View Full Version : Very strange gas problem.

Manufacturer is investigating but has found nothing.

I shoot roughly 30k rounds a year and have 4 of this same rifle.

Anyways... rifle in question is a ZEV (mega arms) factory built rifle. It has zero malfunctions and is very accuarate. The problem is that when the rifle is cold gas pours out of the bolt catch. Exactly like if i were to be running a suppressor. After 2 or 3 magazines it stops doing this. I cannot come up with a reason for this and neither can anyone else it seems. It is bad enough that it makes the rifle hard to shoot. Any ideas?

Did you swap BCG and see what happened?

Something is loose, it gets hot, expands and seals. I'd think gas key is most likely, even if it feels tight to the fingers it may not be "sealed"

Do you mean the ejection port? Makes the rifle hard to shoot due to gas to the face?

Run a wire through your gas key, check your BCG and make sure port holes are clear

I would look at the gas key. Sounds like it is loose or simply isn't sealing until it gets warmed up

New bcg has solved the issue

Are you sending the BCG back to ZEV?

If not Permatex Form-a-gasket Aviation 3D. While you are at it might as well trade out the machine screws for the O.C.K.S.
