DISCOVERYOPT 30mm Cantilever Scope Mount 20 MOA One-Piece CNC Aluminum, 1.6" Height

This precision-machined cantilever scope mount is built to give you a stable, repeatable platform for riflescopes. Made from a single piece of CNC-machined aluminum and finished with a hard-anodized, scratch- and weather-resistant surface, the mount resists recoil-induced movement and preserves your zero. It works on standard Picatinny rails and accepts both 30mm and 34mm tube diameters, making it a versatile choice for hunting, target, or tactical setups.

How does the cantilever design improve scope positioning?

The cantilever ring moves the scope’s centerline forward so you can maximize eye relief and clear iron sights or backup optics. The forward offset also helps mount scopes with larger objective lenses without interference from the rifle’s receiver or rail.

• 1.6" (40.6 mm) tube center height from base for optimal cheek weld
• Forward offset creates usable eye relief and space for objective bell
• One-piece design eliminates separate base-to-ring alignment errors

Will this mount hold zero under heavy recoil?

Yes — the mount is a single-piece, precision-concentric clamp designed to resist movement under recoil. Tightening specs and robust construction ensure the scope remains secure and consistently aligned shot to shot.

• One-piece CNC-machined aluminum for improved strength and concentricity
• Recommended torque: base clamp screws 30 in/lbs, ring screws 20 in/lbs
• Hard-anodized finish adds abrasion and weather resistance

Is it compatible with my rifle and scope?

The mount fits any standard Picatinny rail and accepts both 30mm and 34mm scope tubes, so it covers most modern rifles and optic sizes. The 20 MOA incline is ideal for extended-range shooting where extra elevation is required.

• Picatinny rail compatible for widespread platform fitment
• Supports 30mm and 34mm tube diameters for versatility
• Integrated 20 MOA cant for long-range elevation adjustment

What are the installation and maintenance expectations?

Installation is straightforward with basic tools and adherence to the recommended torque settings. The hard-anodized coating reduces corrosion and wear, but periodic inspection and proper torque rechecks after initial shooting are advised for peak performance.

• Use torque wrench: base clamp screws 30 in/lbs, ring screws 20 in/lbs
• Inspect fasteners after initial firing and periodically thereafter
• Wipe down finish to remove moisture and grit to preserve anodizing

Who is this for: The DISCOVERYOPT 30mm Cantilever Scope Mount is aimed at shooters who need a rugged, precision mount for medium- to long-range optics — including hunters, competitive shooters, and tactical operators. It suits rifles with Picatinny rails that require forward scope positioning, and it works well for users who value a single-piece, repeatable platform that resists recoil and environmental wear.
