Gun only works without frame?!

[boardfu]

I got a used micromag off ebay. classic valve. stock. i fixed it so that the gun wont leak when i have the trigger frame off of it, but when its on, it hisses out the barrel. I believe its a Kapp 45 frame. I see no rational explaination of why this happens. any ideas?

How are you holding the gun together to gas it up when you have the frame off?

Check when the frame is on that the trigger rod isn't pushing up against the sear when you gas it up.

micromags have an integrated body/rail. you can completely remove that frame and still have it shoot.

I found out that if you dont have a pressure on the trigger when its on its "ready" phase, then it will leak. Ever notice that when you gas your gun up, the trigger rod is right up against the trigger? If rod were too short, or if the trigger were too far away ( which happens if you have an aftermarket frame like mine), then it leaks out the barrel.

I have determined that my problem is that I have to find the proper trigger rod length that will 1: be long enough to Keep pressed against the trigger 2: be short enough that the trigger will not force down the on/off assembly causing the "sprinkler" effect. and 3: Will activate the on/off properly.

I learned all this from taking apart and putting back together my mag over 200 times. quite annoying. hopefully i find somthing that works.

If the trigger rog is touching the trigger when gassed up it is the wrong length. You NEED a small gap between the two. The sprinkler effect is caused by bad/worn on/off orings. Change them and shorten the rod a turn or so and try that. Report back here with the results.

I know how micromags are setup. What I wanted to know was how you were holding it together to shoot it with the frame off. Doing that is potentially hazardous.

Tunaman covered everything else, let us know what you find.

I would put the feild strip screw in, and press on the trigger.

frustrated. Tried every trigger length. brand spankin new o-rings. New on/off.

If slightly touching the trigger stops the leaking out the powertube, then you need a shorter powertube spacer.

You need to hold the valve taught in the back of the body. You can only do this if the valve is properly secured when the grip frame is on.

The sear assembly itself dictates the closing of the on/off and the releasing of the bolt. You can't change that relationship but lengthening or shortening the trigger rod. Making the trigger rod too long only prevents the on/off from fully opening and the sear from properly catching the bolt. Setting the trigger rod too short makes the trigger sloppy and may prevent the sear from properly clearing the bolt when the gun is fired.

Try the o-ring in the power tube

If it has the level 10 kit, add a shim. If not, you need a the power tube spacer that is the next size up.

You said it has a new on/off assembly? Doesn't the Micromag need a different length on/off pin, due to it's variance from AGD tolerances? Are you using the Micromag pin?

got it to work. just found the right length rod adjustment.
