This is one sight to walk away from!
I bought one and installed it on a Beretta Neos and took it to the range to sight it in after 75 rounds the sight adjustment quit. I could not make any adjustments. I sent the sight back to the manuficture and they sent me a replacement.
I installed the new sight and finally got it zeroed the adjustments are crude with 1/3 moa clicks.
I took the gun out to the range today and the first 10 rounds went into a perfect shot gun pasttern all over the target. The next 10 rounds were the same. I removed the dot sight and was able to maintain 3 inch groups with the iron sights.
