It is polished. It is so odd - every single shot is fine - when I auto trigger - it drops off or get erratic. Clean the bottom tube - works great.
I called Rod - on his advice I checked the hammer (same ID to the thousands as a stock NEW hammer) so I switched the sear lug.
Again, it shoots lazer beams now - we will see. I have no clue what I did to cause the burrs - it is a new problem - certainly not a factory problem.
If need be I will send it back to yall for a check up.
