Good day everybody,

Got this issue that has me pulling what's left of my hair off.

The Echo1 XCR uses a split mechbox, ICS style. I'm not familiar with this, but still...

The issue I have is that the gun will fire in FA and then seize up.

The motor still wants to turn, but something is stuck.

Now I did a bit of research and tried or verified some things before posting, namely :

-The motor works fine, it spins the lower easily when the upper is removed.
-The lower gearbox spins fine, I have not touched the shiming.
-Motor height adjustment is good.
-The piston slide freely in the upper, with the spring removed, and with it.
-AOE is ok

Now, before I dismantle the lower GB, if somebody who has encountered this problem could shed some light, it would be much appreciated.

Thanks,
