ok my mag is locking up and wont let my air though(im using co2)(dont ask why) (ok its cause nitro isnt around here and i play woods) anyway when i put the air on i shoot and after about 50 rounds it wont shoot anymore and the pin that pushes the trigger up wont pop back to the trigger. and when i try to take the co2 off it locks up and then pretty much blasts off the end? can any mag owners help me

Well, as you know co2 isn't good. But with your current situation being in the woods, that isn't a good thing. First off. take your " on/off" assembly out ( it is the part which the sear pushes up and down) and check the orings, and lube it a bit if they aren't screwed. That could be a factor as to why the trigger rod doesn't push back correctly. Also, just make sure that all the other orings aren't broken or cracked, sense the co2 sometimes freezes them...

hey im gonna take this apart right now and tell you what is going on but hey can you sit tight ad help me cause ive had the mag sicne when it wasnt a classic mag

[chinowithamini]

does it matter if my bumper is a lil cracked?

[Maggot6]

Eveyrthing matters..

Alright, take this into account. Very high pressure air (comparing to our current atmosphere) is trying it's best to run through a very small space. So, you take that, and it finds that little hole. co2 Keeps building the pressure right there, in the crack of your oring.. your mag screws up. Although, it also depends on how bad the crack is...

[chinowithamini]

well its the bumper. is that even a seal

[wanna-b-ballin']

the bumper doesn't seal jack didley. its there to keep the bolt from smaking on the valve. metal on metal hitting repeatedly isn't good.

if its cracked though, replace it.

that crack wont matter but prolonged use will kill it and could dmage the valve after awhile. Are you sure your not getting liquid into the gun can you explain your problem just a bit more its kinda hard to understand what your getting at by your discription.

[Spacemanvic]

Rifts right. If you have a co2 bottle on your bottom line, you could be getting co2 in the vlave, which will do all sorts of unholy stuff to your mags AIR valve.

My old mech mag config had co2 via a remote, then that ran into a bottom line, which ran up to a vert mounted expansion chamber, then through a short SS hose into the valve.

Keep liquid out of your AIR valve!!
