I may have the chance to make a trade for a Leupold LCO red dot sight to put on my BFR 45-70. It is actually mounted on it now, and I positively love the view. My question is does anyone know if this optic will stand up to the recoil? It was mounted on my son's AR-15. Any warnings or issues I need to be aware of? I don't want to shake loose a 600.00 optic that was designed for something a little less...vigorous.

I'm going to go out today and sight it in. Should be fine, it is a Leupold with lifetime warranty. I have finally gone exclusively hand gun, more-or-less. There is an AR in the house for other purposes, but my last hunting rifle went this week. Went bear hunting a couple of weeks ago, and it was a bust. But I'm already planning a fall hunt, and am taking the BFR. I have the rest of the summer to get the optics workable for me, along with lots of trigger time.

I am sure Leupold will stand behind it. What size dot does it have?

It has several sized dots, both red and green. I hope they do stand behind it, because it broke. The L-to-R adjustment screw was adjusted all the way to the right, with the bullet holes still 12" too far left. I went to adjust it one more click, and something broke loose inside. (sigh) I think I'll take up hunting with a sharp stick. It's cheaper, and my rate of success will still remain the same.

Usually Leupold only warrants their electronic items for 1 year. I found that out with a rangefinder. They did give me 50% off MSRP for something new though.

Sorry to hear that. Hope Leupold takes care of it.
