These AR15 anti walk / anti rotation hammer and trigger pins are what you need to keep your receiver from excessive wear and tear. Keeping the hammer and trigger pins from rotating is especially important when shooting full auto or with pistol caliber builds, such as 9mm AR15's.
Standard .154" Pin Size (not for large pin Colts or M&P 22s
Comes with (2) Pins, (4) Screws, (2) wrenches & (1) guide cone
You just can't get a better set of pins for the money. They work flawlessly in my 9mm build

Quick and easy
Installed very, very quickly and all operations remained perfect. Though I'm skeptical they will prevent rotation, there is no doubt they will prevent walking. They also cover the silver line exposed on anodized 80's by the chamfer on the ends of the hammer and trigger pins.
