Something in the carrier group is hitting the inside of the upper and I was wanting to know if this is normal?

Hi All. Seems like a lot of people are looking at the images, but have yet to offer any suggestions. Has anyone seem the same damage to their upper as I have ?

Have you disassembled the rifle and run the bolt back to see if there is anything catching? During the 350 rounds, did you have any issues as far as the bolt going into battery, any FTF or FTEs? Does the bolt appear ok or is it missing a chunk?

I think its wear from the little nubs on the CH.

Stoney, take a close up look at the second picture. That looks a small piece of metal is missing, not just casting that had worn off. I could be wrong.

The rifle runs great, I haven't had any of the issues mentioned. I had just returned from the range, and noticed this while I breaking down the rifle to clean. I thought at first it might be from the charging handle, but it's not in the same area. My guess is that it comes from the tee post that guides the bolt as it extends and retracts. I see no indication on that post from impact, but I wouldn't expect to as its harder then the alumn upper.

It's more then the coating, it's actually removed material from that area, and pushed a burr into that cavity

How does the cam pin on the bolt carrier group look? That's obviously what has done it but shouldn't be doing it. Could just be a bad spot in the aluminum that gave up. I can say LWRC will certainly take care of it. Have you tried calling? I never have much luck with emails, they seem to always end up in spam. Everyone I've talked to has been great to deal with.

I got a note from Ed Westerfield @ LWRC he thinks it's the cam pin and he says it's just normal wear. I find that difficult to believe, but I don't know if I have other options for second opinion. Here's Ed's response.

Rob,
From looking at the pictures it appears to be cam pin wear which is normal wear and does not present a problem. Some uppers will show more than others. If you have any questions please contact me.

Respectfully,

The cam pin looks brand new, but it wouldn't show damage as it's harder then the alumn the upper is made with. I do agree that it shouldn't happen, but LWRC says it's normal.

Seems to me that something is out of tolerance, weather it's the upper, the cam pin, or some other component of the carrier group.

So I'm new to the AR platform. My 20" REPR being my first AR style rifle. I have been involved with firearms most of my adult life. I understand normal wear, but when a grove is gouged into the part I believe it is not normal. If you guys read Ed's response to me and believe this is normal please let me know. We've paid a lot of money for our REPR's and the see this damage, I'm disappointed.
