The CCOP Weaver to 3/8” 1-Piece Rail Base allows firearms with a 3/8” (11 mm) dovetail rail to accept Weaver-mounted optics or accessories. This adaptor provides a secure and stable mounting platform, making it ideal for upgrading rimfire rifles and airguns to support a wider range of modern Weaver-compatible mounts.

Precision-machined from aircraft-grade aluminium, the one-piece design offers excellent rigidity and consistent alignment while keeping weight to a minimum. The low-profile construction helps maintain a proper optic height, and the matte black finish reduces glare while providing long-term durability.

The CCOP rail base clamps directly onto a standard 3/8” dovetail rail, creating a solid Weaver-style rail surface suitable for scopes, red dots, and other Weaver-compatible accessories.

Key Features:

  • Converts 3/8” (11 mm) dovetail to Weaver rail

  • One-piece design for strength and stability

  • Lightweight, durable aluminium construction

  • Low-profile configuration

  • Non-reflective black finish

  • Simple, secure installation

A practical and cost-effective solution for adapting Weaver-mounted optics to firearms with a 3/8” dovetail rail.
