How to get lower FPS
 

Hello,
My airsoft mp5 fires around 440FPS stock
How do I lower the veolicity ?
Thanks for the input guys

change the spring

Sorbo pads!
Decrease the fps, and decrease the noise!

Getting a new spring is the best long term option though...

thank you gentlemen.
any suggestions as to where I should buy new springs ?
I have a G&G mp-5.

A sorbo pad will not decrease FPS.

Any airsoft parts store.

I am gona assume you picked up one of the Mp5 MAX guns? if so it should have come with a spare spring that will drop the fps to about 350ish

Actually they do... but only by like 5 FPS lol

What the hell is a sorbo pad ?

That is correct.
I just hope it was a good choice as a first purchase !

Why is a gundoc asking what a sorbo pad is?

lol. nice catch

a pad made out of Sorbothane that absorbs shock to help reduce/prevent the dreaded V2 gearbox cracking.

That chart is old but still pretty good. I talked to Illusion and he isn't going to be updating it because of too many things to do (I may do it in the future when I have some time but who knows when that will be between a job, school, and student loans).

I'd say that you should try and go with a Modify S110 to get around 380 or whatever it is (that is unless you have another spring that came with the gun).

NOTE THAT YOU SHOULD WATCH A FEW VIDEOS OF HOW TO CHANGE THE SPRING BEFORE YOU DO THIS FOR THE FIRST TIME. Or ask a gundoc to show you how it's done (Also if they're willing to do it for free it might be a good idea to bring a pizza and a 6 pack).

Also at such a high FPS the gears will likely strip (even if they are torque up gears) I highly doubt that they are good enough to withstand such high forces. So Modify S120 and S110 are exactly what you should be looking for.

The Modify 100 will set a gun to around 360-370, depending on other upgrades (ei. bearing spring guide, tightbore, longer barrel, etc.)
