Thanks for the feedback!
After my last carbine class, I noticed the pins were spinning more freely and the trigger pin was slightly protruding on one side of my LWRC.
I may try a set for this reason - but sounds like it's a waste to buy a set for every AR.

I don't think they serve any real purpose. If you must have a trigger pin upgrade, get the oversized ones; they should fit snug and eliminate rotation as well. Plus they only cost $3.50. I traded my anti-rotation pin set for a Magpul BAD.![]()

so far I have never seen pins "walk out" on any anodized lower that is in spec. I do know the the two epoxy mix that makes duracoat are slick in nature. and KNS pin's are like 40 bucks or less so kinda cheap insurance. I know when I did my first lower and tested it in the white and the pins stayed. then when I duracoated and the pins walked I broke out the calipers to make sure everything was in spec, and it was. so...i blame the epoxy![]()
There is a lot more stress on the pins from a blowback system, even .22.

KNS pins are retarded nonsense. Just look at some of the other idiotic products this company makes.... crosshair front sight posts for example.
If you have pins walking out, you have other problems.
