unwanted reactive firing, please help!

[don miguel]

I have lost days of paintballl play with my retromag because it is reactivly firing (illegally). When I pull the trigger it fires, when I realease the trigger it fires. Both are occuring in complete cycles. I have replaced all the orings in the on/off, vlave, and everything. I have no idea what is going on. here is a picture of my valve if this helps:


Is it just the valve? I meed help.

what kind of tank are you using??

[don miguel]

what kind of tank are you using??

Exactly this:

Pure energy 48cu 3000psi.

is your sear worn or is the on/off pin worn ?

[cyrus-the-virus]

Get a classic sear if you like a heavyer pull

or a ULT kit if you like a lighter pull, both should stop rective shooting.

[MANN]

that valve can probally not accept a ult.

do you have a micrometer?? if so how long is your on/off pin?

[BigEvil]

A longer on/off pin will kill the reactivity. It would help to know what size the one you have in there is though....

I am having similar issues excpet the marker will "full-auto" if I sweet spot it. I have already changed out the entire on/off assy including the pin. Changing the sear and/or bolt was going to be my next step. The sear that is in the marker looks worn/filed on the nub that would contact the on/off pin.

Could this be the same thing the OP is complaining of? Think changing the sear out will fix it?

Thanks in advance for your help.

I started a thread a while back with a similar problem. It sounds like it could be different for different people/situations, but all I needed to do was get a longer on/off pin (previous owner had sanded it down) That would probably be the best place to start considering the price of a new pin compared to a ULT kit or new sear.

also check your trigger rod length...if it is too long, it can sometimes cause it to bounce.

/don't read into that sentence too much behemoth

I've found (with x valves) the marker will go full auto if the regulator seat oring is in the regulator seat holder. If you take it out of the holder and place it in the back half of the valve instead, this usually fixed the full auto problems that I had.

That is a micromag valve. If you are using a shorter micomag on-off pin in a regular mag body and rail, then it is probably causing your full auto problems.

Based on what you are describing, it sounds like an on-off pin problem.

[DaFin]

I should have clarified the ful auto is in AIR valve (AKA: Classic), the body is an old school PF left metal body. The on/off valve is a Classic O/O just purchased from AGD.

Sorry for the hi jack.

where do I get a longer pin? I do notice that when my gun gasses up, the sear hits the trigger and I can still pull the trigger out a little, do you know what I mean? thanks for all the help by the way.

I have all of those things you described, can you buy longer on off pins at airgun.com? sorry for the multiple posts.
I have this stock pin:

What other pin do I need?
