The Weaver Standard Top Mount Aluminum Scope Base in Gloss Black—#55 Rear High Standard—is a precision optic mounting solution engineered for rifles requiring a two-piece base system. This rear base component is designed for shooters and tactical operators who demand repeatable accuracy and rock-solid scope retention. Whether you're building a duty rifle, long-range precision platform, or upgrading an existing firearm, this Weaver base delivers the durability and compatibility that law enforcement and military professionals rely on in the field.

Constructed from high-grade aluminum and finished in durable gloss black, the Weaver #55 rear base features the industry-standard Weaver dovetail profile, ensuring compatibility with a vast range of scopes and optics equipped with Weaver or Picatinny rings. The aluminum construction provides a rigid, lightweight platform that resists corrosion while maintaining tight tolerances—critical for consistent zero retention across duty cycles and environmental stress. At just 0.03 lbs, this rear base adds minimal weight to your rifle system while delivering the mechanical stability necessary for sub-MOA performance in precision applications.

This rear mount is ideal for shooters pairing it with a matching Weaver front base as part of a complete two-piece mounting solution. Installation is straightforward: secure the base to your receiver's drilled and tapped mounting holes using appropriate hardware, then attach your Weaver-compatible scope rings and optic. The #55 designation identifies this as a high-standard rear position, making it suitable for mid-power to high-power scope configurations on AR platforms, bolt-action rifles, and other firearms with standard Weaver-pattern receivers. Verify receiver compatibility and hole spacing before purchase to ensure proper fitment.
