BKL-620 Ring Mount Level – Scope Bubble Level Accessory

The BKL-620 Ring Mount Level is a compact accessory designed to attach directly to a BKL scope mount (one-piece or two-piece) and help shooters keep their rifle perfectly level during setup and use. Ensuring your rifle isn’t canted (tilted sideways) improves lateral accuracy and consistency — especially for precision shooting, competition, and long-range targets.

Key Features

Integrated Bubble Level:
• Includes a built-in spirit (bubble) level that lets you visually confirm that your rifle and optic are level — helping eliminate cant error that can shift your point of impact.

Easy Mounting:
• Designed to mount quickly and securely to any BKL one-piece or two-piece scope mount, making it simple to add precision leveling to your optics setup without extra tools or adapters.

Compatibility with Scope Mounts:
• Works with BKL ring mounts and is tailored to fit ring-style bases commonly used on dovetail-rail rifles and airguns.

Helps Improve Accuracy:
• Keeping your rifle level before firing reduces scope cant — a subtle tilt of the rifle that can cause bullets or pellets to drift off target at range. This accessory supports more consistent shot placement.

Performance & Practical Use

Adding a level to your scope mount helps you verify that your rifle is held straight in both the horizontal and vertical planes before each shot. This is especially useful when setting up for long-range shots or practicing precision shooting, where even slight tilt can introduce aiming errors. The compact bubble level clips on easily to existing BKL mounts so you can keep both eyes on situational awareness and shooting fundamentals instead of guess-working firearm alignment.

This tool is not a mount by itself; it supplements your existing BKL ring setup. It’s a simple yet effective way to maintain consistency shot after shot.

Best Suited For:

✔ Long-range precision shooters
✔ Competition shooters needing consistent rifle setup
✔ Hunters who want a quick reference for alignment
✔ Any shooter mounting optics on BKL ring mounts

User Tips

Level During Installation:
After mounting your scope but before tightening rings fully, use the bubble level to align the rifle and optic. This helps avoid cant-induced drift at range.

Check Periodically:
Even after zeroing, check the level during subsequent sessions — rifle transport or handling can sometimes shift rings slightly.

Use with Proper Mounts:
This accessory is meant to attach to BKL mounts; ensure your rings are compatible before buying.a
