ETA-  Contact made with RRA.  It’s getting handled, thanks.

I have a RRA lightweight 16” chrome lined midlength barrel I recently bought from PKFirearms.  I used this to replace an HBAR barrel on a factory RRA upper (RRA upper and BCG).

I assembled it to an upper and took it to the range for initial zero (good accuracy!).

Went to clean it and noticed on both sides of the bottom chamber lug and ramps appear the be missing metal material that looks like it broke away.  There was no metal within the locking lug area so my thought was that I initially got it this way.  Not sure if it is safe, so I took the barrel back off the upper..

Sent info and photos to Brian Frakes of customer service / Technical (over a week ago) but haven’t heard anything back.

Will RRA warranty this?
