Weaver 48473 Top Mount Base Pairs Matte Black Mossberg 500/835

The Weaver 48473 Top Mount Base Pairs provide a rock-solid foundation for mounting optics on Mossberg 500 and 835 shotguns. These precision-machined aluminum bases replace the factory receiver with a durable mounting platform that maintains zero through thousands of rounds.

What Makes This Different

Unlike flimsy saddle mounts that clamp over the receiver, these bases integrate directly into the shotgun's action for maximum rigidity. The two-piece design distributes mounting stress evenly across the receiver, preventing flex that can throw off point of impact. Each base features multiple cross-slots machined to exact Weaver specifications, ensuring compatibility with virtually any ring or mount system.

Key Features

• Precision-machined 6061-T6 aluminum construction for lightweight durability
• Matte black anodized finish resists corrosion and eliminates glare
• Direct receiver integration eliminates mounting flex and maintains zero
• Standard Weaver cross-slot pattern fits all compatible rings and mounts
• Two-piece design distributes stress evenly across receiver rails
• Compatible with Mossberg 500, 590, 835, and Maverick 88 shotguns

These bases excel in demanding applications where shot placement matters. Turkey hunters appreciate the rock-steady platform for precise slug placement at extended ranges. Law enforcement agencies rely on the zero-retention capabilities during patrol vehicle transport and tactical deployments. The low-profile design maintains the shotgun's handling characteristics while providing a stable optics platform that won't shift under recoil.
