G&G UMG?
 

Alright so im looking at the G&G UMG however I can't seem to get a consistent FPS rating, Ive seen 260 to 330 (how the hell? lol). Id probably still get it if it was only 260 but id upgrade it (upgrade suggestions?) to at least 320 fps. Really what im in the market for is a reliable smg, this one is at the top of my list if u have a better one im all ears.

I got a G&G gr16.
the manufacturer declares it at 280 fps, but it does 350 stock.
anyways its easy to upgrade as it comes with metal bushings, reinforced gearbox, metal spring guide...

Systema Bearing Spring guide for VIII

That'll solve all your problems.

Mine was 160-220 lol
Like Amos said, bearing spring guide made a huge difference! It was shooting 260-270 after I put the spring guide in.

well im used to the firepower of jing gong lol (atleast 340) so what can i do to make that lil sucker into a tank lol

yep, thats the one, I also replaced my piston and cylinder head, as well as the piston. Upgraded piston heads don't fit on the G&G piston.
Replacing the piston head and relubing everything makes it seal better and therefore more consistent.

lol i am no gun tech, cant i just pay someone to get the parts and do it properly?

Yes, PM'd you :)
