Best Rifle Borescopes with Screens for Accurate Barrel Inspections

A borescope for a rifle is a small camera that can go inside the barrel for inspection purposes. Maintaining rifles can be a chore when you need to take everything apart and still cannot see clearly into the barrel. A borescope removes steps by allowing access to the smallest parts of a rifle with ease. Even better, the devices can take both images and video for better diagnostics.

Borescopes with a screen are portable devices that typically include two parts connected by a cable. You usually find the inspecting probe at one end and a screen or monitor at the other end. The monitor lets you see the live view from the camera and view stored photos from the internal memory. You don't need to connect to another device or download an app to your phone; simply turn it on and get started inspecting your rifle. It is a useful multi-purpose diagnostic tool available with either a flexible or rigid camera probe.

A borescope can help you inspect guns before purchase, make sure a weapon is clean, identify areas of fouling in the barrel, check for defects, and inspect the insides of cases, silencers, and other components. In addition, the camera provides crisp, clear, and up-close views inside of smaller items. Overall, a borescope can save you time, money, and energy as it cuts the workload down dramatically when it comes to cleaning and repairs.

Turn on the monitor by pressing the power button and make sure it’s fully charged. The borescope is plug-and-play so once it is on you should be ready to go, however most of our models include a selection of caliber-specific mirrors so you'll want to install the largest mirror that will fit into the gun barrel you are inspecting. Insert the borescope into the rifle, slowly taking your time and wait for the camera to come into focus. While in use, take photos or video along with inspecting the device. After, wash the borescope and store all the pieces in a storage container in a cool, dry location.

The NTG200H rifle borescope with a 5-inch screen offers the best features that we offer with a screen. This is our top-of-the-line model including a 26-inch long rigid probe that folds to 14 inches for easy travel, plus an easy-to-focus design that is the quickest way to achieve a sharp image. Plus it includes a robust 5-inch screen monitor to view your inspection as well as the photos and videos that are stored on its 32 GB memory card. It’s easy to use plug and play with an LED ring light and 5-piece side-view mirror kit, and it’s ready to take pictures and record video. Finally, the borescope fits gun barrels that are .22 caliber and larger.

The borescopes on this page already include a screen, so you need to use the included screen to take photos and videos, and then you can remove the micro SD card and insert it into your laptop to view that content. If you prefer to view all the images on a larger screen, consider getting a USB rifle borescope as these can connect to a laptop with an included USB cord and are generally less expensive.

You can use a gun borescope for non-gun inspections, but they are optimized for looking inside a gun barrel, with a fixed focal distance of about 0.4 to 0.6 inch on most models, so it won’t work for all applications. The side-view mirrors are best for up-close surface inspections and won’t have as wide of a field of view as our dual-lens camera probes. Gun borescopes are typically rigid probes because that makes them easier to handle and turn inside the barrel, but it’s not a requirement. Our regular inspection endoscopes are suitable for gun inspection so long as they fit down the barrel. Single-lens camera probes will work the best because they include a right-angle mirror accessory. The right-angle camera on our dual camera lenses will NOT work well to inspect the flutes inside of a rifle barrel because they usually are too close to the lens and the focus will be blurry.

While it may be possible to rent a gun borescope, we do not offer that service and believe it is better to simply buy one. Our entry-level USB pistol borescopes are inexpensive and will work with any Windows PC, Mac OSX computer, or Android mobile device - so they are not expensive to own.

Yes, you can find the 5-Mirror Set of caliber-specific mirrors included with all of the borescopes on this collection page as well as on our accessory page. Teslong borescopes usually come with a 0.20-inch diameter mirror to fit .22 caliber or larger barrels. While these mirrors will fit in larger barrels just fine they will have some slop and move around, which can affect focus and image quality. To get the best focus and see the largest area we offer the 5-Mirror Set designed to inspect .22, .243, .30, .38, and .40 caliber barrels.

Both sizes show the same 854x480 picture and save 1920x1080 photos and 1280x720 video to the included 32 GB card. The 5-inch models (NTG500H, NTG500 and NTG200H 5″) give you a larger view and a 3500 mAh battery; the 4.5-inch models (NTG450H, NTG450 and NTG200H 4.5″) use a 2500 mAh battery. Teslong lists 4–5 hours of use for the NTG200H with the 5-inch monitor and 4 hours with the 4.5-inch monitor.

Both use a 26 in rigid stainless probe and come with a 5-inch screen option. The NTG500H has fixed focus (0.4–0.6 in), set for viewing the bore wall in the side-view mirror. The NTG200H Focus and Fold adds internal manual focus from 0.4 in to infinity and a probe that folds to 14 in for storage. Note that the NTG200H mirror set is not compatible with older Teslong borescopes.

The 26 in rigid probe (NTG500H, NTG450H, NTG200H) is easier to aim and turn inside the bore and suits most rifle and pistol barrels. The 45 in flexible probe (NTG500, NTG450) reaches further, which helps with longer barrels.
