Glad someone makes them in different colors - Guntec USA AR-15 Complete Anti-Rotation Trigger/Hammer Pin Set

I've bought a few of these and will likely buy more for future builds. They work great and they make all the colors I need for custom looks. They are a breeze to install with the provided punch head and give you the peace of mind that your receiver pin holes don't ware out and become sloppy over time in addition to anti-walk/rotation. A must have on any build for me.
