I have some KNS gen 2 anti-rotation pins, but they are not installed yet....still debating on how necessary they really are...

Not at all on a semi auto gun.

I would only consider them necessary on a $15K registereed FA receiver. For a semi auto gun you will not likely have enough wear to eggshape or wear out your holes. My wife's 9mm AR has well over 7,000 rounds through it without the use of KNS pins and her's is running fine. I will put a drop of oil in the pin and call it good.

Most people use them to keep the pins from walking out but if the lower is assembled correctly they never should walk out. Most problems with the pins walking out come from two causes. One is the hammer spring is underneath the trigger pin, the legs should be resting on top of the trigger pin. Second is the hammer spring is installed backwards. Installing the hammer spring backwards can also cause light primer strikes.
