AR-Stoner 6.5 Grendel barrel short chambered.

Lets start another thread on ways to polish the throat!!

I would think that it wouldnt be too hard to use the measurements from saami grendel print, to make a rod with the shape of the throat on the end, and with that in a drill, using some lapping compound, to resurface the throat and polish it pretty easily. Or maybe not use a drill, just spin it with your fingers. Wouldnt take too long with different lapping compound grits.
