    I guess everybody has to get their idea from somewhere. It's amazing how far ahead of their time Stoner, Kalashnikov were.

    Gas port erosion is one of the most over-worried issues in the AR realm. It's somewhat self limiting, and the throat will be gone 10s of thousands of rounds before the port is problematic.

    Ive heard different types of lube can impact port erosion

    Ain't that the truth.

    Thanks for the focus tip!

    As others have noted, the gas port erosion and worn leade have not put much of an accuracy dent in my 16" Noveske CHF CL barrel with ~7K rounds. Still getting good groups with IMI 77, BH 75, and XM193 @100Y. Also easy hits to 500Y steel which means it's still my primary reliable go-to AR after all these years and many other contenders in the safe!

    I guess my borescope is mostly for fun as opposed to a diagnostic tool I have any skill with

    As the gas impinges on the edge of the port, it will abrade off minute particles, which will then travel down the barrel. So, before the gas port, it is mostly hot gas with a few combustion particulates, after the port it's more of a sandblast effect.
