I have a Leupold on my cva 45-70. I think any Leupold will handle the recoil of the 45-70. I have several Leupold, I never had problem with them. I think you son will be happy with that scope.

 

I have a 3x9x40 on my Marlin 45-70 GG. I have no qualms reaching out 100+ yards with my gun...i like the extra magnification when sighting it in. Usually never need to go above 4x while hunting.

 

That is the perfect application for this scope.

 

I think he’ll be perfectly fine with that scope

 

Thanks for the replies. He ordered it today!

 

Make sure to buy quality base and rings, I like Warne steel rings and base.

 

Yep thanks. He ordered warne rings with the scope.

 

The Leupold will hold up fine on Marlin 45/70. In my experience that’s more than adequate power but I did the 20mm
on couple deer rifles and didn’t like the field of view and light gathering properties vs a scope with bigger end bell. I had whole repertoire of Ohio legal deer guns when Rifles first came in. I ended up with Leupold 2x7 on 1894 / 44mag
and Burris 3x9x40mm ?? on the 1895. I’m in SE Ohio thickets the bigger end bells extend the depth you can see into the thickets. Also better in low light conditions. Don’t have either one now, members bought them both. The 1895 rig payed off same day member bought it.

 

Absolutely!
I also use Burris scopes in the same range but Leupold get the nod for slightly better low light condition.
