Low Pressure Gun Problem
ok...so i went low pressure. I have a trinity front block, a cp reg, barrel, ndz valve, and a acs bolt.
the problem is when i shoot, i can shoot the gun the first few shots are ok and then later the gun sputters and i can't recock as if it is out of air. how do i fix this. i'm running the gun at a weak valve spring and a strong main spring. When i turn up the psi, i shoot too hot and still sometimes i have recocking issues. How do i fix this?

Re: Low Pressure Gun Problem
Unfortunately every gun is different and really you'll just have to play with it until you find the right combo of springs and pressure. Make sure everything is clean and well lubed. Make sure there is no damage to your striker or sear. You could also try a lighter striker, but I'm not sure if that would help that much.

Re: Low Pressure Gun Problem
what happens when i change the valve spring?
like from light to heavy...does it take less air or something?

Re: Low Pressure Gun Problem
Try a medium or lighter valve spring. You really need to try many different spring combinations and use the one that works with your marker best. Most find out that using a random combo that worked in someone elses marker is a total disaster in theirs. LP really isn't for the lazy -

Re: Low Pressure Gun Problem
A light main spring will require less air pressure to push the striker back into the cocked position, however it goes forward and hits the valve pin with less force that a heavier spring. Finding the balance between your valve and main spring can be tricky but if you dial it in correct it could be very rewarding. Also remember that lower isn't always better. Just because you can get your marker down to 200-250 psi, doesn't mean that its good for your marker. You need to find a pressure where you get the best efficiency and your marker operates flawlessly.

i just didn't have time to change valve springs. so many people were rushing me to the chrono.

Re: Low Pressure Gun Problem
I've found that relatively 300psi holds a great balance in LP Spyder's -
Far as rushing you goes, go on a day that you're not playing then there's really no rush -
