Why aren’t there options for basic red dot sights that use fiber optics other than Trijicon? I am a big fan of Trijicon and have owned several of their products including ACOG/Accupoint. I would love to have some form of Trijicon optic on every gun I own but that’s not feasible for me due to the cost. But why are there no other companies that are using fiber optic as the source of lighting for the dot? I know tritium is another element that is necessary for low lighting and is expensive too, but surely batteries could be the alternative for that as well. I’m fully aware that Aimpoints and such have battery life that will last years and years, but I’m still not a fan of battery powered dots. I know there are knock offs and fake ACOGs too, I have one on a 22 that works quite well actually, but I’m surprised companies like Vortex, Sig, Leupold, etc haven’t made some form of fiber optic/battery hybrid red dot or even tritium to straight up compete with Trijicon. Is there a patent that’s preventing this? Are the optics companies tied in closely with battery companies and there’s more money to be made by being able to keep selling batteries?
