Protecting your valuable rifle scope is crucial, and Butler Creek scope caps are a popular choice among shooters for their durability and ease of use. However, with a range of sizes available, finding the perfect fit for your scope can be a little tricky. This guide will help you understand Butler Creek scope cap sizing and ensure you choose the right ones for optimal protection.
Understanding Butler Creek Scope Cap Sizing
Butler Creek scope caps are primarily identified by their objective lens diameter and eyepiece lens diameter. These measurements are usually found on the scope itself, often engraved near the lens. It's crucial to measure both to ensure you get a perfectly fitting set. Don't rely on the scope's model number alone; direct measurement is always best.
Measuring Your Scope Lenses
- Objective Lens: This is the larger lens at the front of your scope. Use a ruler or calipers to measure the diameter of the lens in millimeters (mm).
- Eyepiece Lens: This is the smaller lens at the rear of your scope, through which you look. Measure its diameter in millimeters (mm) as well.
You'll need both measurements to select the correct Butler Creek scope caps. Their packaging clearly displays the size they fit, typically listed as "Objective Lens Diameter - Eyepiece Lens Diameter" (e.g., 44mm - 40mm).
Identifying Your Scope's Lens Sizes: Common Scenarios & Tips
Sometimes, finding the exact measurements can be challenging. Here's how to approach common situations:
Scenario 1: The Measurements Are Clearly Marked on the Scope
This is the ideal scenario. Simply note the objective and eyepiece lens diameters, and you have your sizes.
Scenario 2: The Measurements Are Difficult to Find on the Scope
If the markings are faint or absent, you might need to use a digital caliper for precise measurements. Ensure you're measuring the lens diameter, not the outer diameter of the scope housing.
Scenario 3: You Only Know the Scope Model Number
While you might be able to find the lens sizes using the scope's model number and online resources, direct measurement is always the most reliable method. Different manufacturers might use slightly varied lens sizes even within the same model line.
Scenario 4: You Don't Have Your Scope on Hand
If ordering online and your scope isn't readily accessible, contact the scope manufacturer or retailer. They should be able to provide the lens diameter measurements.

Butler Creek offers several lines of scope caps, each with its own features and advantages:

Conclusion: Accurate Measurement is Key
Choosing the correct Butler Creek scope caps hinges on accurate measurement of your scope's objective and eyepiece lenses. By carefully measuring these diameters and comparing them to the manufacturer's sizing charts, you can ensure a perfect fit and protect your valuable investment.
