Good product but may need fitting

I would buy these again, now that I figured out how to install them. My barrel had a slight bump at the end of the threading, which in all honestly is probably better than an undercut behind the threads. I barrel will be stronger for the heat that will be generated in this area. I used a Dremel tool with a small grinder bit to add a chamfer to both ID sides of a washer and it worked well and the washer seated flat to the barrel end. I probably only needed to bevel one end of the washer but did two. Next time I will only do one side. I also tried using the Dremel to grind the ID of the washer slightly larger but after working on one washer and increasing that OD by @ .010" and it still didn't fit, I knew that was not the problem. Originally, I used a toolmakers chamfer tool to chamfer the inside edges of the washers and that did not make the washers fit flat. I thought it would be enough, but it was not. My original inclination was to add a bevel to the ID but I had to step through the process to prove it. I will use these again.
