Swiss Schmidt-Rubin Straight-Pull Rifle Database

The MSM-02 is a fixed cantilever scope mount specifically engineered for AR-10 and AR-15 platforms. It features a lightweight yet exceptionally rigid cantilever design that ensures maximum comfort and optimal eye relief during fast-paced, dynamic shooting, while providing superior structural integrity required for the heavy recoil of AR-10 rifles.

Platform Compatibility:
AR-15
AR-10 / SR-25
Bolt action rifles up to .308 Win

Benefits:
Optimized Mounting Geometry: Achieves perfect, repeatable positioning on the Picatinny rail with zero shift under fire.
Precision Center Recess: The bottom mounting surface features a precision-milled longitudinal center recess. This ensures contact with the Picatinny rail occurs along two narrow parallel lines, minimizing the impact of rail imperfections and ensuring consistent re-zeroing after detachment.
Milled Recoil Lug: The recoil lug features a center-cut design that limits the contact area within the Picatinny slot. By distributing clamping force over two narrow bearing surfaces, it neutralizes rail tolerance issues for ultra-stable positioning.

Features:
Cantilever Design: Features an extended forward offset that allows the optic to be positioned further forward. This geometry ensures the mount remains exclusively on the upper receiver - the most rigid part of the AR platform-preventing "bridging" onto the handguard, which lacks the necessary rigidity for stable mounting.
Optimal Eye Relief: The forward shift optimizes the distance between the objective lens and the shooter's eye, significantly improving ergonomics and target acquisition speed.
Internal Ring Grooves: The inner surface of the rings features precision-milled grooves that create localized high-grip zones when tightened. This design eliminates the risk of micro-slippage during heavy recoil.
Integrated SMAI Interface: Built-in SMAI-A ports allow for extensive customization, enabling shooters to attach various accessories to enhance their operational experience.
Triangular Geometry: The SMAI interface is based on the triangle—the strongest and most stable geometric form in engineering—ensuring a secure hold even for heavy accessories.
Drainage Channels: All structural openings are designed with drainage to ensure proper circulation of chemical solutions during the anodizing process. This guarantees a uniform, high-quality coating in all internal areas and threads.
Premium Material: Manufactured from 7075-T6 aircraft-grade aluminum, the strongest aluminum alloy in the world.
Superior Finish: Hard Anodized finish for maximum durability.
High-End Fasteners: Equipped with high-quality stainless-steel screws featuring a durable dark anti-reflective coating.
