Qty 1 4mm rear sight retainer pin needed to pin the AK rear sight to the barrel. This 1 pin is all that is needed to secure the rear sight and this is a brand new original Military part.

    Bought three of them, All but one is 4mm one was undersized. If you only need one buy a few just in case.

    It comes a time in a builders journey when parts sometime go missing or just don't work after they were demilled. My heart dropped when it was the original broke, but AOA came in handy for a new one.
