The Leupold BackCountry one-piece cross-slot rail with 20 MOA and a 6.3-inch length for Fieldcraft LA rifles (part no. 175648) gives a rigid, low-profile platform for precision optics on long-action rifles. Leupold machines the rail from 7075-T6 aircraft-grade aluminum, and it accepts both Picatinny and Weaver-style rings for broad compatibility. The one-piece layout preserves bore-to-optic alignment under repeated use, and the matte black finish minimizes glare. Among long-action scope bases with built-in elevation, this BackCountry 6.3-inch configuration favors extended-range hunting and precision setups.
