patterson0108 Posted July 21, 2009 Share Posted July 21, 2009 Just wondering if anyone knew the thread pattern of the front fiber optic sight on a SBE II. I am looking at changing to a bigger truglo front sight. Also, how hard is it to unscrew the factory front sight. I was told that I would have to apply some heat before it would come loose.

agm65ccip Posted July 21, 2009 Share Posted July 21, 2009 Supposedly its 3-56. When I took off the front sight I didnt use any heat, you might want to. But all I did was take some needle nose pliers get as much surface contact as possible and gently and gradually increase pressure until the locktite broke and then it was out, and the new sight went in very easily.

patterson0108 Posted July 21, 2009 Author Share Posted July 21, 2009 I think truglo references the thread as 2.6mm, but when I contacted benelli the tech told me she thought it was 2.5mm on the SBE II. Then just as you, a few post on here reference it as 3-56. Quote Link to comment Share on other sites More sharing options...
agm65ccip Posted July 21, 2009 Share Posted July 21, 2009 well if that is what benelli said I would go with that, I'll admit that I wasn't as concerned with the actual thread size when the sight I ordered came with a screw for benellis and it fit in just nice Quote Link to comment Share on other sites More sharing options...
