Automag Cycling Problem. Please Help.

Hey guys I have a minimag run with a lvl 10 bolt and a 3.5oz CO2 tank running straight through the VA, through a steel-threaded hose, to the valve. If I try to shoot it past like.. 6-7bps it will "lock up" and not want to fire. When I pull the trigger, I can tell it wants to fire because it makes a noise and I can feel something move but it wont fully cycle. To fix this, I have to hit the back of the valve with the palm of my hand. After doing that, it'll cycle fine again.

I had a local tech look at it for me and he changed out a few parts and the spring but it still acted finicky.

So what seems to be the problem?

Any info would be greatly appreciated

You might be freezing the valve.

Try it on HP and see how it goes.

my first thought is that cold CO2 from all the rapid firing is freezing o-rings inside the valve causing binding. Then when you hit the valve (while not firing) it allows time from them to thaw and knocks them back into place.

My other thought is that the CO2 is distorting (shrinking) the level 10 carrier o-ring causing it to be tighter on the bolt which would cause binding

but, I am far from an expert on such things

I've never been able to get more than 4 or 5 bps out of a classic valve with CO2. I'm surprised you are getting as much as you are. I would go with HPA if you need more bps.

Where are you in SC? Seem like my brother and I are the only people I see in the midlands with Mags.

Is your rail bushing in there? Along the same lines, make sure your field strip screw isn't coming loose and has the urethane washer on it. Both of those often act up regularly after you start playing.

Cool man, PBC is awesome. I was down for the Chosin event last fall but I didn't see any mags. I'll keep a better eye out next time.

You may know GQ - he is the head of my teams Charleston branch.

Feel free to hit me up if you need any more advanced mag help (locally). I have 6 or 7 of 'em and I've gotten pretty good at getting them to work.

I loathe mags on CO2.
I love them on HPA.

Night and day.

my mag basically refuses to run for more than 5 trigger pulls on CO2. HPA is all i use with my mags anymore (except my pistol mag loves 12g's)
