68 Classic mag leaking down the barrel. HELP!

[steve_81]

I just aired up my 68 classic automag and it shot good for the first few shots but then started leaking out of the barrel and wouldn't shoot. What could it be from? needs new o-rings?

[nevtangle]

Does it have the level 10 or level 7?

Start with a couple drops of oil, check power tube oring if it's a lvl7 bolt. If it's a lvl X bolt, your carrier oring is probably too loose.

Is the leak caused by bolt stick? How tight is the back thumb screw?

describe more in detail

[steve_81]

Sorry for the lack of information. The Mag has a Level 7 bolt and a classic valve.

[michbich]

Did you check the powertube oring and oil the marker?

[questionful]

Does the leak continue if you hold the trigger down? Do check your powertube O-ring.

Thanks for all of the help. I believe its just the power tube o-ring...since after i shoot it a little bit the leak stops for a second then when you start shooting it starts leaking again.

I'm going to order an o-ring replacement kit from AGD first thing tomorrow.

check to see if you have a rail bushing. If you don't have one try pushing on the back of the valve and shoot. If the leak goes away then you need to get a rail bushing.

you need a rail bushing anyway...
