Kns non-rotate trigger/hammer pins - KNS Precision AR15/M16 .1555 Diameter Gen 2 MOD 2 Non-Rotate Trigger/Hammer Pins

When I purchased my first drop in trigger, I purchased these KNS pins and was quite happy with them. I later started a new build and decided to explore other brands of anti-roll pins and was not pleased at all. The locking face plate fell out of place and slowly did the pins. That ruined my day at the range and later that evening, I got onto Optics Planet and purchased 2 more KNS pins.
