Spring

[DJ_Fiesto]

Hello,

I bought a Vega Force Company M4ES Quake brand new and I was told when I was buying it that I should switch the stock spring with the new spring that came with it. I installed this new spring and my gun became a lot louder. Is that supposed to happen? If someone could please answer my question that would be greatly appreciated

Thanks.

Stronger spring = higher piston smack value on the cylinder head.

Easy enough, eh?

I'm pretty sure he downgraded the spring Stalker. It would seem like a weaker spring is making more noise. At least thats how I read it.

Hmmm, he actually says neither...........

What exactly is louder? Is it the piston hitting the cylinder head or is it the gear sounds?

Is the motor height set right? Did you maybe lose some shims off the gears when you took apart the rifle? Did something else crazy happen? Was the spring that you installed "harder" than the one that came inside it out of the box?

To be honest I'm not an airsoft guy I'm more paintball do I don't know a lot about the interior of an airsoft rifle. I took it to where I bought it (Heroes Army Surplus in Oshawa) and got their airsoft tech to put the gearbox back together. The new spring that came with it was longer than the stock spring and what he told me was that this will decreases the velocity of the rifle and won't hurt the gearbox thus preventing my gun from being "destroyed". I hope this info was helpful

It's probably all in your head. If you do a search on vfc quake they are supposed to be loud. And whatever spring they put in was your "stock" spring because the gun had to be upgraded for exportation purposes. Hope that helps

What was the airsoft tech's name/callsign?

Spring lengths will vary between manufacturers (i.e. a Guarder m100 spring may be longer or shorter than a Modify m100 spring)...and they'll differ in length from power level to power level.

Longer and shorter won't "hurt" anything unless:
- the spring is so short (and some dummy would have to cut off a lot of it to be too short) that when fully extended it doesn't push the piston all the way forward. Again...with any non-altered part this shouldn't be an issue...but you see some weird things on altered guns

- the spring is so long that when fully compressed they do not allow your piston to retract enough when the gears cycle. This is possible depending on your setup...bearing spring guides and bearing piston heads will take up space.

In general...a spring will only decrease FPS if its power rating is less than the one you currently have in there.

A really stiff spring puts a lot of load on all the bits&pieces in a mechbox...and will speed up the wear and tear. ANY mechbox can suddenly/catastrophically break. EVERY mechbox will wear out...a good setup with good parts just hedges your bets and delays things.

When you change the spring to something lower do you have to re-shim the gears?

[m102404]

shimming is ALWAY worth checking...but technically, no...if it's done right already you don't have to reshim your gears when you change a spring.

...I'd always check anyways when the mechbox is open
