C-H-A-East's Review of Guntec USA AR-15 Castle Nut For Car/M4 Buffer Tube

I received a castle nut from a friend and it had burrs. I definitely needed a replacement. I compared several on the site and ordered two different. This one worked perfectly for my needs. It matches what I have nicely, too.
