I broke the bead off my SBEII. I know I know you don't need a bead and I dont look at it when I'm shooting except maybe a still target but I'd like to have it there. Its broke of in the barrel so nothing to grab to try to unscrew it. I'm not interested in any of the magnetic sights they are too big. I really would like to have something small like the factory one on there. Anybody got any ideas?
