leaking down the barrel classic mag

[devolve]

Level 6 valve. with a level 10 bolt. ULE body. Original sear. Double trigger frame. There is an air leak down the barrel. Not alot,very small. If I touch the trigger the air leak stops, let go and it comes back. It also doesnt leak all the time. After I shoot it 3 or 4 times the leak will stop then will come back. I had the sear adjusted and it fixed it for about a day. Any help would be greatly appreciated.

You need to change the carrier size of the level 10 down a 1/2 step using the same oring.

And what do you mean you had the sear adjusted?

The sear is adjustable. The front peice is threaded to move back and forth. I moved it up so it would just touch trigger. That way the leak would be gone. But it only worked for a little while.

Thats the sear rod. Do NOT adjust that! It will screw with the timing of the sear, and can result in problem. Make sure it's the same length it was originally-
