CYMA AKM (CM048M) basic upgrade suggestions

[mzo]

I want to do some basic upgrades to a stock CYMA AKM (CM048M).

I am not a mechanically or electronically inclined individual and have had all upgrades to my other airsoft guns done by gun docs. However I have done some research online about basic upgrades for AEGs.

So far I am considering the following:

-new spring (also to bring the FPS to under 400)
-6.01 or 6.03 mm tightbore inner barrel
-MOSFET
-Deans connectors

I would have included new hopup as well except the CM04M comes with a metal hopup and I have read that it is pretty solid.

If there are any basic upgrades that I should add please let me know.

the hop up rubber and nub, maybe the promy bridge type nub and flat rubber.
stick with 6.03 or 6.04 tb
a 6.01 in an aeg is just askin for jams just be sure to buy a quality tb with a consistant bore as thats more important.
this fet is what i just ordered, plug n play unless you want/need all the fancy features all i wanted was 3 round burst and efficentcy so thats covered in the baisic install

the gun shoots above 400 stock?

You can keep the hop up unit, but changing to a better hop-up rubber may be beneficial.
CYMA AEGs are supposed to be 400 fps stock, but I got a CM-040D that is 420-430 fps stock...

Thanks for the suggestions,

I will be upgrading the hop up rubber and nub as well and the MERF 3.2 has also caught my interest.
