I had a few of these knobs turned up as I was getting tired of always needing a wrench to remove my cheek piece. They are CNC turned from 304 SS and have Black Cerakote finish on them, if anyone is interested they are $35ea shipped. Pictured is one installed in my Manners TA (stock not included). I have some that are 1" and some 1.25" to fit different stock widths.
