Decent kit - CMC Triggers AR-15 6-Position Mil-Spec Carbine Buffer Tube Kit

Lightweight and seems to be good quality. Only thing that stuck out to me as a negative is that the buffer is not round (a couple flat sections) so when those sections contact the detent pin it barely touches. This seems like it would wear over time on the face of the buffer and/or the pin. So I turned the buffer so that the springs tension holds it in a spot that makes the most contact but obviously with use, it can rotate.
