electric blowback gun

[peyton]

is it bad to upgrade a blowback gun to about 420 fps?

[Smartkid312]

Depends what kind.

Custom g-4 from airsoftgi.com

Yes you can, last time I upgraded a "G4" it was just a G&G CM. I got it past 4 with out any issues. (Echo Max piston, madbull 130 spring, madbull spring guide)

An m120 is more than enough to get it over 400, provided you have good air seals. A G&G shouldn't have any trouble with that.

I get 405 fps with an M120 and a .25g BB, so that's likely in the area of 420-430 with a .20g.

thanks,i was really more concerned about the blowback. i dont have any experience with ebb at all or blowbacks in general

[Lancer]

I am unfamiliar with how the blowback operates in the g&g. No matter what system they use though I'm sure it will not be an issue.

Alright then,I'm also curious if I'm going to have to upgrade everything in order to just raise it up to 430 or if I just need a few minor things like spring,spring guide,now hop up bucking maybe,full metal bushings. What I font want to do or have someone tell me is I need to go and buy systematically super torque up motor and super torque gears with an m160 spring and all kinds of stuff like that.I know I can achieve 420 fps with an m120 or an m130 spring. I don't know if the stock motor in this gun can pull that though? So a motor may be possible.. someone help me from rambling

[Hivner]

Yeah! i thought like 420 was the top fps on a gbb pistol ever.

[kenneroids]

yeah,i agree it depends on what kind.
