Excellent reflex sight - Holosun HE510C Elite 1x 2MOA Reflex Green Dot Sight

I mounted this on a Mossberg 930 and it’s worked great. I had another brand’s reflex sight on it, and after 10 rounds, the zero drifted and wouldn’t move horizontally, no matter how many clicks I adjusted. But, I’ve put 20 rounds thru it (all buckshot) with the 510C and it’s maintained zero perfectly. The green reticle is much easier for target acquisition, both day and night. Good FOV and the reticle adjusts for practical use from bright daylight to night. The lower profile and light weight makes it an ideal addition. The shake to wake and solar cell capabilities top off an already excellent sight.
