The Sportsmatch Weaver 1 Piece 30mm QD Med Triple Screw (Model OP91) is a precision-engineered, high-stability optic mounting system designed and manufactured in the United Kingdom. This premium one-piece mount is engineered to secure modern 30mm tube day scopes, thermal optics, and night vision units to standard 20mm wide Weaver and Picatinny receiver rails. Designed to withstand heavy recoil, the OP91 provides shooters with a highly secure platform that maintains a repeatable return-to-zero, making it a reliable choice for demanding field environments.

Key Features:

• Triple Screw Clamping: Each ring utilizes six heavy-duty screws (three on each side) to provide maximum clamping pressure, preventing scope slippage even under heavy recoil.
• Dual Fixing Mechanism: Equipped with 20mm indexable quick-detachable (QD) levers for fast, tool-free optic swaps. It also includes standard heavy-duty fixing nuts for users who prefer a permanent, bolt-on installation.
• Integrated Spirit Level: Features an anti-cant bubble level built directly into the rear of the base, allowing shooters to quickly verify alignment and maintain consistency at long distances.
• Rigid One-Piece Design: Machined to exacting tolerances to deliver superior structural alignment compared to traditional two-piece ring sets.

Who It Is For:

The Sportsmatch OP91 is designed for Australian hunters, target shooters, and tactical competitors who require absolute structural integrity from their aiming systems. It is particularly well-suited for regional Australian hunters who regularly switch between daytime optics and thermal or night vision devices on the same rifle. The 15mm medium height profile is ideal for standard bolt-action and centrefire rifles, allowing a low-to-bore optical axis while easily clearing 50mm objective lenses for comfortable cheek weld and consistent eye alignment.
