I have a 10.5" .300BLK upper from them. Running a no-frills PSA bcg and haven't had any issues to date. Probably 500-ish rounds down range.

Not endorsing, by any means, just relating my experience with RF. For the money I have in it, I'm happy with the performance. Hope the OP gets things worked out.

first issue was the cam pin broke replaced it now the BCG wont engage gets stuck just before going in to the lugs.. got a brand new fail zero BCG same issue with less that 20 rounds down the barrel total ..
upper is a 16" SS barrel and gas tube chambered in .223 wylde.

Only ammo i have used is American Eagle .223 55 grain

Does your upper have gouging in the recess for the cam pin? Was the original cam pin that broke have the correct dimensions on the head? This sounds like multiple pieces not in spec.

Bring it in to Bowers and we can look at it.
