10 Best Borescope For Rifle Barrels 2025 in the United States

The Teslong Rifle Borescope is designed specifically for inspecting rifle barrels .20 caliber and larger, making it a useful tool for gun owners who want to maintain their rifles by checking for cleanliness, wear, and damage inside the barrel. Its 0.2-inch (5mm) diameter probe is slim enough to fit most rifle barrels, and the 45-inch flexible cable lets you inspect from the muzzle all the way to the chamber in one go. This length is convenient for thorough examination without needing multiple passes.

The borescope connects easily to a wide range of devices, including the latest iPhone 15/16 via USB-C, as well as Windows, Mac, and older Android devices, offering great versatility for viewing and recording inspection footage. The camera has HD quality with a close-focus lens, and it comes with six different mirrors that help reduce glare and adapt to various barrel calibers between .20 and .50, improving visibility of hard-to-see areas. Six adjustable LED lights provide ample illumination to highlight details inside the barrel, which is essential since barrels are dark and narrow. The probe is waterproof and has a corrosion-resistant metal casing, adding durability and making it easy to clean after use.

The borescope does not have autofocus, so some manual adjustment might be needed to get sharp images. It also lacks a built-in display, so users must rely on their phone or computer screen for viewing. This setup suits those comfortable using mobile devices or PCs, but might be less ideal for users wanting a standalone device. The Teslong offers a strong combination of flexibility, image quality, and durability at a reasonable price, making it a solid choice for hobbyist shooters, gunsmiths, or anyone seeking a reliable way to maintain their rifle barrels.

The DXZtoz Dual-Lens Articulating Borescope is designed to enhance inspection tasks, especially for mechanics and hobbyists, including those interested in examining rifle barrels. One of its standout features is the two-way articulation, allowing users to easily navigate tight spaces and tricky angles, which can be a game changer when trying to get a clear view in complex areas. The 5-inch dual screen provides a high-definition image at 1080p, and the split-screen capability means you can view different angles simultaneously without fumbling with adjustments. This is particularly beneficial when inspecting hard-to-reach areas, as it reduces the time spent re-positioning the camera.

This borescope is well-suited for those who need a reliable and flexible inspection tool, especially for automotive or home applications. Shooters and gun enthusiasts should consider its focal range limits and the gooseneck's adaptability when assessing its suitability for rifle barrel inspections.

The Teslong Rifle Borescope with a 5-inch monitor is a comprehensive tool for rifle barrel inspection. Its 0.2-inch diameter probe fits easily into barrels as small as .20 caliber, making it versatile for various firearms. The 45-inch flexible probe and close-focusing camera allow for detailed inspection of barrel cleanliness, rifling wear, and other potential issues.

The built-in 5-inch HD IPS screen eliminates the need for additional devices, providing a straightforward plug-and-play experience. The 3500mAh rechargeable battery ensures long usage without frequent recharging. The six adjustable LED lights and detachable 90° side-view mirror enhance visibility, even in the darkest sections of the barrel.

Additionally, the device supports both picture and video recording, with a built-in 32GB Micro SD card for ample storage. The built-in microphone and speaker allow for video recording with audio, and playback is possible on the monitor itself. However, the product's relatively high weight of 2.31 pounds and its bulky package dimensions might make it less portable. This borescope is highly suitable for gun enthusiasts and professionals who need a reliable tool for regular maintenance and detailed inspections of their firearms.
