V2 gearbox problems

My site target is 330 but 350 max, with the ten shots I do for the chrono 1 or 2 go over 350 so want to drop it down abit.

Yeah spring is an element one, compared to my old spring it is slightly longer and does seem a few thou thicker.

When I first compared it I did think, shouldn't this be thinner or shorter.

I'll have a watch of some videos and some research into it.

Don't worry about any of it - it is working so leave it as it is

thought you might be on a 328/330 cqb site

But as they allow up to a 350 max - same as mine and it is the absolute max at mine

Anyway they allow up to 350 - you are at 345......

in say a month or two it is very very likely it will drop a bit - all springs lose their tension over time

so really don't worry about it coz you won't be hitting that in 3-6 months time

often when guns may start to drop to under 300 say then it might time to tweak / service / check seals blah blah blah

until then don't worry if you just scrape under atm, very likely won't last that high

it is hard to say but for all we know you could got a M150 or something

though I think you would of noticed the difference when fitting

(it would of fought back a bit putting in box)

could be a M130 and stock motor says f*ck this for a game of soldiers

who knows - no real way of telling without testing it

but a slim chance it could something else other than a M95

its working & leave it as is - coz 345 is ok and it will decrease a bit

The other thing to try is cycling the gun in auto so that the piston stops part way through the cycle and remains partly compressed. Leave it like that for 48-72 hours and you will find the spring will loose a little bit of its tensile strength, like cutting about half a coil off the spring. Then retest on the chrono. At your site you probably want to aim for an average of 338 with a max / min of +/- 5 FPS, which should keep you safely under the site limit. I once did this by mistake and left a spring half cocked for two months and lost about 60 FPS initially, but continued use then saw that climb back up to a loss of about 20 FPS overall.

Cheers guys, gonna try the method RR01 said and leave it at that then.

Done the half cycle method and it was still around 340 dropped about 5 fps, so I adjusted the hop ever so slightly now it's running around 335.So cheers for that lads, should be all sorted now ready for the first game of the year, hopefully Saturday.
