The DuraSight 0 MOA Two-Piece Scope Base (model DS113B) provides a lightweight, rigid mounting interface specifically engineered for CVA Cascade and Savage 110 (round rear receiver) bolt-action rifles. Constructed from high-strength Z2 alloy with a matte black finish, this two-piece system features standard cross-slot bases compatible with both Weaver and Picatinny-style scope rings. By utilising a split two-piece profile rather than a full-length bridge, it leaves the rifle's ejection port completely unobstructed for seamless cartridge top-loading, single-feed operations, and clear shell extraction across standard and magnum calibres.

Key Features

• Unobstructed Port Access: The two-piece receiver layout maintains clear access above the action for rapid manual loading and reliable brass ejection.
• Dual-Interface Cross Slots: Engineered to accept both Weaver-style and Picatinny-style optic rings.
• True Zero Cant: Built with 0 MOA elevation to retain full internal optic adjustment range for typical hunting zeroes.
• Durable Alloy Construction: Formed from proprietary Z2 alloy to resist standard centrefire and magnum recoil impulse while minimising added firearm weight.

Who is the DuraSight 0 MOA Two-Piece Base for CVA Cascade for?

• CVA Cascade bolt-action rifle hunters — Requires a lightweight two-piece scope base engineered to secure optics with a 0 MOA cant while fastening precisely to factory receiver threads at up to 25 inch-pounds of torque without blocking top-loading access.
• Savage 110 round rear receiver rifle shooters — Needs a dedicated split two-piece scope base system that matches factory round receiver geometry with a 0 MOA profile to preserve optical elevation adjustments for short-to-medium range hunting.

Less suitable for: Extended long-range shooting past 600 metres to 1,000 metres or shooters using optics with ultra-short main tubes; these configurations require a continuous one-piece 20 MOA Picatinny rail to provide forward eye-relief adjustment and preserve internal elevation travel.
