This pin is a common wear and replacement item on any AR-15 or M16 system as well as the HK416. Not needed on the MR556 models. This is the newer style pin that is goldish in color, super hardened and much less prone to wear and tear. The enhanced version is the most robust easiest to use pin on the plane.
