Description
Leupold built the BackCountry series for hunters who count every ounce without wanting to give up toughness, and this set is tailored specifically to the Winchester Model 70. Rather than running a separate base and ring like a traditional setup, each piece integrates the base and ring into a single machined unit. That means fewer connection points, less stacked tolerance, and a cleaner, lower profile on the rifle. These are built for a 30mm scope tube at a high ring height, so there's room to clear larger objective bells on a hunting rig.
What Makes the BackCountry Mount Worth It
These are machined from 7075-T6 aircraft-grade aluminum, the same strong, lightweight alloy you'll find on premium mounts, and finished in a durable matte black anodizing that blends in and holds up to weather. The whole set tips the scale right around 3.4 ounces, which is a big deal when you're packing a rifle up a mountain. Folks who run these tend to compare them favorably to other popular lightweight mounts, pointing to the machining quality, fastener quality, and finish as reasons they keep going back.
Fit and Setup on the Winchester 70
This set is cut specifically for the Winchester Model 70 and attaches directly to the receiver, so there's no separate rail to add. The front base is reversible, which gives you a little extra flexibility in positioning for proper eye relief and scope length. Installation is straightforward and the hardware comes in the box. Leupold spec is 22 inch-pounds on the base and receiver screws and 28 inch-pounds on the ring top screws, so a good torque wrench is your friend here.
If you're setting up a Winchester 70 for hunting or long days in the field and want a mount that stays put, keeps weight down, and looks clean doing it, this BackCountry set is a smart match. Pair it with any 30mm scope and you've got a dependable, no-drama mounting solution.

Frequently Asked Questions
What rifle does the Leupold BackCountry 171121 set fit?
This set is cut specifically for the Winchester Model 70 and bolts directly to the receiver. Because it's rifle-specific, there's no separate rail or base to source. Just confirm your Model 70 matches the standard receiver footprint before you order.
What size scope do these BackCountry rings accept?
These rings are made for a 30mm main tube, so your scope needs a 30mm center section. They're set up at a high ring height with a 1.1 inch ring height, which gives good clearance for larger objective bells common on hunting and variable-power scopes.
Why choose an integral mount like the BackCountry over a base and separate rings?
The BackCountry combines the base and ring into one machined piece, which removes the ring-to-base connection and cuts both weight and stacked tolerances. That translates to a stronger, lower, cleaner setup that tends to hold zero well. It's a popular pick for lightweight hunting rifles where every ounce counts.
Does this set come with the mounting screws, and what torque should I use?
Yes, the necessary mounting hardware is included in the box. Leupold specs 22 inch-pounds on the base and receiver screws and 28 inch-pounds on the ring top screws. Using a torque wrench set to those values will keep everything secure without over-tightening.
