Uber MP5K
 

Hi,

I m considering modifying a TM MP5K, basically, increasing it to around 350 fps while keeping a maximum TM parts in it.

Stock TM MP5K with:

- Prometheus 110 mm 6.03 TB
- Prometheus v3 spring guide
- Prometheus metal shim
- Prometheus Non-Liner Spring MS110 350-360 fps (should be lower with a short barrel)
- Running on HOT POWER 7.4V 1600mAh 12C Lithium Battery (AK Stick)
- King Arms 6mm Oiless Metal Bushing for AEG Gearbox

Would this config make sense?

Thanks

Will this gun be using indoor or outdoor ? Keep in mind that indoor is limit to 350 fps but it's not the goal.

You configuration look fine, possibly upgrade the hop up rubber to Guarder clear and maybe Modify airseal nozzle for MP5K to be consider with correct port cylinder then do the compression test to see if there is any air leak.

Edit : If it's zero air leak, you may consider Modify M100 spring or M90.

remember you won't easily find spare hop-ups for mp5k...

I would probably use a 100 spring, but for outdoor a 110 should work fine too.
