I have the gen 1 KNS pins
(Oversize) in my primary, with a RRA NM 2-stage, only because the lower is old as dirt (SGW, from 1983) and the pin holes were somehow very worn. Very solid.
I agree, generally not necessary in most.

RA highly recommends using the KNS anti-rotation pins. If you have an aluminum rcvr, do the following:
Insert the trigger assembly.
Per your instructions, adjust the set screws so that they are just kissing the bottom of the rcvr trigger housing "well". It might take 1 or 2 attempts.
When satisfied, install the KNS / other brand anti-rotation screws. That's it.
Before you install the assembly, following the instructions for set screw adjustment, "adjust" the screws to make sure they indeed rotate. Before insertion, make sure they are flush with the trigger assembly housing (cassette) and march on.
Just ready to get this thing together and start plinkin’.
It’s weird that RA recommends kns pins over their own anti walk pins.
Rise Armament states:
KNS pins recommended (available here) but not required. If you do not use KNS pins, be sure to follow step 8 in the installation instructions linked below. The set screws should be used with any trigger pins.
Here is the installation without KNS pins:
Step 8
There are two small setscrews located on the trigger system under the hammer springs. Lift or shift over each hammer spring and use a 5/64 Allen wrench to snug the setscrews to the floor of the receiver. Do not over tighten, as this will change the poundage of the trigger. This step is necessary for the weapon to function properly without KNS pins.
