The Leupold BackCountry cross-slot base for the Remington 783 in the 6.3-inch length (part no. 175973) gives that budget bolt-action a longer mounting surface than the shorter 5.9-inch variant, useful for scopes needing more forward or rearward ring placement. Leupold machines the base from 7075-T6 aircraft-grade aluminum to minimize weight while maintaining rigid support, and it accepts both Picatinny- and Weaver-style rings for broad compatibility. The matte black finish blends with standard rifle finishes in the field. Among 783-specific scope bases, this longer 6.3-inch configuration gives more ring-placement flexibility.
