Not perfect, but really close - Meprolight M22 Rifle Sight

If you're in a darkened room looking out, where the tritium isn't bright enough, and the fiber optics are getting no light, the reticule will wash out. That's the nature of the beast, and that's a rare thing. Maybe 5% of the time. Moving a couple if feet will fix it. The sunshade is a must for that reason. I am still going to buy the LED light kit so I have the option to have an electronic dot ( triangle �️ ). It will be the perfect end of the world sight once that's done. 95% there as it is. If the stuff hits the fan, I'll have what I need for any condition. When my battery supply is gone, I'll have what I need for 95% of conditions. The retcule is very bright and and clear in most instances without the battery.
