Thanks to the wisdom of Aldeer my daughter has bought her husband a Ruger American 30-06 for his birthday.I am going to contribute a Nikon Buckmaster scope I have in the safe and pay for base/rings and mounting. What ought I buy.

Leopold and Talley make good stuff

Talley lightweights. Combo ring and base.

From their info -

for Alloy lightweight scope mounts -

Low Mounts for 1 inch scope tube with scopes up to a 40mm objective.... for 30mm scope tube - for scopes up to a 44mm objective lens with a sporter-weight barrel

Medium Mounts 30mm scope tube - for scopes up to a 50mm objective lens if your rifle has a sporter-weight barrel.

High Mounts 1 inch scope tube for scopes up to a 50mm objective lens if your rifle has a sporter-weight barrel. 30mm scope tube for scopes up to a 56mm objective lens if your rifle has a sporter-weight barrel

Extra-High Mounts 1 inch scope tube for scopes up to a 56mm objective lens if your rifle has a sporter-weight barrel. 30mm scope tube for scopes up to a 56mm objective lens if your rifle has a has a heavier contoured barrel

Another vote for Talley lightweights.

Talley light weights

I also vote for Talley light weights. Unless they plan to use the bases that came on the rifle. At that point I'd go with Leupold PRW

I had that same rifle, and sold it. Wish I hadn't. That thing would stack 165gr Hornady ammo

Thanks guys.Talley light weights it will be
