I wanted something to clamp to the Picatinny rail on my S&W FPC.
Clamped it a little too far forward at first and zeroed then decided to clamp it a little closer to my eyes. That took all of five seconds. Rezeroed it with a couple clicks and it’s been perfect ever since.
I bought the rubber dust cover thing. It’s really nice to keep the optic clean when traveling dusty trails. More importantly, it will keep the cleaning chems off when they’re around.
Absolutely would buy again.
