BKL-257H 0.6″ Long High Dovetail Rings – Scope Mounting Rings

The BKL-257H 0.6″ Long High Dovetail Rings are robust, high-mount scope rings designed to secure a 1″ (30 mm) scope tube on rifles equipped with standard dovetail rails (3/8″ or 11 mm) — common on airguns and rimfire rifles. These rings are taller than the standard model to provide additional clearance for larger or objective-heavy optics, helping ensure proper eye relief and unobstructed view.

Key Features

Designed for 1″ Scope Tubes:
• Specifically sized to hold 1″ (25.4 mm) diameter riflescope tubes, making them compatible with many popular optics.

High Mount Height:
• Taller than the standard BKL-257 rings, these “high” rings position the scope farther above the rifles’ bore line. This extra height helps clear large objective lenses or front sights that might otherwise interfere with the line of sight.

Clamping Length & Fit:
• Both the overall length and clamp length measure approximately 0.60″, providing a stable base across the dovetail. The ring width is also roughly 0.60″, suitable for reliable attachment.

Sturdy Construction:
• Built from high-performance aluminium with a matte-black finish for durability and a sleek look that complements most rifles.

Dovetail Compatibility:
• Designed to work with standard riflescope dovetail rails found on many air rifles and rimfire firearms — making installation straightforward and secure.

Independent Rings:
• Sold as a pair of individual rings, which allows flexible spacing to match your rifle’s dovetail length and scope position preferences — ideal for tuning eye relief.

Performance & Practical Use

The BKL-257H high dovetail rings offer a solid and reliable mount for optical scopes on rifles with dovetail rails. Their higher profile is especially useful when the scope’s objective lens or rifle features (like sights or barrel shrouds) would interfere with lower mount options. This ensures your optic sits high enough for a full field of view and comfortable eye relief.

Made from machined aluminium, the rings balance lightweight construction with strength, helping keep your setup stable even under repeated recoil. Because these rings are independent (two separate rings), you can adjust spacing for optimal positioning and balance on your rifle’s dovetail rail — a useful benefit when fine-tuning scope placement.

Best Suited For:

✔ Air rifles and rimfire rifles with standard dovetail rails
✔ Shooters mounting optics with larger objective lenses
✔ Situations where extra height and clearance are needed
✔ Users who prefer independent rings for scope positioning adjustment

User Tips

Confirm Scope Tube Size:
Before installing, ensure your scope uses a 1″ tube — these rings won’t fit larger (e.g., 30 mm) tubes without adapters.

Set Eye Relief First:
Install one ring and roughly position the scope, then slide the second ring into position before tightening — this ensures the best eye relief and comfort.

Tighten Evenly:
Use consistent torque on all screws to keep the rings aligned and avoid pinching the scope tube unevenly.
