Thank you Polecat! Very helpful. Looks like Zi have the EG.
With respect to the misdeed - as others have indicated, I think it’s operator error… Don’t think I was operating the lever with enough speed/force.

I currently have the rifle apart and will be creating a new post seeking comments pertaining to the carrier assembly from this same gun. It has a split or notch carrier body in which in this case the carrier spring tail is retained. I was informed that the spring tail fit in a retaining hole at the end of the carrier. Interested to see if anyone has seen this before.

Thanks again for your response!
