Sword Acu Site 3rd Plane with the camo 2" pin guard (large pin guard). I love this site.....perfect for hunting and it fits a large peep perfectly. Their Micro 3rd plane is the one with the small pin guard and retaining bezel thingie to add a lense and that is what I use on my 3D rig and the one I won the NYS ASA championship with. Great sites at a great price. Yes, got your email and forgot about it......responding now.
