Never touch the bolt head face. Just the edges that need a little POLISHING..
I used my file very gently and here it is.

After repeating this process {of using a marker and filing the resistance points} about two times, this bolt head is rather smooth

I also had to fix/smooth out the receiver/Trunion

Here is the starboard side.
Note - I have smooth out the surfaces leading into the bolt head locking area but NOT decreased the locking lug face area
