The Husqvarna Type 33's have a rudimentary two leaffun to shoot. express sight, and an even worse front blade. Not conducive to very accurate shooting, and I was having trouble working up good loads with those sights.
I finally gave in and D&T the tang for this sight, and installed it. I think it is either 1.125" Marlin, or 1.5" Stevens? It made a huge difference in making the Husky fun to shoot.
