Semi auto airgun conversion project

[Sarnento]

Recently got into additive manufacturing, and thought about the possibility of something like a conversion from bolt action to semi auto could be achieved using such techniques, i do practice airgun shooting quite often but i can't afford to spend too much on it, so i only own a single PCP and two springers, but i don't own/have any experience with semi auto airguns before, and finding information about their inner workings online is fairly difficult, so im looking for advice in order to have a better understanding if this is possible/viable and some things i could change in the design

I'm basing all this on a FX Revolution airgun, which uses recycled air piston to achieve semi auto, i'm using a supressor to boost the piston since they expand and slow down gasses before escaping, and i stole a supressor design from "Plaboi" on DefCad and made some modifications on it to adapt to my airgun and accomodate a very rudimentary piston system (Still not ready to print), which would use 2 40mm PVC lock coupling O-rings to seal everything together

Still haven't designed the shaft and grooves that connect to the bolt but i'm working on it
