Buying Guide: How to Choose the Best Bore Scope for Rifles

Bore scopes for rifles are technical inspection tools that let you see inside your firearm’s barrel, helping you spot fouling, corrosion, and wear that can impact accuracy and safety. Choosing the right model involves balancing probe flexibility, viewing method, device compatibility, and ease of use. Many buyers are surprised by the variety of connection types and the importance of probe diameter for fitting different calibers.

Choosing Between Flexible and Rigid Probes

The choice between a flexible and rigid probe depends on your rifle type and inspection needs. Flexible probes are best for reaching through long barrels or navigating complex paths, while rigid probes provide better control and are easier to guide precisely. Consider your typical cleaning routine and whether you need to access tight curves or just want straightforward, stable inspection.

Built-In Screen vs. Device-Based Viewing

Some borescopes come with their own screen, making them plug-and-play and independent of phones or computers. Others require connection to a device, which can offer a larger or higher-resolution display but may involve app setup or compatibility checks. If you want immediate, hassle-free viewing, a built-in screen is ideal. If you prefer using your existing devices or need to save images directly to your phone or computer, choose a compatible cable or wireless model.

Device Compatibility and Connectivity

Not all borescopes work with every device. Some are iOS-only, Android-only, or require a specific USB or USB-C port. Wireless models usually support both iOS and Android, but may not work with computers. Always check compatibility with your preferred device before purchasing to avoid frustration.

Mirror and Probe Size Considerations

Interchangeable mirrors and probe diameters determine which calibers you can inspect. Smaller probes fit more barrels but may be less robust. Multiple mirror sizes let you adapt to different firearms. If you own several rifles of varying calibers, look for a kit with a range of mirror options.

Final Buying Advice

Selecting the right rifle borescope comes down to matching your inspection needs, device preferences, and firearm collection. Avoid overbuying features you won’t use, but don’t underbuy if you own multiple rifles or need thorough documentation.

FAQ For Bore Scopes For Rifles

1. What size probe do I need for my rifle?

Most modern rifle borescopes with a 0.2-inch (5mm) or smaller probe fit .20 caliber and larger barrels. For smaller bores, choose an ultra-slim probe.

2. Do I need a borescope with a built-in screen?

A built-in screen offers immediate, standalone viewing. If you prefer using your phone or computer, a screenless model may be more convenient.

3. Are wireless borescopes as reliable as wired models?

Wireless borescopes are convenient and portable but may have lower image quality or require app setup. Wired models often provide more consistent performance.

4. Can I use the same borescope for multiple calibers?

Yes, if the borescope includes interchangeable mirrors and a small enough probe, it can inspect a range of barrel sizes.

5. How do I clean and maintain my borescope?

Wipe the probe with a soft, damp cloth after use. Ensure it is dry before storage and avoid bending rigid probes excessively.

6. Will my borescope work with my iPhone or Android device?

Check the product’s compatibility. Some models support iOS, Android, or both, while others require a computer connection.
