The Leupold Ruger Rifle Scope Mount Rings has a ring height of .73" (low), .9" (medium), and 1.03" (high).
The correct height rings to mount a 3-9x50mm scope on a Ruger No. 1 rifle using the Leupold Ruger Rifle Scope Mount Rings would depend on the diameter of your objective lens housing. Without that information I recommend using the high 30mm Leupold Ruger Rifle Scope Mount Rings in order to ensure enough clearance with your scope. These Leupold Ruger Rifle Scope Mount Rings are model 51039.
I do not believe these Leupold Ruger Rifle Scope Mount Rings will fit a Ruger 99-44 Deerfield, and I am not sure we have rings that will mount to that gun. Please email us at techsales@opticsplanet.com for more information.
Yes, they would be compatible.
No, they do not. These fit the Ruger proprietary mount.
These are a medium set of rings:
Code:LU-RR-RING-RUG-50217
MPN:50217
UPC:030317502171
Any of these sets of rings should fit your setup.
MPN:49953
MPN:49951
MPN:49952
The MPN:51041 should fit that setup.
Yes medium height ring will give you enough clearance for that scope of 1.5-6-42.
No these will not since they only cover 1" and 30mm tube.
