Leak down the barrel?

[Stix]

I have an emag, with the standard E-mag valve and on/off, as well as level 10. Sometimes, more often than not, the gun starts leaking down the barrel. When the trigger is fully depressed in manual and hybrid mode, the gun stops leaking. The gun looks clean and is lubed. However, after a string it will start leaking down the barrel again. Anybody have any suggestions? Thanks in advance.

Remove a shim from your LX bolt or go to the next smaller carrier.

Thanks, looked like that worked.
