John, I was certain that you were younger than me. I think I'm the "old guy" here! I'll get some close-ups of the mags but it is nightfall right now so it'll wait for another day. Here's a glimpse of one of the D&H-20s in one of my ARs. What is different about them is they are curved 20s. I like 'em a lot! You can see the stampings on the side in this photo.
