Good value for the money - TruGlo True-Brite Open Red-Dot Sight TG8380B

I've had this for 3 - 4 months now, and have used it in about that many metal mania matches at my local club. I was using an Eotech 512 holographic sight on my Ruger 10-22, but as the days became brighter it just couldn't keep up (BTW, this is the second Eotech 512 I've had that just faded away in bright sunlight. Probably won't be a third one...) The Tru-Brite red dot sight has easily withstood the punishing recoil of almost 500 .22 LR rounds :), and I think it would work just as well on an AR. You can select red or green reticles, which is nice, I guess, but not hardly necessary. Brightness to spare, and the reticle is crisp. Haven't had to replace the battery yet, but it's easily accessible without removing the sight. Longevity not as good as some other red dot sights, but certainly adequate and if you use an electronic sight you should be religious about having a spare battery around anyway. Reader's Digest version: I'm happy with the sight and would recommend it.
