But it doesnt change the cycling problem... My piston dont stay forward after each shot, it stay at the middle of the brass tube. Do you think its the cause of the low FPS??

This is normal for ANY gun using ANY spring provided that the battery you are using is more than enough to pull the spring.

Only way to fix this problem is to get MOSFET with Active Braking, or you can install a stronger spring that the battery can barely pull.

I say go for the first option

Okok so if it's normal, I need to find another problem that explain the low fps...
Maybe the cylinder head is really the problem

Your cylinder head could be letting air by, or it could be your piston head.

I receive my sorbo pad, thanks for the awesome ARS's customer service and also thanks to Amos!

I also buy a Modify cylinder head and some grease form airsoftparts, should receive it next week I hope.

ledor473 · November 25th, 2009, 23:03

Great news, I receive my command today!

Bad news: I install everything I got, I go buy some white lithium grease, I grease it and it's still not working great....

Problems:
-Misfeed (way too much!): possibly the 9.6v Elite that I use?
-Low FPS (do not pierce a Pop Can)
-My hop-up seems to move a little bit more... maybe it can cause the misfeed but can't know how fix it...

Piece in the gearbox:
-Modify Cylinder Head
-Modify Anti-reversal latch
-Metal nozzel
-Orange piston head
-Normal brass Cylinder with a hole on the side
-Unknown brand irregular spring
-Everything else seems stock

Any idea? Any gundoc near Quebec City?

If you feel like shipping you could send it to me, I know V3 mechboxes very well.

However -- if it needs new parts it wont be cheap; Modify is the lowest quality brand that I use (and some people rank them #3 in the lists of top manufacturers lol)

ledor473 · November 25th, 2009, 23:31

Well, I have to admit that I would like to send it to you, I mean you seems trust-able but I don't have 1000$ to put in this UMG... If Modify is the cheapeast parts you use, I don't have necessary fund to handle it...

Well I probably have, but do I really want to put this in... the problem is: how much can it cost me? And the second one is that you need to see it to answer the first one

EDIT: If I dont solve the problem since the end of the winter you may receive a PM...

It wouldn't be $1000 lol the most expensive internal upgrades I can do with modify parts is around $300 and with labor if things take me 5 hours... which I highly doubt it would (normally takes me around 2-3 if I'm being thorough on a V3) total cost would be about $400 max.. and that's if I've got to upgrade everything inside it lol

ledor473 · November 26th, 2009, 00:03

Well I know that for you it's not very expensive but for me it is... I know you mean that it's gonna cost me less than that but....

Anyway I will think of that.... if another gundoc live closer, I will prefer him (only for the shipping cost, face-to-face deal, etc

)

Haha I'm a 20 year old college student! It's not like I'm some business CEO that drives around in Porche!

ThunderCactus · November 26th, 2009, 18:00

Could be the spring
I had a G&G UMG and it shot 160-220fps out of the box (but deadly accurate), and all the components sealed just fine.
I put a stock CA spring (that was shooting 305 in a CA M4) and it shot 280fps consistently

Lmao!! Amos when I get my gun, when I get AVed tomorrow, you might be getting a PM to upgrade my guns internals... I won't have a clue what goes where.

ledor473 · November 26th, 2009, 20:31

@ThunderCactus: It's because when I receive it, it was shooting stronger, at least was going throw a pop can...

I'll try to find another spring and test again...
