Hawke 50 mm Extension Ring – 1″ 2-Piece High Mount (9-11 mm)

A robust and precision-machined two-piece high extension mount designed to elevate your 1″ riflescope on a 9–11 mm dovetail or Picatinny-style rail. This 50 mm extension ring provides extra forward reach and height — ideal when mounting scopes with large objective lenses or when you need just a bit more clearance for optimal eye alignment and performance.

Key Features

• High extension configuration: Adds 50 mm (≈2″) of forward height between your rail and scope tube to improve clearance and positioning for larger optics.

• Two-piece design: Allows flexible alignment and easier installation, as well as compatibility with a variety of rifles and rail setups.

• Compatibility with 9-11 mm rails: Works with common 9–11 mm dovetail mounts and, in many cases, also fits 3/8″ dovetail rails with a reversible clamp.

• Secure clamping: Double hex screws firmly secure both the rings and the scope tube to prevent movement under recoil or heavy use.

• Internal cushioning: Soft tape inside the rings protects your scope tube from scratches and marks while also helping prevent slipping.

• Durable aluminum build: Lightweight but strong anodized matte black aluminum construction enhances durability while minimizing added weight.

• Rounded edges: Precisely finished edges help avoid tool and scope damage during installation and handling.

Technical Specifications

Design & Usage

This 50 mm extension ring mount is engineered to lift and shift your riflescope forward and upward — especially useful when mounting larger objective scopes, long eye-relief optics, or when you need extra space between the barrel and scope body. The two-piece design allows for more precise positioning compared to one-piece mounts, giving you the flexibility to tailor the placement to your firearm and shooting style.

The internal cushion tape and robust clamping hardware help protect your scope while ensuring it stays secure under recoil or extended use. A recoil stop pin on many 9–11 mm versions provides additional resistance against forward creep over time.

Ideal for:
✔ Scopes with large objective lenses that require extra rail clearance
✔ Rifles with low-mount rails or limited clearance
✔ Situations where forward placement aids eye relief or shooter ergonomics

Installation Tips

1. Confirm compatibility: Ensure your firearm’s rail measures between 9–11 mm in width before installation.

2. Level the rings: Mount and loosely tighten the base rings first, then place your scope and adjust for a level sight picture before full tightening.

3. Torque appropriately: Use correct torque for the hex screws to ensure a secure mount without overtightening and damaging the scope tube.

4. Check eye relief: After installation, verify that your eye relief is comfortable for your shooting stance.
