I just installed a Lyman receiver sight on my model 36 Marlin 30-30. It looks like I need about a .600" tall sight (bottom of dovetail to top of bead) where the original sight is about .450". Some googling shows Williams front sights at one of the big box stores that aren't tall enough, and not much else. I just want a simple steel sight brass bead is fine but not interested in any kind of glow bead or gizmo. Any ideas?
