LX issue with leaking air

[rkjunior303]

hey everyone..

trying to fine-tune my LX and i'm getting a slight leak down the barrel.. If I push on the bolt it stops but then once i start firing i get the slight leak again.. The o-ring in the powertube is broken in and right now i'm using the red spring, 2 shims, and the carrier with one line on it.. What do you reccomend? First time really teching the LX... Thanks!

You could try cutting down the long spring (since it's probably useless to you anyway) so that it's just a little harder than the red one, that extra pressure might hold the bolt in enough to stop the leak. I had a hell of a time getting my lvl10 perfect the first time until I figured out to cut the spring down. Remember to cut in small increments and test every time.
