Really solid unit - SightMark Wolverine 1x28mm FSR Reflex Red Dot Sight

I bought this red dot after reading several reviews and watching a couple of video reviews on it. It certainly didn't disappoint. It holds zero nicely and the different brightness settings make it easy to use in the day or night. Can't beat the battery life either. I'm relieved to finally be able to use a regular AA battery instead of having to look online to order those button batteries. But with something like 60,000 hours of life on a single battery, I don't think I'll need to replace this one any time soon. Only thing to watch out for is make sure you tighten the nut when you install. I thought I had, but there was still some give and the sight shifted. I re-centered it, tightened the lug nut down, and she's good to go.
