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.

Bought this to use with the SBA3 pistol brace that I installed on my AR pistol build. Quality manufacturing of the castle nut made it a breeze to install. There are no sharp edges. Precision cut threads help to prevent galling. Plan on purchasing another one for my next build.
