on\off question

[tone]

ok when i gas my gun up now and then ungas the gun it holds pressure in the on\off and even if i pull the trigger it does not get rid of the pressure ... when i take the valve the on\off shoots out .. and i dont like the idea of the pressure being there all the time if any one could tell me why this is or how to correct it it would help me alot

You can't correct it so just get used to being careful when you take your gun apart shortly after playing with it. The gas is trapped between the regulator and the bolt, b/c the bolt acts like the cork in the proverbial bottle. It kind of freaks you out the first time it happens but after that you learn to pull the back of the gun out fairly slowly until you hear the on/off 'pop,' at which time the pressure is vented and you can go ahead and pull the guts the rest of the way out of the gun. FYI, it's not a lot of pressure and it usually dissapates after the gun is degassed for a couple of hours.

I find this a bit odd, on both my classic AIR and ReTro valves, when I pull the macro line or quick disconnect from the gas inlet of the valve, this completely degasses the valve. The only reason it should be able to retain gas between the on/off and bolt is if the on/off is closed and the sear is still holding the bolt, which would basically mean the gun is incapable of firing anyway.....

Are you sure you don't have any backcheck elbows or valves on your marker?

Ok, first of all, there is a great discussion of this going on right now in the main forum, with a lot more info. Tom said he is looking into it right now.

Actually, no, we shouldn't get used to it, because our vavles are not supposed to do this. I know because my valve does this too.

Ok, does your valve have level 10 installed?
Is the tank unscrewed and the air out of the lines (I assume it is) so the pressure is soley in the valve?

If you have a quick disconnect, did you look at the fill nipple part, to make sure it doesn't have a one way valve inside it? That will keep the air in the valve. The one way valve was for installation on the fill nipple of a tank, and putting that fitting on a quick disconnect setup will keep the air in the valve.

If it doesn't, they we will both have to sit tight. There are others experiencing this same kind of problem.

gun

gun shoots great with air and i un screw the tank and it still holds air .. it just started doing it and yes it has LX on it

A side effect of the LX bolt's "easy on paint" feature is the fact that a Mag equipped with this bolt now holds a much higher residual pressure inside its dump chamber once the it has been degassed. This can result in the on/off pin actually being launched from the marker if the valve is removed before the residual pressure leaks out. AGD is working on a solution to this problem.

Some sort of bleed mechanism for the dump chamber would be my solution, but getting that to work with the current marker architecture (and still look nice) could prove problematic.
