Mag problems

[Poseidon]

ok, here is my problems.

I have two vavles. I have an old 4 star minimag vavle, and a standard mag vavle with out stars. The mini mag vavle leaks out of the overflow vavle really bad. I chacked the o-ring on that big brass thing behind the reg, but it look out. I'll probably end up changeing it and seeing if that works, but the pressure wasn't set too high or anything. Is there any thing other than the o-ring that could be the problem.

Then onto the next vavle. I have no clue whats wronge with it. I have tried all sorts of spaces, and it still leaks. It really pisses me off. It will sometimes go into a full auto but it doesn't cycle, the bolt just stickes open.

So here is the real dilema, I put the front from the minimag onto the back from the standard vavle and it worked great so I know it's not an on/off problem or a trigger rod problem. Im also getting a bit of bolt stick where the botl isn't fully relaching onto the sear. Is that just user error? Short stroking? Im not used to my mag yet, I just got it, but i am pretty happy with it.

Any idea would be greatly appreciated.

well first off the old minimag valve has the symptoms of a bad seal inside the high pressure piston. you said you looked at the o-ring on the outside? well did you put a new reg seat in? the reg seat is the big fat "hockey puck" between the front and back halves of the valve body.it's the first thing that would cause this symptom. put a new reg seat in, if it still has the problems you described then the seal inside the high pressure piston is bad. don't even bother taking it apart, just order a new high pressure piston from AGD or get it from your local store. since it is an old valve this is not out of the ordinary. after you replace it you shouldn't have any problems with it for many years.

now the second one you're not making sense to me. you said you put the front of the minimag valve onto the back of the standard and it works fine? don't do that. your not really trouble shooting the standard valve when you do that. that just proves that the high pressure piston in the minimag valve back half is bad. we already know that. are you putting both of these valves in the same body? is there a power tube o-ring inside the power tube? did you try putting a new one in? is the bolt worn on the edge that makes contact with the sear? does the on/off pin move freely? is the velocity turned up to normal range?
try checking these things and post again.

After i wrote the post i thought of that piston seal, and that did the job on the minimag vavle. The problem with the other vavle was the trigger rod. It was too short. Now i get to have fun trying to get my hyperframe to work with the vavle. ohhh, joy. Im still haveing a tiny leak (with my benchy 2x). When i pull the trigger slow I will get a short, small leak right before the bolt releases. Is this comon? do I just need to get used to the trigger and pull it faster.....

[Poseidon]

any tips on hyperframes?

[Predater]

pulling the trigger slow is what is causing that leak. pull it fast and no problem.

[the electrician]

yes

thats completely normal. basically you are letting the bolt move foward slightly. the power tube o-ring then starts to come unseated from the shaft inside the bolt which causes the small leak you hear. but since there is no benifit from pulling the trigger slow, why bother. but now you know.the proper way to pull a mag trigger is quick and snappy.pull fast and follow through, then release all the way quickly.if you short stroke, the gun will shoot crappy and break paint, just like any other gun. some people use as long a power tube spacer as they can(without the gun leaking out the power tube) because it makes the trigger feel softer. but I hate that. It makes the gun shoot crappy and inefficient in my opinion. I prefer a really short spacer. while this may make the trigger feel a bit stiffer, the gun's velocity will be more consistent and it shoots better.
I don't have any experience with the hyperframe. I can't see payin that much for something I could make myself. but that's just me. I have a homemade e-mag. I also designed a pneumatic trigger mod that works really well.
good luck with the hyper frame
let me know how it goes.

No thats NOT completely normal. It causes prefiring one of the leading causes of mag inconsistency and ball breakage.

It should not leak at all until the bolt is completly released. What you guys need are some smaller powertube spacers. Stock is a .220 try replacing it with a .215.

As for the valves the first one leaking out of the back is probably a broken blow off saftey relief valve. Call AGD for a replacement reg piston.

As for the bolt stick problem change your bolt spring. If that does not work try a larger spacer.

As for the hyper your best bet is to send it to centerflag they will fit it perfectly for you.

well i got the hyper frame for free :)

It is double and triple firing. I think it's just the on/off stem isn't long enough. I have heard of that problem before. Im gonnna call them and get a longer one. That should alleviate that problem, and all will be good.

Thanks guys.
