Leak down barrel - 68 classic w/ ANS back

[Reflex0283]

picked up a mag last week, it worked for a while then I think it blew an o-ring somewhere. I partially tore down the valve and didn't really notice anything, any guesses as to what it might be? Thanks

Possibly the o ring/seal in the bolt itself. I’m not an expert but I think that’s causing the leak down the barrel.

Unless its from someone you trust assume pretty much any used mag you pick up will need all o-rings replaced, regardless of how they look. unfortunately AGD site is undergoing a change of hands and is down. however if you email sandman@airgundesigns.com he should get you taken care of with a rebuild kit. get some outlast gun oil - its the same as teh AGD lube from him to - Mags love to be doused in the stuff.

If you hold the trigger and the leak stop, it's the power tube oring
010 urethane oring

Thank you! This is exactly what is happening

I agree with this, just do a full rebuild with a kit from AGD and don't go light on the oil

Realize that it will likely need some breaking in after you rebuild it though

The AGD website seems to be down?

[Swedgin!!]

I’ve emailed AGD about a month ago for a rebuild kit but he’s not taking orders until the website is back up and running.

Check Oregon Paintball. They usually have a fair amount of items. The website is glichy but you can call them or email.

Automag like urethane oring especially for the power tube oring. Once rebuild it will last year with only a few drops of oil each time you play.

Order a bunch or 010 urethane oring they are really usefull
