BKL-568 4″ Long Dovetail to Weaver/Picatinny Adapter Mount

The BKL-568 is a durable mount adapter that converts a rifle’s standard dovetail rail (3/8″ or 11 mm) into a Weaver/Picatinny-style platform — opening up your firearm to a much wider range of modern optics and accessories such as red dot sights, scopes, and tactical attachments. Its 4″ length and cantilever-style layout provide extra forward space for optical eye relief and accessory positioning.

Key Features

Dovetail to Weaver/Picatinny Conversion:
• Securely adapts a 3/8″ or 11 mm dovetail rail into a Weaver/Picatinny rail, letting you fit accessories that require the more common rail standard without replacing the entire base.

Extended 4″ Adapter:
• The 4-inch length gives you extra clamping space and forward room, ideal for optics that need additional eye relief or positioning flexibility.

Robust Construction:
• Made from aircraft-grade aluminium with a matte black finish, this adapter is both lightweight and tough enough for regular field use.
• A multi-screw clamp design delivers a stable, centered mount that holds accessories securely even under recoil.

Expanded Accessory Options:
• Perfect for mounting red dot sights, scopes with Picatinny rings, and other rail-mounted accessories that wouldn’t fit directly on dovetail rails.

Performance & Practical Use

The BKL-568 adapter is a versatile solution for shooters who want to use modern rack-and-pinion optics and accessories on firearms originally equipped with narrow dovetail rails — common on many airguns, rimfire rifles, and vintage platforms. By adding a long Picatinny-style rail, it gives you plenty of room to install optics at the correct eye relief and customize your setup for comfort and performance.

The adapter’s broad clamping surface and multiple screws help ensure the mount stays firmly in place, reducing the chance of movement under recoil — a particularly common challenge on dovetail rails. Using this adapter effectively opens up a wider range of accessory options, from red dot sights for quick target acquisition to full-featured optics for precision shooting.

Best Suited For:

✔ Airguns and rimfire rifles with standard dovetail rails
✔ Shooters wanting to use Weaver/Picatinny optics
✔ Red dot and tactical sight installations
✔ Configurations requiring more forward rail placement for eye relief

User Tips

Confirm Rail Compatibility:
Measure your rifle’s dovetail rail width (3/8″ vs. 11 mm) to ensure the BKL-568 will fit before installation.

Secure Installation:
Align the adapter carefully on the dovetail and tighten screws evenly to prevent skewing; evenly distributed clamping pressure improves stability.

Choose Appropriate Accessories:
Use low-profile Picatinny rings or red dot mounts to maximize space and keep your optic at the correct shooting height.
