I recently picked up a used minimag. The gun seems to be in good shape, but i went ahead and striped it down, replaced all the o-rings and lubed it liberally (with air-gun oil, and vasaline on the spring pack assembly). After rebuilding the gun, I can't get it to fire more than one time without the bolt sticking. So after researching a little bit I replaced the power tube spacer with a .220 (it had a .215) that didn't fix the problem so I went to the .225 and once again no luck. I have tried everything I know to get it right and nothing has helped. The gun has no leaks whatsoever when air is supplied (I submerged it in my bathtub to make sure lol). It seems as if the bolt is sticking on the powertube maybe??? But when I take it apart it seems to move pretty freely. For those of you who will ask the standard questions here are the answers. I'm in Southern California so weather is not a factor, its a blistering 72 degrees outside right now, I have both Co2 and Nitro set ups and niether make a difference, and yes I have tried it with and without paint. I would appreciate any info or suggestions that you folks (the wise and allknowing magmasters may have because I'm a noober at the mag stuff) Thanks in advance!!!

Welcome to AO!
Have you tried cranking up the velocity nut until it vents, and drop it down a bit until it stops?
-
The best I can think of is to do what Miscue advised.
That's what I'd do.Comment
-
yeah i did that a couple of times now. Oh well I've taken the thing apart so many times that i now know where every part goes lol. I'll figure it out sooner or later i suposeComment

Try firing it without the barrel on.

the bolt is sticking on the power tube i assume. I can take a dowel and reset the bolt ansd refire but it won't reset itself.Comment

When you replaced all the o-rings and did your gun cleaning, did you replace the bolt spring? A weak bolt spring could cause bolt stick issues.Except for the Automag in front, its usually the man behind the equipment that counts.Comment

yeah when i rebuilt the gun i replaced the spring and every o-ring in the gun. I have tried it with the barrel on and off, nothing seems to help. The gun is very simple so I'm runing out tof suspects, I am now focusing on the trigger and sear. The pin that the trigger pushes up on the valve (that should be vary light or should it have some tension on it???) mine seems to have tension on it, it won't slide freely very easily. I have even reversed the pin a few times to see if that makes a difference, but to no avail.Comment

Did you adjust your trigger rod?Comment
-
Yeah I'm messing around with the rod length right now. But nothing yet has worked and I'm running out of air (again!) The bolt seems to just not reset itself, I can easilly reset it with a dowel, I mean I barely touch it and it resets.Comment

Hmm. Had a similar issue with my son's emag, turned out the tip of the bolt was rubbing on the inside of the spring.
Haven't really worked with a L7 bolt so I am not sure what to say about the spacer length, except that if going longer didn't help, can you go shorter?Comment
-
Try a longer powertube spacer. Go to a .230 or .235 if you can.
Is the bolt a stock AGD bolt or an aftermarket bolt?Except for the Automag in front, its usually the man behind the equipment that counts.Comment

The bolt is a stone stock AGD unit, the whole gun seems to be stock equipment. I have ordered a spacer kit so maybe that will work. I also spoke to an AGD tech on the phone and set my trigger/sear pin to the correct length of 50.68mm or 1.995in (yeah yeah! I'm into motocross so all my nice tools are calibrated in metric lol). If nothing else works i just may have to buy a new X-valve
the wife will love me for that 1 I'm sure.

Well if you get TOTALLY frustrated, I would be more than happy to fix that marker for you. Sounds like you have it down pat though. Let me know if you need any help with it.
