This Teslong model emphasizes rifle inspection via Android OTG compatibility and PC/Mac use. It’s not iPhone/iPad compatible, so plan accordingly if you’re in Apple ecosystems. The 0.2-inch probe enables entry into .20 caliber and larger barrels for cleanliness checks, wear assessment, rifling condition, and fouling. Includes right-angle mirrors to aid inspection through the bore and identify potential issues before they affect performance.
Designed to save time and money by supporting detailed bore evaluation, this unit targets users who primarily rely on Android devices or desktop computers for analysis.

The NTG100H-C brings USB-C convenience to rifle bore inspections with a built-in lighting system and a set of mirrors designed for multi-caliber use. The 0.2-inch probe is suitable for .20 caliber and larger barrels, enabling checks for cleanliness, throat wear, tool marks, rifling wear, and chamber damage. The upgraded USB-C interface ensures broader compatibility with modern devices while preserving wired compatibility with Windows/Mac through the original cables.
Use this model to blend on-device viewing with the flexibility of multiple device ecosystems, prioritizing quick setup and reliable image capture during inspections.
Teslong 4.5 Inch Screen Borescope for Rifles
This model features a built-in 4.5-inch IPS color screen, removing the need for external devices. It supports direct viewing and recording on a 1920×1080 display, with images saved to a 32GB Micro SD card. The 0.2-inch probe fits .20 caliber and larger rifles, and the 45-inch flexible camera probe covers the bore length without frequent repositioning. It offers plug-and-play simplicity for immediate inspections on the range or bench.
Ideal for users who want a self-contained solution with straightforward operation and no dependency on smartphones or computers for viewing.
Teslong Rigid 26-Inch Borescope with 5-Inch Monitor
A long, rigid insertion tube combined with a 5-inch IPS screen provides stable handling and a broad view of the bore. The 0.2-inch probe entry supports inspection of barrels as small as .20 caliber, with the ability to diagnose cleanliness, throat wear, rifling wear, and chamber damage. On-board recording and easy viewing make this a strong pick for serious rifle maintenance and testing in varied environments.
The 26-inch rigid design minimizes the need for frequent repositioning, enabling faster, more comprehensive inspections along the entire bore.
Buying Guide: Key Purchase Considerations
- Display and compatibility: Decide whether you want a smartphone/PC-connected borescope (USB-C or Micro-USB) or a standalone screen. Consider your device ecosystem (iPhone vs Android) and whether you prefer plug-and-play viewing or flexible software options.
- Probe diameter and caliber fit: Ensure the 0.2-inch probe accommodates calibers you intend to inspect (.20 cal and larger). A smaller probe helps access tight throats and deep rifling areas.
- Mirror set and optics: Look for multiple mirrors (45° angles and additional 35° options) to reduce glare and capture critical bore features across different calibers.
- Length and handling: For longer barrels, a rigid or semi-rigid insertion tube (such as 26 inches) can improve scope control and reduce repositioning; shorter flexible probes work well for quick checks in tight spaces.
- Storage, power, and durability: Consider models with robust build quality, easy storage cases, and reliable power options (USB-powered or internal batteries) for field use.
- Documentation and support: Opt for brands with clear manuals, software compatibility notes, and responsive customer support to minimize downtime during inspections.
- Price-to-value balance: Weigh feature sets like built-in screens, lighting, and mirror sets against the need for cross-device compatibility and long-term maintenance goals.
When selecting a rifle borescope, align the tool with your primary workflow—field inspections, bench diagnostics, or range zeroing. For multi-caliber use, prioritize models with versatile mirrors and OTG compatibility. If you frequently inspect from a phone or tablet, USB-C variants can offer faster setup and streamlined viewing. For standalone reliability, models with integrated high-resolution screens provide immediate feedback without relying on external devices.
