Re: 3 beta mag and a M16
I'm surprised that it only lasted 300 rounds until it suffered that level of deformation.
I've had a gas tube so hot that it was glowing before.
About 250-300 rounds quickly, not really sure.
No deformation however, but it took on a nice colorful patina.
I wonder if there are substandard gas tubes floating around out there.
It wouldn't surprise me if there were.
Thanks for sharing.
