Default Breech Block surface

Just a little something I found was that the firing pin port in the upper reciever was swelled enough that when you rub your finger in the groove you could feel the raise edge of the hole where the firing pin extends, after taking a finger nail file and polishing the hole for a bit the swell was no longer able to be felt. Also after cleaning the tactical ammo indicator bracket had some wear, at the point the ammo first contacts when chambering a new shell, I also used the finger nail file to polish this point as well to smooth any rough edges, after doing those two things the problem with feeding shell after shell after shell was solved, each new shell chambered like a brand new pistol without issue.
I remember commenting on a previous post about failure to feed. The OP included some pictures and I suggested that they seemed to indicate that the cartridge was dragging on the breech block. I can't find the thread now and don't know the final resolution.

Maybe shanelassiter30 is on to something.
