wheres the leak?

[StoneSolid]

my guns leaking, its somewhere internally i think. it sounds like its coming from where the bolt hits the ball. and when i cock the bolt back the sound changes from a noticable hiss to a very dull hiss. any thoughts?

Have you tried anything yet?

Most likely culprits, valve o-ring (front) or cup seal.

Cup seal probably get away with just oiling it and firing it a few tiems. If it still does it put a new one in.
