Weaver #20a Ia Mark X Rem 14/141

The Weaver #20a IA Mark X Rem 14/141 is a precision-engineered aluminum scope base designed for Remington 700 series rifles and compatible platforms. Built to exacting tolerances, this mounting base delivers the rigid interface necessary for consistent accuracy in both hunting and precision shooting applications where scope stability directly impacts shot placement.

Weaver bases are machined to tight tolerances that ensure a custom fit to your rifle's receiver. The aluminum construction provides maximum strength while remaining lightweight, allowing scope rings to clamp down securely without movement or play. This rigid clamping force is essential for maintaining zero across extended shooting sessions, whether on the bench at a competition or in field conditions where temperature and recoil can loosen inferior bases. The compact 1 x 0.5 x 1 inch profile minimizes profile while maintaining full clamping surface area.

This base suits shooters who demand repeatable accuracy across diverse conditions—hunters sighting in before season, precision rifle competitors, and tactical shooters who cannot tolerate zero shift. The Weaver #20a is purpose-built for Rem 14/141 dovetail receiver cuts, ensuring compatibility without gaps or shimming requirements that can introduce unwanted stress and movement.

Weaver mounting solutions remain the industry standard for precision rifles because they prioritize mechanical consistency over cost reduction. A quality base is the foundation upon which all other optics performance rests; this Weaver base delivers that foundation for the Remington 700 platform at a practical price point.
