I have a ton of 5.45x39 ammo.

I have a S&W 5.45x39 S&W upper.

Every time I fire it puts a gas of jet into my eye as bad as if I was shooting suppressed, even though it is not suppressed.

It seems like it is grossly over gassed.

Given teh huge amount of 5.45 ammo I have, I am committed to making this work.

Has anyone else had issues with 5.45x39 S&W uppers being over gassed?

IF this really is the problem, then an adjustable gas block should be an easy solution.
