Good quality red dot. enclosed is the way to go!!! - Vortex Venom Enclosed 1x Reflex Micro Red Dot Sight

I have used both reflex sights and enclosed optics and I prefer enclosed optics by far. The optic is easier to use and clean if it gets dirty, wet or muddy out in the field. I have this set up on a 45 degree offset mount on an 16'' AR 15. The optic is constructed well with a strong housing that looks like it could take a beating. It has very clear glass and a very crisp 6 MOA dot. It is very easy to rotate the rifle 45 degrees and locate the optic and the red dot and get on target and stay on target for followup shots. The optic came with plenty of different mounting screws for different mounting platforms. My only critique is I wish it came in a green dot option and/or a 32 moa circle dot. I have an astigmatism and green is easier for me to see, so the option would have been nice.
