The Weaver 48015 Top Mount Base transforms bolt-action rifles into precision platforms ready for optics mounting. This machined aluminum base provides the solid foundation needed for consistent scope placement on Remington 541S, 541T, and Savage 19/23 rifles.
What Makes This Different
Unlike generic mounting solutions, the Weaver 48015 features rifle-specific machining that matches the exact contours of compatible receivers. The precision-fit design eliminates movement between shots that can occur with universal bases. Each base undergoes CNC machining to maintain tight tolerances, ensuring repeatable zero retention across temperature changes and heavy use.
