Last play day I was taking my E-Mag apart to find out why it was leaking down the barrel.
I had lost the bumper, or so I thought.
Today I began breaking it down to clean and pack away.
The level 10 bumper had disintegrated and fallen into the trigger well and was keeping the solenoid from retracting completely.
Thus the slow leak that only stopped when I manually depressed the trigger.

Yep. Keep an eye on your level 10 bumper. They are known to get chewed up on some guns. Many people have had good luck in maintaining longevity by gluing them down.
