Excellent but switch between bore site each time
Haven used it yet weather is a bi.tch. like it and will update soon very well packed wow perfectupdate, range finder and it married, works great for hunting.. sooon on target on 200 not sure on going out fullProfiles if I change between rifles do I need to bore site after each time or does it hold in the profile once all setup. Still happy first shots on bore 2 low 2.15 right. I do wonder if I have to redo bore once setup for different long guns like from 223 308 300 334 I think it would have to re scope. Not like my atn hr

IT WORKS!
Used in combination with my KILO 2200 BDX rangefinder. I was able to zero at 100, link up with the rangefinder and make 1st round hits on torso targets at 200 and 300 without adjustment. I needed 1 click left at 300 to be on a smaller round plate(Don't know the size. First time I had shot at this shooting range. Head size compared to torso targets.) So 4 hits out of 5 on 4 targets from 1-300yds just using the BDX info and 1 click of windage on a first sight-in of a new gun. I'll take that any day!

Incredible Optics
The BDX System takes difficult shots and ensures an accurate shot. When coupled with the KILO BDX Rangefinder, takes inclination, temperature, wind, (your direction to it included) and compensates for the bullet that you have selected and the performance characteristic of each.You can create different bullet profiles and use the scope on separate rifles, which is impressive if you've got a pica tinny rail system for mounting. Great quality glass and light to ensure visibility for long shots.

Diopter inoperable
Nice scope but the diopter adjustment would not turn.

Excellent product for the money
I am so impressed by these scopes that I own 5 of them, they are truly unbelievable. However, if you purchase one, make sure you take the time to learn how to use it correctly or you will not understand it and will be frustrated. If you take the time, you will be impressed.

Great scope!
I bought this scope for my hunting rifle. Love the BDX simple to shoot! Picture 100 yard zero with BDX setup at 500 yards. Impact is 1.5" to the right

Works as advertised.
Mounted the scope and it holds zero well.The crosshairs are a bit wider so if your looking for a target scope, maybe not the best as I love the thin lines for long range shooting.But for hunting and using this scope with the BdX rangefinder, great pkg.

Great Michigan hunting scope.
Absolutely love this. I purchased 2 of these. One for my 350 and the other for my 450.Ben's in Marlette, MI installed them and they are worth the purchase.
