Hawke Sport Optics 1-Piece MOA Weaver

A precision-built single-piece compensating base from Hawke Sport Optics engineered to mount optics securely on rifles with 9–11 mm dovetail or Weaver-style rails. This adjustable base helps you fine-tune elevation for long-range optics while maintaining proper alignment of your scope rings, making it easier to achieve clear sighting and optical centering beyond turret travel.

Note: This model has been discontinued by the manufacturer, but the core design and features still reflect how it works and what it’s intended for.

Key Features

• Adjustable MOA Compensation: Built-in adjustment dial raises or lowers the height of the ring mount to add MOA of elevation for long-distance shooting or to recover lost turret travel.

• One-Piece Design: A single robust piece provides alignment stability and a secure attachment for both rings — reducing the risk of misalignment between tube rings.

• Weaver/Dovetail Compatibility: Designed for use on classic Weaver or 9–11 mm dovetail rifle rails, allowing flexible mounting across many platforms.

• Matte Black Finish: Provides a non-reflective surface ideal for hunting and tactical use.

• Maintains Scope Zero: Adjustments are made while maintaining the relative position of both rings, helping preserve your optic’s zero.

Technical Specifications

Performance & Application

The Hawke Sport Optics MOA Weaver Compensating Base was designed to assist shooters who need extra elevation adjustment beyond standard scope turret travel — especially helpful with high-power optics, long range shooting, or when mounting optics on rifles with limited turret range. The compensated base lets you dial in the correct angle by elevating the front sight base while keeping ring alignment constant, giving more room for fine-tuning adjustments downrange.

This compensating base is especially useful when:
✔ You need additional elevation for long-distance ballistics
✔ Turret travel on your scope isn’t sufficient for your target range
✔ You’re using optics with large objective lenses that require extra clearance
✔ You want consistent ring alignment with a secure one-piece design

Installation Tips

1. Confirm Rail Width: Ensure your rifle’s rail is a Weaver or 9–11 mm dovetail before attempting installation.

2. Level Before Tightening: After mounting the base, lightly snug the fasteners, check that it’s level, then fully tighten in stages for even pressure.

3. Adjust in Small Increments: Use the MOA adjustment dial gradually to find the desired elevation setting.

4. Zero After Mounting: Once installed and adjusted, re-verify zero at the range as a best practice to ensure accuracy.
