Ss & nitride thats well machined - KNS Precision Safety Detent

Ive seen acouple reviews about rust & inconsistent machining but ive used KNS detents, plunger, anti-walk pins, etc ... to build 2 different guns and so far I haven't had any issues with KNS products. I like that their SS and Nitride dipped which not too many are and thats why I keep going back to KNS. Plunger snd detents when coated in Mil-Com TW25B grease or Slip2000 EWL 30w are extremely slick and provide a great snap to the safety selector. Takedown pin detents and bolt release plunger also feel great. So far only con for me is that these little parts can be quite pricey sometimes depending where their bought from.
