    I've got a brand spankin' new S&W M&P15T that has less than 150 rounds through it, and it is doing the exact same thing... the scratches that are appearing on the buffer aren't deep, you can't feel them with your skin, you have to run your fingernail across it to even feel it... I hope it's nothing to worry about... I was thinking of getting one of those buffers Brownell's makes, the ones that reduce cyclic rate, bolt bounce, etc... was wanting one simply to make the components take less of a beating... I got worried when I seen this thread, I've got 3 more AR's, and have owned several, but I finally saved up and got my "dream" rifle, the M&P 15T.. I hope it's not been made substandard...

    The last one is definately caused by a burr on the back of the bolt carrier.

    The funny thing is I can't feel a burr on the bolt carrier. There is that shiny spot near the cutout that might have been a burr that was later removed after the test firing? That's my guess anyhow.

    Yeah, there's no burrs, marks, or even discoloration on the entire rear of my bolt carrier - yet when I close the upper, the BCG still touches the buffer slightly and pushes it back, seems like the buffer (under firing) still can just barely touch the buffer retaining pin... at least enough to mildly scratch it.... that must be why they sell those polymer buffer protectors at Brownell's... some people's rifles must be a little tighter than others... I'm not going to worry about it... From the information I've been looking at online, the buffer can withstand several thousands of rounds of this scratching and still show no detrimental effects other than cosmetic... I hope I'm right.. or else I must be ruining a $1375 rifle.
