maybe the cheap ones you buy , but the ones I get from stag are HARD. I COULD NOT DEBUR POLISH SMOOTH.
my experience first hand not a story on the net.

Is quality brass worth it in a AR platform?

It's all in the tools you use. From what I can find the ones from STAG are 4140 or 4150 just like their barrels. you can see from the chart that 4150 is maxed out in the 50's for hardness and realistically they probably bring it back down into the 30's for toughness. At work we use cutters, not grinders, on prehard material like A2 that is up into the 60's without any problems. you can't use HSS cutters on that hard of materials just like you can't use your average hardware store files on something in the 50's. A piece of bar stock and lapping compound will do wonders where normal files tap out.

Well I guess now I have to do it lol. I have a busy week this week and next week is deer season so it might take me a little while to get to it but I'll be sure to follow up with my success or failure based on my above theory.
I have never been able to do it, so yes I/we would like to see if you have success and what it takes.
pictures please/ tool list

No issues polishing the barrel extension on my barrels, from cheap bca, to criterion. When you use the right tools, and know what you're doing it's not difficult. Barrel extensions are not hardened to anything on the Rockwell scale that is difficult to work. If they were they would be brittle, and that wouldn't work out too well for their intended use.
