My new baby! little problem and comments
 

Hi everybody!

My team's gun doc made an AEG from scratch for me, here are the parts used

Dboys Mk12 Mod.1 SPR frontend
G&P M4A1 Metal body
Tokyo marui full stock, modified to take 9,6V
Systema M150 complete gearbox (spring swapped for a Prometheus MS135, and modified to fire semi only)
Magpul PTS MIAD grip
G&P M160 motor
Prometheus 6.03mm inner barrel
New design King Arms Hop-up Assembly with a hard hop-up rubber

Pic to come, don't worry!

The problem I have right now is that it's shooting way too low for the setup (around 350 by my guestimates). Is it possible that the hop-up rubber is too hard? My friend has the same problem with the same hop-up rubber but in a VSR-10. And once fixed, what kind of fps will I get from it?

Also, for the comments part, what would you add to it to make it look sexier? I will add a bipod and a foldable vertical grip for sure, but those rails will still feel a little naked no?

Thank you!

If its an M150 spring shooting 350 it's likely a huge airleak somewhere, typically between the air nozzle and hopup rubber, try re installing the barrel, and with an M150 spring your way over 400fps, no hopup rubber is too hard lol

The spring was changed for a MS135

still over 400fps, the MS110 is 380-390fps
Anyway it won't be the hopup rubber unless its not installed correctly or REALLY cranked down hard.

All right thanks a lot I'll check it out!
