The Weaver Grand Slam Steel Top Mount Extension Scope Base in matte black (#S402) is purpose-built for precision rifle shooters who demand a robust, reliable optic mounting solution on their Browning BBR platform. Designed for hunters, sport shooters, and tactical professionals, this extension base solves the critical problem of inadequate clearance between standard scope mounts and barrel profiles that feature high front sights or aggressive geometry.
By extending the mounting surface forward, this base ensures proper eye relief, eliminates obstruction from rifle features, and maintains zero stability across extended shooting sessions—essential for consistent accuracy downrange. Manufactured from hardened steel with a professional matte black finish, the Weaver Grand Slam extension base resists glare and corrosion while maintaining a low-profile aesthetic compatible with tactical and hunting configurations.
The solid steel construction distributes recoil forces evenly across the Browning BBR's receiver, preventing micro-movement that degrades accuracy. Weighing only 0.2 lbs, this compact extension adds negligible weight while providing the critical forward extension needed to clear obstructions. The precision-machined contact surfaces engage securely with both the rifle receiver and scope rings, ensuring your zero holds shot after shot in field conditions.
