Interview with C-More Inventor Ira Kay

Thanks to Brian M. for sharing this with us.

For those who shoot competitive matches, you are sure to recognize the famous C-More sight. Here is an interview with the inventor of the C-More on the Practical Shooting YouTube page.


Ira Kay was a dentist back in the 90s due to degrading eye sight he tried using reflex sights for USPSA. However they would break constantly. Like many innovators, he decided he could make something better. He made his protoypes out of dental materials. The interview explains some of the issues they saw in other sights and what features they went with to solve those problems.

    Great video, thanks.
    The open red dot sight design feels like a dramatic improvement over the tube style, for action shooting anyway.

      It may be, but C-more is not robust enough for defense

      • Nicholas C

        Where did it say the CMORE was for self defense? It is solely for competition use. Sure someone could try and use one for self defense but thats like taking a race car designed for the track to go offroad. Then complain it didnt a good job offroad. Yes you can build a race car for off road but that is not the point. The CMORE is for competition, not self defense.

        Open designs include Leupold, Trijicon, Vortex, C-More, and many others. People who have tried tubes should have a look at open ones, they are different and provide a greatly different sight picture.

        Of course it is common for different designs to have different advantages and disadvantages. Nonetheless, the popularization of open reflex designs is a nice evolutionary step for some segments of the pistol world.

        • It isn’t the open design that is the weakness. Rather, the plastic of the C-More is prone to breakage in rough handling.

      • Anonymoose

        The aluminum models are pretty good. The military bought the plastic models back in the late 90s/early 2000s and that’s how they got a bad rap.

    • Twilight sparkle

      It was an option back in 2009ish if you didn’t want to spend a lot on an aim point and they used to be the only company for a red dots on a handgun
      Fn seemed to like them, practically all fn branded red dots are from C more

      • Colt and C-More used to be in bed together back in the late 1990s. As part of the deal, Ira Kay ran the Colt Competition shop and designed several parts for the XS-series pistols. In return, Colt helped tweak Kay’s prototype C-More LSS that was ultimately adopted by the US Army as the M26 MASS.

      I liked Mr Kay talking about the M-26 and I like him in this clip, he sounds like a genuinely great guy.

  • Wild Bill

    C-More has a red dot, not the typical star burst or blurry dot of other sights. They also have diode that are multiple MOA.

  • That thumbnail image sure does look like a cutscene clip of the Evil Mastermind from a political intrigue-heavy first person shooter.

      Starring Christopher Lee.

    • noob

      plot twist! like any dentist, he only inflicts pain for the greater good!

  • A Guest

    I’m not even gonna watch the video, I want to believe that he sounds like Christopher Lee.
