Help! my gun leaks

[Food is Yummy]

k heres the deal...i was at the feild n I let someone see my mag... (pretty stupid)... well that idiot gased it up and was firing liquid co2 through it. i think he blew an o-ring or sumthing i not sure but everytime i gas up my mag, air shoots out like crazy out of the back of the valve


can some one help n guide me through wut i have to do?

If it's leaking out of the back of the valve, the velocity may be too high, try turning it down. And please, tell us more about your marker, SN, valve type, air tank type, input pressure, lvl 10 or lvl 7 or other, etc. We need a LOT more information in order to help you effectively. Thanks.

well i dont think the velocity is too high but i'll be sure to check that


as for my mag

68 automag class
basically stock exeopt for the barrel
68 classic valve
stock bolt

my tank is 68/3k with a nitro duck reg
the gauge says 3k so im not sure if thats the input or not

thats all i kno
hope that helps

first, that 3k reading on the gauge is your pressure in the tank. when that gets down to ~1000 you want to have it refilled. your tank will always output ~800-850psi

as for the leak, there is an oring(see image below). its the piston oring. that is the typical cause of the leak out the back. on the top row, there is the velo nut, the spring pack, the brass piston and the piston oring. replace this nad you should be set

thanks alot

no where would i find a piston o-ring?

If you don't have a parts kit, you may want to buy one. You could try calling up AGD, and either ordering one, or seeing if you can get the part you need. I'd just splurge and get the whole kit, you'll need another o-rin sooner or later.

If you go to www.airgun.com, their tech section has this exact diagram, but it's linked to the parts in the store. Say you needed a new bumper, you click on it in the diagram, and it sends you to the store, looking at the exact part.

I'm not sure if this would help you or not, but I have a minimag, when I installed my Level X bolt, I wasn't able to chrono up past 260 fps. Massive leaking out the back. I changed the Regulator Piston Assembly upon the advice of an AGD tech. It workd like a dream. Do you have an older mag? You may want to try this if you got an older one. Now when we play down and dirty woods games my 'Mag has been outperforming my friends Cockers. Their guns work like a dream when clean, but halfway into the day they both start complaining about chopped balls and clogged this and clogged thats. LOL. I love Autocokers, but when the maintenance gets in the way of a good game...well...thats no good either. When me and my friends chrono up to the same range I can honestly say that I would take a mag over a cocker any day of the week and twice on Sundays! Anyhoo better yet email AGD, they'll get back to you quick and include a link of anything that you might have to purchase. Good luck!
