Mounting a rifle scope correctly is crucial for accurate shooting. A level scope ensures proper alignment and prevents frustrating misses caused by cant (the scope being tilted). This guide will walk you through the process, covering different mounting methods and troubleshooting common issues.
Essential Tools and Equipment
Before you begin, gather the necessary tools:
- Rifle Scope: Obviously! Ensure it's compatible with your rifle's receiver.
- Rifle Scope Mounts: Choose mounts appropriate for your rifle's type (e.g., Weaver, Picatinny) and scope's ring size. High-quality mounts are essential for stability and accuracy.
- Screwdrivers: You'll need the correct size screwdrivers for your scope rings and mounts.
- Torque Wrench (Highly Recommended): Over-tightening can damage your scope or mounts. A torque wrench allows you to apply the manufacturer's recommended pressure.
- Level: A small, bubble level specifically designed for scope mounting is ideal. Alternatively, a high-quality digital level can be used.
- Mounting Kit (If Needed): Some rifles may require additional parts for scope mounting, such as bases or rings.
- Cleaning Supplies: Keep your rifle and scope clean to prevent scratching or damaging the components.
Step-by-Step Guide to Level Scope Mounting
1. Prepare Your Rifle: Clean your rifle thoroughly, focusing on the receiver area where the scope mounts will attach. Remove any existing mounts or debris.
2. Attach the Scope Mounts (if necessary): If your rifle doesn't have pre-installed Picatinny or Weaver rails, you'll first need to attach scope bases. Ensure they are properly aligned and securely fastened.
3. Mount the Scope Rings: Carefully place your scope rings onto the mounts or rails, making sure they are positioned correctly.
4. Install the Scope: Gently place the scope into the rings, ensuring it's seated evenly.
5. Initial Leveling: Use your level to check the scope's level both horizontally and vertically. Most scopes have a level built into the tube, which is a convenient feature to utilise. If your scope lacks a built-in level, a small bubble level is the best approach. This initial check ensures the rough alignment.
6. Tighten the Rings (Gradually and Carefully): Use your fingers to initially tighten the scope ring screws. Then, use your screwdriver to tighten them further. Crucially, if you have a torque wrench, use it. Do not over-tighten! Over-tightening can damage the scope or rings. Rotate the screws in stages, ensuring the rings remain properly leveled.
7. Final Leveling Check: After tightening, use your level to perform a final check for horizontal and vertical alignment. Make minor adjustments by loosening the rings slightly and repositioning the scope if needed. Repeat steps 6 and 7 until the scope is perfectly level.
8. Test Fire (At a Safe Range): After mounting the scope, it's essential to test fire your rifle at a safe range, using a proper backstop. Start with small groups to check for zero.
Troubleshooting Common Issues
- Scope is not level: Double-check your mount alignment, ensure the rings are seated correctly, and verify your use of the correct torque. If the problem persists, your mounts or rifle may be out of alignment. Consider professional help.
- Scope is loose: Over time, screws may loosen. Regularly inspect and tighten the scope ring screws.
- Difficulty leveling: A warped receiver can make leveling difficult. Check the receiver for any bends or damage and seek professional assistance if necessary.
Choosing the Right Scope Mounts and Rings
Selecting high-quality scope mounts and rings is vital. Factors to consider include:
- Material: Aluminum or steel are common materials. Steel is stronger but heavier.
- Type: Weaver and Picatinny are standard rail systems. Ensure compatibility with your rifle.
- Ring Size: Match the ring size to your scope's tube diameter.
- Height: Ring height affects eye relief and clearance. Choose the appropriate height for your scope and rifle.
By following these steps and paying attention to detail, you can successfully mount your rifle scope level, ensuring accurate shooting and a positive shooting experience. Remember, safety is paramount – always practice responsible firearm handling.
