Holosun he 507k green-dot - Holosun HE507K-GR X2 1x Green Dot Reflex Sight

I purchased this Holosun HE 507K Green-dot and mounted it on my S&W M&P Sport II AR…5.56. I have an stigmatism and the green version (instead of the red) looks much better to me. Also, I can discern patterns with the green light much better than red in bright sunlight as well as in the evening. …. I also purchased a Vortex Razor red-dot holographic Gen II UH-1 sight for $623 and I sent it back in favor of this sight. The viewing widow is actually larger in this sight vs the holographic one and it’s lighter. It also has the convenient solar panels………..Unless you are concerned with heavy rain or dirt being thrown around and filling in your sight , no need to go with the twice as expensive holographic sight IMO. I also like the three reticle targeting options….2 MOA dot…32 MOA circle …or the combo of both is very nice. The green 32 MOA circle actually sets absolutely perfectly within the space of the front fixed sights of my Sport II AR-15. VERY happy with this green-dot 507K Holosun and I highly recommend it for your AR rifles for short to medium range weapons.
