I have a complete 1999 Bushy lower (6k rounds on it) and noticed that I can definitely see the hammer pin rotating when cocking the hammer back. How bad is this? Do need to get a .155 KNS anti rotation kit? And should I get this kit for my "in progress" Stag build in order to avoid this issue?

ETA: Are the KNS Heat Treated pins any better than the standard pins that came with my Stag LPK?
