Review: 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
Review: 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.
*by D***D on May 21, 2021*

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.
