!,

I have a question for you guys! I have been getting better and better with AEG upgrades and mods, and I am always wanting to know more about them to enhance the performance of aeg's. I have my setup that i've built and I finished putting it together and she runs amazing except for one problem (currently, TONS of trouble shooting has taken place up to this point to make the gearbox run). I have near-perfectly shimmed the gearbox, short stroked 3 teeth, corrected AOE (both shaving teeth from piston & adding 70D sorbo pad), swiss cheesed the piston and so on.

Currently, the issue that I am having is that the nozzle stops in different places which is leading to the rifle not feeding at all. I am hypothesizing that this is either from pre-engagement (although unlikely as the short stroke and AOE corrections should eliminate it) or over-spin. Would you guys have experience with this? How would I adjust/fix this issue so that this does not happen any more?

Bellow is my complete gearbox setup for my VFC 416 CQB:

Lonex Gearbox (bearings, not bushings)
SHS M4 nozzle
Lonex aluminum double o-ring cylinder head (equipped with 70D sorbo pad)
Modify enhanced cylinder type-1
Siegetek Revolution 14.09:1 Gearset (short stroked 3 teeth off pick up side)
Lonex Titan A1 Motor
SHS 15 tooth piston - full metal rack (filed 2 teeth after pickup tooth for AOE correction, short stroked 3 teeth off release side and fully swiss cheesed)
Lonex POM Ventilated Piston head (Ball bearings installed)
Stock VFC bearings spring guide
Lonex cutoff lever
Lonex tappet & selector plates
Lonex M130SP non-linear spring
PiccoSSR 2 Mosfet (installed using setup #2 on installation guide with 16 gauge silver wiring)

I think thats about it for the gearbox, so please let me know if you need any other specs. My goal is ~395 fps. If you could please let me know your opinion on this matter, it would be greatly appreciated. Thanks for your time.
