I think I sent a post yesterday about your sight, but I don't see it. I have a new one that is still in the little plastic bag they came in. Mine says it is a "Thompson/Center Hawken-Renegade Vernier Tang Sight" a No. 719. It also says "This sight is intended for use with Thompson Center Globe front sight No. 721". I did some measuring on my Investarm Hawken, my origional front sight is not tall enough for this sight, I had to find a taller one. I have not mounted these sights yet. Hope all goes well.
