|This sight works well on my Ruger MKIII Hunter. Dot size is small and nicely suited for plinking and hunting. Usually, I use brightness settings 6-10 during the day with polarized sunglasses on, and setting 1 indoors. No visible halo or fuzziness on the proper setting.
This sight came with extremely ugly weaver rings, see through covers, an extension tube, and a battery. The rings seem sturdy, but the allen screws included look questionable. The covers are nice, and work with and without the extension tube. Personally, I think the scope looks goofy without the extension tube.
So far, it has held its initial zero through about 2000 .22 Long Rifle cartridges (and many a rough Ruger disassembly!) using the included rings and screws.
This is a great sight, at a great price. It would receive 5 bullets if it wasn't so eerily plain looking, included respectable rings and hardware, and had a slightly lower setting 1, only minor complaints though. I'm planning to buy the 25mm SP1 for comparison; it supposedly, has an even smaller dot.|
