You can stick a set of Siegetek 10:1s in there, you'd get 60 RPS and a stripped piston in 5 seconds if you have no idea what you're doing. In most cases, parts that are "good enough" in terms of quality are as good as the person installing them. If you have a set of Siegeteks, you can still break them through improper installation. I've seen it happen. Same with your piston, and it sounds like you've made a very poor piston choice for a high speed setup.

Here is a sample of a high speed build I did for a client, prices removed.

Base gun: VFC 416

BTC Spectre
Siegetek 10:1 Gear set and pinion
Tienly U30000 Long Motor
SHS 14T Ported Piston
Lonex M4 Cylinder Head
Sorbo and Neo pad combo
ZCI steel full cylinder
Lonex POM Piston Head
SHS M4 Nozzle
SHS V2 Tappet Plate
Ace1Arms M120 Spring
Modify Shim Set
Reinforced Steel Tappet Spring
Piston Head X-Ring

PDI 6.05 285mm barrel
Lonex M4 Hop Up Unit
R Hop Installation on PDI

-R-hop installation on PDI barrel
-Lonex hop up unit assembled, modified, nub installed
-hop up shims added
-hop up rubber modified
-mock bolt modified to prevent hop up interference

-pinion installed
-sector gear short stroked
-piston rack glued in
-sorbo installed, AoE adjusted
-piston head thread locked into piston
-all air seal surfaces lubricated with silicone lubricant
-gears lubricated with PTFE grease
-BTC Spectre installed, selector shimmed, trigger pull shortened
-gears shimmed bevel-pinion
-tappet plate modified for better air seal
-anti-reversal latch modified for Siegetek gear set
-nozzle cut to length

Pesto in all honesty your builds are incredible I'm very much aspiring to get to the level of excellence and craftsmanship you have. So I'm glad we've established my user error I'm not ashamed to admit that I literally started Teching last year. So maybe you guys could give me some pointers or methods you use to shim/correct angle of engagement like. Do you shim bevel to pinion what gear should i shim first should I use bearings or bushings? How many teeth can you safely remove on a piston to correct AOE etc...
