View Full Version : Quick Pnuemag question

I find I have to turn my tickler all the way up to get my pnuemag to fire. Should I put an RT on/off in the Classic valve to get it to fire with less pressure?

it would help. Try a quad o ring set up as well.

Post a pic of your set up (inside the grip frame). If there are other things that can be changed we will let you know.

All the up as in can't turn any further? If so then you probably have a kink in your micro line. Using a ULT, or RT on/off, having your actuation rod hit the top of the MSV-2 arm and having your MPA-3 hit the very lowest part of the sear leg will also allow you to use the lowest lpr setting and give you the lightest possible trigger.....

Cranked all the way. I'm pretty sure my microline isn't getting in the way, but it is tight in there. Lots 'o Pics!

The piston is hitting the sear arm as low as I think is possible.

Your MSV-2 lever is really short, which increases the amount of pressure needed to trip the valve. I don't know for certain if that is the problem, but longer is better in tripping that valve.

Looks like the hose coming from the LPR and the one going to the MPA-3 gets crimped when the grips are installed. Try it without the grips on. Double check the hose routing to see if it's tight anywhere else. Also your MSV-2 arm has been cut down, but I don't think that is the reason your having to turn your LPR all the way up. What kind of LPR are you using? Have you tried to clean it out or see if the inlet tube is blocked in any way?

I'm using a Tickler LPR. The microline doesn't appear to be getting in the way, even with the grips on. I'm pushing on the line the same way the grips would and the sear is moving freely within it's normal range.

Can someone please explain "quad oring" setup?

A quad o-ring AKA X-ring has less holding force than a standard o-ring.

Take apart your Tickler and see if the barb is protruding all the way through the LPR and into the body. It may be preventing the piston from moving and allowing it to fully pressurize.

you may want to take take the top off your tickler, remove the spring, and stretch it out.

This will give you a little extra boost.

Sometimes they get compressed which reduces the output.

Ok, so this just replaces the two orings above the on/off right?

I had the same problem. With the classic on/off, I had to turn the LPR all the way up to fire, and even then it wouldn't always fire. However, with an RT on/off and quad o-ring, I only have to turn the LPR about 1/2 way.

Ok, I already have a .750 length pin, so Do I just need to order these?:

Are there any other orings I need other than the quad ring thingie?

nope, that should do it.

Contact mann (Josh) I think he may be able to beat that price. Also using a quad may not work with the .750 pin. You may need to shorten it or get a emag pin (.712). The .750 pin will work with the standard 2 o-rings....

The classic on/off pin does not work in the RT on/off. It is also .750, so I'm thinking that you mean you already have the classic pin. The RT on/off will cut the needed pressure in half. The quad oring works well, but the .723 pin on a standard oring is good too. I think there is an entire RT on/off setup in the AGD store as well in the BSTs. Either way you need an RT on/off pin.

The quad just replaces the little oring at the top. The larger one is still used with it in the classic valve. Don't bother trying a quad with a .750 pin. It doesn't leave much room for air flow and there is at least room for improvement with a shorter pin, if the performance is decent in the first place.

I have an MSV-2 lever that is a little shorter than that one. The arm length only affects how much of the lpr pressure you will feel in your trigger finger. A shorter arm doesn't need a magnet mod either. It's just not as pretty an installation.

The pin I have is out of a RT valve, I just replaced it with a shorter pin in that mag to get a little more reactivity. Thanks for the help guys.

Did you figure out why the LPR had to be turned all the way up.

Sorry to hijack the thread, but I've been using a quad o-ring with the .750 RT on/off pin. Could that be causing shoot-down when I try to shoot fast (10bps)?

Definitely. While fighting a worn sear I went from a .712 to a .750 and could only get about 1bps. I went back to the .723 and my rate was back up. I eventually had to take that sear out anyway; it wasn't in good shape when I got it. It's nice to have a few pins of different lengths to experiment with. :)

You can try adding a couple of level 10 shims to your RT on/off body. They don't ride as well as in a ULT, but it will show you the difference without requiring any permanent changes.
