Time to go all out

[Villid]

Some of you know im building a VLTOR M4 right now.  With tax time coming, ive decided its time to turn my attentions to the internals on the gun as well.  Im using a G&G CM M4 as the base gun. Its currently chronoing approx. 300 fps.  When complete id like it to shoot around 380-390.  I have the spring already, but now im thinking of upgrading the internals to be able to handle play for a long time with minimal issues.  The gun has never been opened to my knowledge, so all parts are stock, and in an unknown condition.  I know next to nothing about the differnt kinds of gears, pistons, motors, etc, and would appreciate anyones input on building an all around solid weapon

get a dropin complete gearbox.

Heck no. Tax man or not, that makes no sense. A spring will cost you somewhere in the region of $15, and is all he needs.

G&Gs are solid guns out of the box. If I were you, I'd put in a M120, get it reshimmed, and run it till it breaks. An M120 is not a very stiff spring, and you could very possibly run the gun for quite some time with no issues.

Well i already have what I think is an m120.  i say think since it was given to me out of the package.  

I think im going to go with a polycarb piston, but again, i dont know the actual condition on the internals.  im owner #3 for the gun, and the original owner was hard on it.  

how will putting in the stiffer spring affect my ROF?

edit:  the m120 is NOT installed yet

[GARRETT]

Depending on your current spring, a new M120 will probably be a little slower ROF, but with increased FPS. I would consider opening it up, checking your gears, piston, piston O ring and so on. Replacing a bad O ring can do wonders, and is extremely cheap.

heavier guage wiring and a steevo mosfet

get a dropin complete gearbox.

then he hasa parcitce box to work on.

i was actually planning on giving this to dom to install the new spring already, as well as do a tune up.  so ill be able to find out what condition everythign is in then. 

id like to have a gun with a decently high ROF, it fires pretty fast now on an 8.4v.  been considering rewiring to the rear so i can put my batteries in my stock, as well as getting one of steevo's mosfets.

as well as getting one of steevo's mosfets.

I highly recommend that you do that. I have had nothing but good happen with the one's I have gotten from him.

[SteevoLS]

Yeah, I hear that Steevo makes good MOSFETs. You should definitely get at least a dozen of them.

[GARRETT]

New spring, overall Dom tuneup, and a nice 9.6 in the stock and you will be good to go.

[Dominum]

Sounds like there is a concensus then. I can tune it up, custom wire it and install a Steevofet, install your spring, and let you know if it is wise to replace anything inside or just run it as is until something fails and you can put in a better part.

[MCG]

and install a Steevofet

Not to be confused with Boba Fett.

The stock G&G internals should be able to handle the M120 without a problem, though it wouldn't hurt to replace the piston. If you have Dom tune it up, he can give a lot more info than anyone in this thread can, since no one knows what shape your internals are in.

if u can afford it, get a supercore piston!

never heard of it.  but when anythign starts with "if you can afford it", then i probablly cant
