Midlength gas tubes - Aero and Damage Industries
It’s been probably a couple years since I assembled an upper. But I’ve done more than a few, and I don’t recall noticing this issue before. Maybe I just didn’t notice.
Issue:
The Aero gas tube clearly makes contact with the CMT barrel nut. It does not “float” over it. I grabbed the Damage gas tube that I have as an extra, and it actually was now obviously making contact than the Aero was, with some pressure.
A little googling and a Criterion video point toward bending the gas tube as a valid resolution for this.
Anyone else bend their gas tubes? Any tricks to it?
I’m looking to get the most repeatable performance I can out of this upper, so I don’t mind doing it’s. Just new to me.
