Experience with green valve spring?

[iamthelazerviking]

Has anyone used one of these? What is the advantage?

Well, from what Ive learned from MCB. It would allow a longer dwell in your shot. Likely allowing a lighter hammer spring, or raising velocity. This could reduce efficiency on co2, or make your shooter more usable on hpa? I dont know much about phantoms specifically. But thats my guess.

It would likely result in lighter pump stroke and q floofier shot.

I thought I had read somewhere that the red main spring (stronger) would keep the valve open longer allowing for higher velocity but less efficiency. With that being said wouldn't matching the springs (using the blue and green) mean lower velocities but more shots per 12 gram?

Following need to learn more.

There is no “Advantage” by slowing down the valve with a 25% lighter spring.

Don’t mess with perfection. The stock Silver springs sweet spot at 825psi HPA, and will shoot over 40 shots to a 12g above 65* @280fps. It will run both pew sources without changing springs with very little TPC adjustment over the chrono it’s quite and consistent. Performance is as good as your going to get with a non-regulated setup.

Any “tuning” you do to a phantom outside of its stock internals and spring combo will be a trade off in its perfect balance in performance and efficiency.

I agree. The best use for swapping springs in a Phantom is to return a used one to stock after the previous owner messed it up.

Go ahead and play with springs if you’re actually improving your gun but…improving a Phantom in this way is not likely at all. Clever theories about hammer weight or valve bounce or hot rod valves or whatever don’t hold a lot of water in the real world where a %100 stock Phantom does everything perfectly except for rollouts. When it comes to internals, “worse” is the only direction you can go in, really.

[Chuck E Ducky]

Agreed Leave it alone get a detent mod. It’s the only thing that actually effects performance and make the phantom so easy to use. It’s the only performance mod really worth anything on a phantom.

[JeeperCreeper]

Only thing you need for efficiency is a tight bore barrel, like a Phreak or anything around .680.

[Jonnydread]

Agreed. I have a .681 Lapco on my Phantom and I'm getting 4 tubes around 270 no problem

[AnarchicArctic]

I 100% agree with silver springs set it and forget it. But…I’d definitely be interested in a real world, over the chrono, shot counting comparison of silver springs/stock guts VS. green valve/blue main/trifluted hammer. You know, for science

each vale spring will be different for each person. do to face where i live in FL will not be same spring in so cal. and same if leave mountains or high elevation too. going to have find one best fits for area you live in.
