I have gen 1 square hinge and gen 2 round hinge matching Eye Jackets. Of all the EJs I have I'm only missing the gen 1 square hinge FMJ 45mm Gunmetal. I don't have enough room or stands to display the rest of my collection but all of the EJs are there. The gen 1 FMJ 5.56 are complete too. Check out that box! It's not much but I hope you all dig it like I do.
