Air Leaking Help!!!!

[KeYserSoze102]

So here's the deal, I bought a like new mag off ebay a moth or two ago. I put it all together (replaced the gass hook up, and checked seals) I go to play and when I gas up the gun it leaks like no other down the barrel. I go home and replace all the orings clean the gun and oil it up. I gas it up again, and at first it sounds good, I dry fire a few guns and then it starts to leak again! I am @ a loss, I am knida new to mags but I really can't concive of what it might be. Any advice?

Did you check all the seals? There are a TON of seals inside the actual parts, if you have the video WATCH IT its amazingly in depth, and the manual is really helpful for troubleshooting especially leaks, and it has a section for barrel leaks
