SZWRSKJ Scope Level Mounting Kit Instruction Manual
Universal Bubble Leveling Tool with High-Precision System
Introduction
Thank you for choosing the SZWRSKJ Scope Level Mounting Kit. This universal bubble leveling tool is designed to assist in the precise installation and leveling of rifle scopes, ensuring optimal accuracy. This manual provides detailed instructions for setup, operation, maintenance, and troubleshooting to help you get the most out of your new leveling system.
Product Overview
Components
- Magnetic Scope Level: Features a strong magnetic bottom for secure attachment to metallic surfaces, typically the scope turret or receiver.
- Adjustable Barrel Clamp Level: Designed to attach to the rifle barrel, featuring non-marring pads and an adjustable clamp for various barrel diameters (up to 1.62 inches).
- Hex Key: For adjusting the barrel clamp level.
Key Features
- High-Precision Bubble Levels: Ensures accurate leveling for improved shooting performance.
- Solid Aluminum Alloy Construction: Durable and lightweight design.
- Non-Marring Pads: Protects firearm finishes from scratches during use.
- Strong Magnetic Bottom: Provides stability for the scope level on ferrous metals.

Setup and Calibration
Before mounting your scope, it is crucial to ensure both the rifle and the leveling tools are properly calibrated and stable.
- Prepare the Rifle: Place your rifle on a stable surface, such as a shooting rest or bipod with a sandbag, ensuring it is secure and cannot move during the leveling process.
- Level the Rifle (Receiver):
- Place the magnetic scope level directly on a flat, level surface of the rifle's receiver (e.g., the Picatinny rail or a flat top receiver).
- Adjust the rifle's position until the bubble in the magnetic scope level is perfectly centered. This establishes a true level reference for your rifle.
- Calibrate the Barrel Clamp Level:
- Attach the adjustable barrel clamp level to the rifle barrel, ensuring the non-marring pads are properly seated.
- Adjust the barrel clamp level using the hex key until its bubble also aligns perfectly with the centered bubble on the receiver. This synchronizes the barrel level with the rifle's true level.
- Note: Some users may find it beneficial to verify the calibration of the barrel clamp level on a known level surface prior to attaching it to the rifle.

Operating Instructions (Scope Leveling)
Once the rifle and barrel clamp level are calibrated, proceed with scope installation and leveling.
- Mount the Scope: Securely mount your scope to the rifle using appropriate scope rings, but do not fully tighten the rings yet. The scope should be able to rotate freely within the rings.
- Position the Magnetic Scope Level: Place the magnetic scope level on top of the scope's turret cap or a flat surface on the scope body. Ensure it is stable.
- Level the Scope:
- While observing both the barrel clamp level and the magnetic scope level, gently rotate the scope within its rings until the bubble in the magnetic scope level is perfectly centered.
- Confirm that the barrel clamp level's bubble remains centered, indicating the rifle itself is still level.
- Tighten Scope Rings: Once both levels indicate a perfectly level setup, carefully and evenly tighten the scope ring screws according to the scope manufacturer's specifications. Ensure the scope does not shift during tightening.
- Final Verification: After tightening, re-check both levels to confirm that the scope remains perfectly level relative to the rifle.

Maintenance
Proper maintenance will ensure the longevity and accuracy of your SZWRSKJ Scope Level Mounting Kit.
- Cleaning: After each use, wipe down the levels with a clean, dry, soft cloth to remove any dust, dirt, or residue. Avoid using harsh chemicals or abrasive materials that could damage the finish or the bubble vials.
- Storage: Store the leveling kit in its original protective case or a similar padded container to prevent damage from impacts or scratches. Keep it in a dry environment away from extreme temperatures.
- Inspection: Periodically inspect the levels for any signs of damage, such as cracks in the bubble vials, loose components, or wear on the non-marring pads. Ensure the hex screws on the barrel clamp level are secure.
- Re-calibration Check: It is recommended to periodically re-check the calibration of both levels on a known level surface, especially if the kit has been dropped or subjected to rough handling.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bubble not centering on magnetic level. | Rifle or surface is not level; magnetic level is not seated properly. | Ensure rifle is stable and level. Re-position the magnetic level on a flat surface. |
| Barrel clamp level bubble is off-center after initial setup. | Level requires calibration; rifle shifted. | Re-calibrate the barrel clamp level using the hex key while the rifle is level. Ensure rifle stability. |
| Scope shifts during tightening of rings. | Rings not tightened evenly; insufficient friction. | Tighten ring screws incrementally and evenly. Apply proper torque as per scope ring manufacturer's instructions. |
| Magnetic level does not adhere well. | Surface is non-ferrous (e.g., aluminum scope body); surface is dirty. | Ensure the surface is made of a ferrous metal. Clean the contact surface and the magnet. |
