Re: Need help with BoMar Sight
I checked mine and it is a 6x48 and 3/8" long, thumb screw with 'indents' around the outside for good repeatable click adj. for elevation. There is also a slot for a flat screw driver.
Mine sites are flat based for my Contenders and XP-100's and use a 6x48 screws for mounting too. Not sure if that is what yours would be but the elevation screw should be the same.
The company (Bo Mar)closed it's doors but there is another one making a similar site but not sure if the screws are the same.
If you let me know where you live I'm sure there is a handgun silhouette shooter in your area that has one that I could get in touch with you.
If you need a pic I could get one tomorrow, I can't get pics onto my putor at home.
