    Some may consider this damage “cosmetic” and find this information useless. Once their buffer reaches a point to where they consider it unserviceable, they’ll simply replace it.
    As a practical matter, I've never heard of (much less seen) a buffer that had to be replaced because of this level of wear.

    I would guess that this is because the wear is limited to only a thin layer of the buffer as eventually that "cutting surface" on the edge of the retaining pin channel no longer contacts the buffer, as the buffer is pushed off by the rest off the bolt carrier that remains in contact with a larger portion of the buffer and the "cutting edge" can no longer dig further into the buffer.

    I've been shooting ARs hard for about a dozen years or so and have never had any problems due to excessive buffer wear, but I only run tier one guns.

    I can't really see myself lapping the ass end of a bolt carrier, but I guess if you have the time to do it then knock yourself out.

    Thanks for your input. Like I stated above, there are those who will......“find this information useless“.

    It's impact marks from the buffer retainer that you need to look out for. Those will eventually cause the buffer to bind in the lower receiver extension if the retainer doesn't break first and are indicators of much larger problems with the rifle.

    This is where I have a problem... everytime I lap up a few brews, I'm not as concerned about cosmetic damage to the inside of any of my rifles.

    Different Marks on Buffer????

    Ive been shooting my AR build and noticed weird marks around the edge of the buffer face. It looks like the pin is hitting the buffer. I took it to a local Gun Smith with a good rep for black rifles, he said the lower is probably out of spec. That would not surprise me... its a ROGGIO ARSENAL. I already ordered a better lower and a DD LPK to go in it. Is it possible I put the lower together wrong. Also any tips on the latest buffer to run on a 14.5 Middy would be appreciated.

    Several Roggio Arsenal receivers were pretty far out of spec. They were pretty good about replacing them. I'd suggest calling/contacting them. The buffer detent hole on yours is milled too far back.

    Is the rear of your bolt carrier flush with, or slightly above, the back of the upper receiver?
