Why would this be? Inside carrier looks good, replaced bad ring. It made it 8rds and ate another. Any ideas would help. Please and Thank you.

Did you put the rifle together or was it purchased new? Is your gas system all setup right?

New from manufacturer? Call them. Sounds like you have a rough area inside the bolt carrier that is wearing them down, and that will need to be replaced. Probably a bad chrome job on it, and it can be difficult to see in there.

The recess on the bolt where the gas rings are placed may also be out of spec and forcing the ring outward. How is the bolt movement in the carrier.

The bolt is snug inside the carrier. Its a lot tighter than my other ar.

The bolt should slide in and out with resistance, but still smoothly. It should also be able to stand up under its own weight when stood on end bolt down. Anything outside of normal, call the manufacturer.
You've been good about not posting their name here until they're given a chance to fix the problem, but it sounds like now is the time to make the call and see what they do with it. Anything you do to try to fix the problem will likely void whatever warranty they do offer.

I've seen this problem before.
First and foremost, inspect the inside of the bolt carrier. Make sure that the inside is chromed. If it is not chromed, that's your problem. If it IS chromed, use a light to inspect for any irregularities or rough spots in the chrome. If not that, look very closely at the inside of the carrier around the bolt cam slot. Use a magnifying glass and a light if needed. Look for lips, burrs, or chunks of metal. Also look at the gas port from the inside and see if anything is sticking out from there. There is a 95% chance that the problem you describe is being caused by the rings catching on something inside the carrier. A couple big-name companies have previously put out batches of bolt carriers without chrome inside the BCG (just poor QC, not by design).
The easiest way to check is to run your bolt in another BCG, or to run another bolt in your BCG. That will give you your answer. I would bet dollars to donuts though that the problem is with the inside of your BCG.
