Aftermarket hammer and trigger pins kept moving out of lower receiver, but these keep them right where they’re meant to be. Install was easy but took a little time to do with suck small parts. Wish I would have gotten the stainless set but you can’t go wrong with black.

I use these pins on every build I do. Top quality product, and they come in all diameters you need for any AR. Very easy to install, each of the two screws are already coated in loctite. These pins very important to use if you use polymer lowers where trigger pins may loosen and back out over time. One pin is is slotted and one pin is screwed in place to prevent backing out and rotating of the pins both.

This was a great product, it was very easy to install with the provided guide pin. I would definitely recommend buying if you are looking for one, serves a purpose and adds a different look to your gun.

I bought this for an AR 80% with anodizing of unknown quality. I don't want the holes to open up, so I installed the KNS pin set. It was easy to do, but I would watch the KNS video on youtube to get a better understanding of the process. You can install the pins without watching the video, but watching it makes the process faster and easier.

If you've ever experienced trigger failure because of a retainer pin walking out on you, then you know this is a must have item. I had it happen only once and spent a lot with my local gunsmith to repair the damage which ultimately ended in selling the rifle. Since then I've used KNS non-rotate pins on every build. Is it really necessary? Maybe, maybe not. But I, for one, am not willing to sacrifice any AR build to anything less. These kits just work…oh, and they look cool too!

The best anti-walk pins. They replace your Mil-spec pin for one that won’t come out when you shooting they are a must .
