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 perfect update, range finder and it married, works great for hunting.. sooon on target on 200 not sure on going out full Profiles 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

Great scope for the money.
I haven't had a chance to take the scope to range yet. I was hoping to this week but it just didn't work out. Maybe next weekend. I did sync the scope with my iPhone and added my Hornady bullet for 6.5 creedmoor rifle. And I also added 200, 300, 400, 500 and 600 yard BDCs to the reticule. In other words I have a dot for each of those ranged yardages. I haven't bought the BDX rangefinder yet. Still trying to decided which one I want. I also like the built in level to tell if I am leaning a little left or right. I went with this scope just in case I ever wanted to shoot the 6.5 creedmoor out to 800 yards and beyond. Since I don't shoot that often. I doubt I could do a cold bore shot out to that distance. But I believe I could with this scope and Sig range finder. Overall, very impressed with the ease of the set up of the scope. The scope arrived sooner than expected by about 4 days. Thank you Vender!

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.

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

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.

Unbelievable value for the technology
I bought my first BDX for my Ravin R29X crossbow, I was so impressed I purchased 2 more for my rifles, my brother couldn’t believe the accuracy of these scopes and the value for what you get so he bought 3 for his rifles. I believe the prices on these scopes are to test the waters now and they may raise so it may be smart to buy what you can afford now, just my opinion.

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!

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
