The DuraSight Z-2 Alloy Dead-On Integral Ring/Base System – High, Black (Model: DS410B) is a monolithic, one-piece scope mount designed for direct receiver mounting on 2010-and-newer CVA break-action rifles and muzzleloaders. Built from moulded Z-2 alloy—a zinc-aluminium composite engineered to deliver steel-like rigidity at a lighter weight—this mount integrates the base and lower ring halves into a single unit to eliminate interface movement under heavy recoil. Featuring a high profile, it provides the required clearance for riflescopes with larger objective bells (such as 44 mm to 50 mm) or thick lens covers when fitted to break-action firearms.

Key Features

• Integral Monolithic Construction: Combines the mounting base and lower rings into a single structure, removing joint interfaces and base-to-ring screws that can loosen during heavy recoil.
• Moulded Z-2 Alloy: Provides precise factory ring alignment straight from the mould, clamping the optic securely without inducing uneven tube-pinching stress.
• High-Profile Clearance: Elevates the optic to ensure physical clearance between the rifle barrel, hammer, and larger 44 mm to 50 mm objective lenses or flip-open lens caps.
• Direct-to-Receiver Fit: Mounts directly to the factory-drilled receiver holes of compatible CVA break-action platforms, including Wolf, Optima, Optima Elite, Scout, and Accura/Accura V2 models.

Who is the DuraSight Z-2 Alloy High Integral Mount for?

• CVA Muzzleloader Hunters: Needs a monolithic one-piece scope mount weighing just 0.15 lb (~68 g) that resists shifting or vibrating loose when firing heavy black powder charges up to 150 grains equivalent.
• CVA Centerfire Single-Shot Rifle Hunters: Requires a high-profile mount engineered for 1-inch (25.4 mm) scope tubes to clear large 44 mm to 50 mm objective bells and rear hammer spurs on break-action platforms.

Less suitable for: Riflescopes with 30 mm, 34 mm, or 35 mm main tubes, pre-2010 CVA hole spacings, or standard Picatinny/Weaver rails; choose dedicated 30 mm/34 mm rings or Picatinny-compatible base rail systems instead.
