I have two of 'em. One on my .243 Encore ProHunter barrel that does a great job, and the other on my Savage in 6.5x55 Swede. Clear picture and they both hold the zero.

My only complaint is the adjustments don't "click", and when you are sighting 'em in, you can move the adjustment slightly, and the crosshair won't move. Then you will move it slightly again.....and you will get BIG movement.

But, once you get it on......it stays there. (Unless you drop it on a thick piece of ice during deer season and have to re-sight it in. Hey.....don't ask me how I know this. I only dropped it like.....4 feet. Well, maybe it was 4.5 feet. OK...it was 5 feet!!!! Happy now!!!) Yeah.....it wasn't loaded. I was getting it out of the truck. I hate when that happens.
