After messing about more and taking the gearbox apart a million times, the issue still persists. FPS is all over the board. I've checked the hop unit a million times too... Very lost.
I thought perhaps air seal issue, but I don't think an air seal issue would cause 200 - 300 fps variations?!
Gone back to trying to fix this headache. I fitted a Cyma nozzle and cylinder head, fps is all over the place still (114 - 492 on a .28g BB)
I noticed the nozzle seems to do this strange “bounce”

Replica + 7 mags & 3 - 5 day shipping for £745. Replica alone over here is nearly £700
I must admit, their prices have gone up but then so has WGC (Tiger111 was cheaper than WGC on the ak too!)
If it’s anything like their other “unique” stuff, It’ll be a mediocre design, probably proprietary somehow, cheap internals but at a high price. However people will buy it because it’s unique and tell themselves it’s good
I saw a set for sale recently, if it's still available I'll dm you 🤙
Edit: Sadly it's sold. It was on the facebook group called "Russian Airsoft International Community", could be worth checking through the impression groups etc though
