7 things to know about airgun scopes

Introduction

This tutorial covers essential information about airgun scopes, including their features, types, and installation. Whether you're a beginner or looking to refine your knowledge, this guide will help you understand the key aspects of selecting and mounting an air rifle scope effectively.

Step 1: Understand Scope Tube Sizes

• Scope tubes generally come in three sizes:
  • 1 inch
  • 30 mm
  • 34 mm
• Choosing the right size affects the scope's light transmission and mounting options.
• Ensure compatibility with your rifle's mounting system.

Step 2: Learn About Parallax Adjustment

• Parallax adjustment is crucial for focusing your scope at various distances.
• There are two types of adjustments:
  • Front Focus: Adjusts the objective lens directly.
  • Side Focus: Uses a knob on the side of the scope for adjustments.
• Proper parallax setting ensures that your reticle stays on target, improving accuracy.

Step 3: Differentiate Between Focal Planes

• Understand the two types of focal planes:
  • First Focal Plane (FFP): The reticle size changes with magnification, allowing for accurate holdovers at any zoom level. Ideal for long-range shooting.
  • Second Focal Plane (SFP): The reticle size remains constant regardless of magnification. Best for general use where precise holdovers aren’t critical.
• Choose based on your shooting style and range requirements.

Step 4: Explore Reticle Types

• Familiarize yourself with various reticle designs:
  • Duplex: Simple crosshairs; versatile for general use.
  • Mil-Dot: Includes dots for range estimation; useful for tactical shooting.
  • Christmas Tree: Offers a series of markings for windage and elevation; great for precise adjustments.
• Select a reticle that fits your shooting needs.

Step 5: Consider Springer Ratings

• Spring-rated scopes are designed to withstand the unique recoil of spring-powered airguns.
• Check for a rating if you're using a springer to avoid damage to the scope.

Step 6: Choose the Right Mounts

• Mounts come in various styles:
  • Weaver or Picatinny: Choose based on your rail system.
  • 1-piece or 2-piece mounts: 1-piece offers more stability, while 2-piece allows for flexibility.
• Heights are categorized as low, medium, or high; select based on your shooting position and scope size.
• Consider droop compensation mounts if your airgun has a barrel droop.

Step 7: Follow Proper Mounting Procedures

• To mount your scope effectively, follow these steps:
  1. Secure the Base: Attach the mounts to the rifle using the appropriate screws.
  2. Position the Scope: Place the scope in the mounts, ensuring it is level.
  3. Adjust Eye Relief: Move the scope until you achieve a comfortable sight picture.
  4. Tighten Mounts: Gradually tighten the mount screws to secure the scope; avoid overtightening.
  5. Check Alignment: Use a bore sight if necessary to ensure proper alignment with the barrel.
• For detailed guidance, consider using resources like Fix It Sticks for installation tips.

Conclusion

Understanding airgun scopes is crucial for enhancing your shooting experience. By familiarizing yourself with tube sizes, parallax adjustment, focal planes, reticle types, springer ratings, mounts, and proper installation, you can make informed decisions that improve accuracy and performance. Take the time to select the right scope for your needs, and enjoy your shooting with confidence!
