I really love this red. Dot with ACSS It was becoming harder to find the red dot The new ACSS ring is awesome. I’m going to be buying two more shortly soon as I find some time. Definitely pick one up shake awake feature the battery will last way longer than you want to great purchase great place to buy from.
I have terrible vision - distance, close, astigmatism, coke-bottle lenses, no longer correctable to 20/20, very thankful I’m not completely blind. The green Vulcan (chevron) with the full circle for recapture is 1000x better than the typical red dot. I tested it on my FN 509 CC Edge, a firearm I am not loving, and suddenly I like it a lot more. I’m getting one of these for all my handguns.
Love these micro in closed sights. Shake awake is a huge selling point. Solar backup doesn’t hurt either. Features and settings are super easy to change also. I went with Green Dot because I’m starting to have vision issues and the GD is super easy to pickup regardless. Very easy to zero and these sights do hold zero well. Pro X2 has been on my shorty AR10 and now the 15. This is a good all around option with awesome battery life. Very easy to use, setup, zero, with some cool little features. We’ve been using the 510Cs and the original AEMS here long enough to say they are reliable. Can not vouch for torture tests because we handle our rifles with care. Loaded up to shoot it is a pretty rough ride up the mountain though so they take that beating well. Hope this info helps with your decision.
Only cons I can say is the Auto brightness feature doesn’t work in a MOUT scenario with attached lite source because it is in front of the rifle. You will need to remember that in low light scenarios. If you’re worried about, “parallax” stop watching internet videos and work on your fundamentals. The original AEMS with worse windows wasn’t even an issue. Choice is yours. Happy hunting.
Great price from Freedom Gorilla! Fits on my M&P 2.0 9mm perfectly while allowing a co-witness with my XS Big Dot glow sights. Best part is not having to deal with any adaptor plates.
Installation was simple. It performs as intended.
It is a great optic. I like the gold dot. I pick it up very well and can get on target quickly with it.
Freedom Gorilla ships quickly and they do a great job with customer service.
Good solid fit, works as intended. Nicely coated, screws that came with are the correct length. Very nice height with EPS and RXM sights.
