I’m 66 and have astigmatism. I just got a green dot because I heard another guy with similar vision issues say that green helps. He was right. Red flares badly. Green flares much less if any. So I now have a dot that is very clear and distinct. Your experience my vary.
A green one. LOL. Holosun EPS MRS (green) for me! For EDC I run just the 32 MOA circle, no center dot, which works well out to at least 25y. For zeroing and precision shooting I'll switch to the 2 MOA dot.
I've stuck with holosun for years now. While I love both my Steiner & acro micro rds they both were greatly overpriced. I've owned multiple generation holosun optics and have had zero issues across the board over thousands upon thousands of rounds.
