Technical Specifications

Performance & Use

This Diana 25.4 mm scope mount provides a reliable platform for mounting a 1-inch optic on rifles that use an 11 mm dovetail rail. It’s particularly well suited to airguns and other rifles with spring or gas ram power systems where strong recoil and vibration can otherwise shift less-rigid mounts.

The built-in safety stop pin helps reduce unwanted forward creep of the mount under repeated recoil, and the single solid block design supports consistent zero and alignment. Whether you’re adding a new optic for hunting, target practice, or general field shooting, this mount brings a mix of strength and simplicity to your setup.

Ideal for:
✔ Air rifles and break-barrel guns with 11 mm rails
✔ Scopes with 1 inch (25.4 mm) main tubes
✔ Users seeking a rugged, reliable mounting solution

Installation Tips

1. Check Rail Size: Confirm your firearm uses an 11 mm dovetail rail before mounting.

2. Secure Positioning: Slide the mount onto the rail ensuring it seats fully before tightening fasteners.

3. Use the Stop Pin: Align the safety stop pin with a rail groove to help lock the mount in place.

4. Level the Scope: Position your scope for proper eye relief and level before final tightening.
