Leupold 187343 Backcntry C/S Rem 700 La 20Moa
$39.59
The Leupold BackCountry cross-slot base for Remington 700 Long Action is built for hunters and precision shooters who demand lightweight, bombproof scope mounts without compromise. Machined from 7075-T6 aluminum, this single-piece base weighs just 1.8 ounces—ideal if you're counting grams on a backcountry hunt or competition rifle. The cross-slot design accepts both Picatinny and Weaver-style rings, giving you flexibility to pair it with whatever optics setup you already own or plan to add down the road.
This base comes with two sets of mounting screws (8-40 and 6-48) to ensure proper fit on your Rem 700 LA receiver. The 20 MOA cant is integrated into the base itself, eliminating the need for a separate canted ring or shim system—a clean, repeatable solution for long-range hunting and target work where elevation adjustment range matters. Leupold rates the receiver screw torque at 22 in-lbs, a spec worth noting if you're doing your own installation.
Whether you're glassing from a ridge at 10,000 feet or dialing steel at the range, a rock-solid, lightweight scope mount is the foundation of accuracy. The BackCountry base delivers the ruggedness Leupold is known for in a package light enough to leave more weight budget for rifle, ammunition, or gear that moves you to the game.

Frequently Asked Questions
Will this base fit my Remington 700?
Yes—this base is designed specifically for Remington 700 Long Action receivers. It comes with both 8-40 and 6-48 screw sets to ensure proper fit on your rifle.
What rings can I use with this base?
The cross-slot design accepts both Picatinny-style and Weaver-style rings, so you have flexibility to use most standard rifle scope rings on the market.
What does the 20 MOA cant mean?
The 20 MOA cant is a 20-minute-of-angle pre-angle built into the base itself. This gives your scope extra elevation adjustment range, which is valuable for long-range hunting or target shooting where you need to dial up significantly to reach distant targets.
What fasteners and tools do I need to install this?
The base comes with two sets of receiver screws (8-40 and 6-48). Installation requires an appropriate screwdriver and should be torqued to 22 in-lbs on the receiver screws. Use a torque wrench to ensure proper tightness without over-tightening.
