Review on Hillman Group 556 1 Inch 12 Pack: Heavy-duty Hardware Essential for All Your Projects by Ron Patel

So I had to return the first order because I literally received an empty box (yes I had to return an empty box to get my money back). The next order came with all the pins in the package, but at least the pins were there. The problem was that the pins were crap. Standard Ruger AR pins have a nice smooth 1° taper, these pins technically had a taper but were a wavy, jagged, inconsistent blend from end to end. Not sure if they can be used in a specific application.
