Automag RT pro x-valve problem

[Roel]

I'am looking for some more bounce on my trigger. So i need a adjustible reg. for some more psi.
But i just gast up my gun to find that it was going ballistic, with the lightest trigger pull. Just fullauto i want that.
My problem now is that the gun jammed (lvl10)on a ball. So i de-gast the gun, and cleart the feedport. I again gast up my gun but it just fired normal. :cry:
Can somewhan tell me what made my gun to this?! Thanks
sorry for the lame english(i'am dutch) :ninja:

A piece of dirt in the on-off atea was most likely the cause of your full auto problem. If you want more bounce in the trigger, you need an adjustable tank to increase the pressure feeding the valve.

You can also get more bounce by using a shorter on-off pin. The rapid fire sweet spotting that you are talking about can lead to rapid wear on your sear and bolt.

Oke, I really like the fullauto. I have spare parts for it so wear is not a big issue. I will try to get my hands on a adj. regulator. And hope i get some more. :bounce:
What i dont understand is that the sear is holding the bolt down. But how can it go fullout, does the bolt slip over the sear or something?

The sear is forced to bounce up and down with the returning air when you manage to get the trigger position in just the right spot, it's big and clever! Also as long as your bottle reg puts out around 800-900psi + it'll bounce like a space hopper! You don't really need an adjustable one. If you want upgrade to a higher pressure reg centreflag are a very high flow fixed pressure reg. Mine puts out 850psi and bounces like a baby! Mine is also quite an old reg, i hear the new ones are even better. They're also very cheap and durable (around $45-$50 in ht U.S. or about £30 int the UK)M, and one of the smallest to boot.

Thanks, only thing is the dynaflow or maxflo reg's are almost not available in europ :( So i'am scrolling in the selling thread for a reg and somewhon who is willing to ship it over here.
I really like the mag it shoot's great, and i'am saving for an x-mag there reall beauty's!!! :wow:

When you have a high input pressure and you hold the trigger is the "sweetspot", you get full auto. This occurs because of the differential between the pull force and the return force combined with the placement of the sear and on-off pin. The retro effect comes by pulling the trigger at 4 lbs of force and having it kick back at 8 lbs of force. By sweetspotting the trigger you have a relaxed trigger pull that is just enough force to pull the trigger assembly and fire the gun. The incoming recharge air has more force than the trigger pull and pushes the trigger assembly forward. Once the recharge has happened the higher pressure doesn't exist anymore and the trigger pull force pushes the trigger assembly back into the frame to fire the gun again. Each complete cycle creates a rocking motion on the trigger assembly which results in a fire and recharge. As long as you hold this position, the cycle will continue.

By increasing the input pressure, you increase the differential pull force which allows you to pull the trigger without holding it in the pulled position during recharge. This makes the sweetspot larger.

Wear occurs because the sear never fully resets. It catches the lip of the bolt and then slips off to fire the gun again. A properly setup mag, with a proper on-off pin and working in complete cycles will have less wear on these parts. A high input pressure is a better way to provide the full auto sweetspot than by shortening the on-off pin. At least the high input pressure still requires a full trigger cycle to fire the gun. A short on-off pin doesn't require the sear to completely engage the bolt and can result in the sear tip slipping on the edge of the bolt, which will definately accelerate the wear on both parts.
