Need help please.

I'm having problems getting my velocity down below 300ft/s with my e-mag. I've had to crank the incoming pressure down to 500 psi in order to stay around 280ish ft/s. Now the gun itself says to keep the pressure from 600 to 800 psi. is running it at 500 going to hurt it? Also, why can't I get the velocity down while using 600 psi? Any ideas?

My setup is listed below.

What spring are you using in your setup? Remember, the longer the spring, the lower the velocity you will end up getting. Also, what carrier setup are you using?

Also, you want to have around 600 going into the gun. I think after we solve this, you'll be able to adjust your incoming tank pressure up again.

Thanks Dayspring!

I'm using the Lvl 10 Carrier size 1.5, with 2 Shims. I'm also using the gold Bolt Spring.

[Dayspring]

Ok. Try moving up to the medium spring (the one with the snipped end). Put the snipped end on the bolt. This should allow you to up your pressure and get the velocity under 300.

If that STILL doesn't work, take the long spring and use that. If it starts venting out the back (perfectly normal. it's a pressure release b/c the velocity is too high) turn down the velocity. You can also start snipping off the long spring until you get it to the point of firing under 300.

Check back in and let me know how you end up.

What happens when you turn the velocity down using the smallest gold spring? Can you reduce the velocity and have the gun still fire? Have you taken the valve apart and checked the regulator seat o-ring? If this o-ring is leaking, it will keep the front chamber fully pressurized, effectively bypassing the regulator.

Dayspring - I'm currently at work so I'll try that when I get home, thanks a lot!

athomas - using the gold spring I reduce the velocity to the point that my paintballs just role out. But, once turn it ever so slightly, it jumps all the way up to 301+ ft/s. So that tells me that basiclly I reduce the velocity to the point that it was leaking the air out. I've taken the Valve completely appart (minus taking the regulator nut and internal parts out) and oiled every o-ring I saw. Doesn't look like anything is leaking.

[athomas]

Are you sure you checked this o-ring?

I would also check your reg springs and the reg piston. if it is going from nearly no output to full output with very little adjustment, it almost souunds like the reg piston is not reacting to pressure changes correctly.

[Noxlupus]

Just to keep you guys in the loop and because you were kind enough to help me out here. I haven't had a chance to do the modifications yet. But, I'll be sure to let you all know the out come!

Again, thank you for all your help!

Well no luck what so ever!

While I was at out at Extreme Paintball in Six Mile, SC this past weekend I had a few people take a look at my gun. Well we changed out the spring from the standard looking one (golden) to the longest spring with no luck. The velocity was still above 300! Controlling the velocity on the gun itself proved to be a hopeless venture.

Conclusion thus far is that the regulator on the gun is shot. *sigh*

[xen_100]

there is no such thing as "shot" if you replace the reg seat, regpiston o-ring, and the cup seal(if it is worn or look bad) it will work fine again.

unless there are gouges in the body of the regulator itself, there is no reason it cant be fixed.

[athomas]

Take the entire valve apart and clean it, including the regulator assembly.

i had a leak/spike issue on a retro valve. take out the spring pack in the middle of the gun that rests under the brass o-ring seat/collar (not sure of the technical name for it). see if it's dirty. wouldn't hurt to clean it anyway.
when replacing the brass o-ring seat/collar, do not push it into place before screwing the reg back on. just place it back on. screwing the reg back on like normal will seat it enough. too much pressure activates the spring just enough to cause barrel leaks.
see if that helps.

[Noxlupus]

Well found out what the problem was... Thanks to athomas' picture I was able to finally see what it was. I was missing the golden/copper disc that comes after the regulator seat o-ring.

I put that back in (I'm not sure why or when it was taken out?) and it work perfectly.

Thanks for all your help everyone!!
