Retro Valve not rapid firing?

[kfletch]

Hello,

I recently upgraded my old Minimag to a Retro Valve, and was hoping to get a little more action from it than I'm getting. It definitely fires faster but I was hopping to get it to rapid fire. I bought a Ninja SHP regulator that is putting out 1100-1200psi and adjusted the sear so thats it sits just behind the trigger. The On/Off is the standard RT not the ULT, is that what's needed? What else do I need to do? Here's my Mag...

Thanks in advance,

Kevin

Pull your trigger slowly until you find the sweet spot where the mag will go nuts RTing.

Done....

I've done that and it just wont bounce. I have also noticed it half stroking from times, and I thought the upgraded pressure would make that impossible.

Apply pressure at the top of the triigger not at the bottom.

I've felt up the trigger more than a drunken prom date, and she ain't firing. Would an old O ring in the on/off cause it not to rapid fire.

Have you checked your velocity? A lower front chamber pressure (lower velocity) will help with reactivity. Are you using a level 10 bolt. If you are, then a shorter, lighter bolt spring will help make it more reactive. Also, try putting a shim or two in between the on-off halves. It will push the top oring up a bit higher which will reduce the distance the sear needs to travel to close off the air supply and release the bolt.

Haven't checked the velocity yet I don't have a chronograph. No level 10 yet, but planning on it soon. I just have a foamy level 7. I'll get to the hardware store soon and try the shims out. Any other suggestions are welcome.

When my x-valve has trouble rapid firing i will go into the power tube and put oil on the oring in there. Then drop oil in the elbow like normal and that salves prob every time. Make sure its a good quality oil.

The shims AThomas is talking about are only for ULT on/offs which you said you do not have. If you are still getting bolt stick, this will effect your RT. You need to change the Level 7 spacers. You also need to get to a chrono to determine your FPS. You can get the spacers either from the AGD online store or from Tunamart. This needs to be fixed before you can really proceed.

I was referring to adding shims to the standard retro on-off. You can put ULT shims in between the two on-off halves. It will push the top part farther into the valve which is the same as using a shorter pin. You can only use a couple of shims here or it will squeeze the top oring and make it too tight.

I apologize and stand corrected. I had never heard of doing this before.

one of the first steps in installing a new xvalve is cranking the velocity. I set my in put pressure around 900 psi.

me too

I also have the same issue whit the same setting RT retro valve on a minimag same color too!! (like color would change something... loll )

unable to sweet spot making the trigger bounce, when I tried to do it it shoot half power 2 paint balls I'm guessing half stroke , double feed then fires 2 simultaneously

///so the bolt doesn't go all the way? not enough air and/or spring too strong ?///

If something works please post it so I can have an idea of what to do to make it bizzzzzzzzzzzzzzzzzzzzzzzzzzzzz ! I saw one on youtube ripin saying he just sanded on/off pin... I don't know before doing something irreversible ....

Basicly what you need to do. Don't shave it down more then .710 or you can buy yourself a HP reg that pushes 1k +. If you have a lvl 10, install the gold spring. It'll be harder on paint but RT a lot better.

yeah already have 1100 psi pressure from a flatline that might need something (see my tread in tech forum ) and no lvl10 yet so I'l sand this down a bit and see what happens

thanks
