Have a M1911 with the excellent fixed Novak rear sight that really wish you could have a BoMar on instead? You aren’t the only one. But, as you have likely already learned, the slide dovetail cut for one just will not allow the use for the other. Good news though. .
Karl Beining custom gunsmthing extraordinaire and Brandon Bunker has come up with a very slick solution
The Nomar sight base is the solution for the large numbers of 1911s being sold with Novak Low Mount fixed rear sights. Many Colts, Springfields, Rugers, Dan Wessons, Rock Island’s etc come right from the Factory with a Novak Low mount rear sight cut. This is a fantastic sight cut if you want fixed sights, but the adjustable options that fit the Novak LM dovetail are all lacking. Some have very limited adjustment, some have no windage adjustment at all, but they all have small sight faces resulting in less than ideal sight picture for precision work. The Gold Standard for 1911 Target sights is, and has been for decades, the Bomar Adjustable sight, the issue is once a slide is cut for a Novak LM rear, you cannot cut it for a Bomar cut, so a workaround had to be designed. I teamed up with Brandan Bunker at Bunker Arms on designing a new base for the Bomar style blade (Mfg By Kensight), and the Nomar was the result. We worked through a couple tests and redesigns to arrive at the current iteration that we feel looks the best and will work with the widest breadth of OEM Novak cuts. Believe it or not, not every company cuts Novak rear cuts the same, so we are looking at making a taller base for STI slides and possibly others in the future. The Nomar is not a wholly new idea, Rich Dettlehouser of Canyon Creek made some similar bases nearly 10 years ago, but seems his website and access to this part are gone.
The Nomar base does require professional installation as the Novak sight deck will need lowered and extended forward of the dovetail, pocket for the sight blade cut, and hole drilled and tapped for the elevation screw.
I’ve been watching this project and the pictures Karl has shared on various 1911 groups he and I both belong to. They look great and the work is first class. If you have a 1911 with a Novak cut but wish you had a BoMar you now know what to do.
