Best 4.5-Inch Rifle Borescope With Screen
This Teslong model focuses on rifle inspection with a close-focusing sensor and a built-in 4.5-inch color IPS screen. It’s designed to view and record in 1920×1080 resolution, with a 0.2-inch diameter probe that fits barrels as small as .20 caliber. The device saves images and video to a 32GB micro SD card, enabling straightforward documentation of cleanliness, throat erosion, rifling wear, and fouling. It supports Windows PC and Android devices but is not compatible with iOS.
Key considerations include: plug-and-play operation, a long 45-inch flexible probe, and the inclusion of a right-angle mirror to simplify inspection around bends. This option suits users who want immediate on-device viewing without relying on smartphones. For those prioritizing portability and a dedicated display, this is a strong candidate.
Teslong 45-Inch Flexible Borescope For Rifles
This Teslong kit emphasizes a close-range camera paired with a long flexible insertion tube, designed to inspect inside the deepest rifle barrels. It’s compatible with Android (OTG-enabled), Windows PC, and MacBook—though not with iPhone or iPad. The 0.2-inch probe supports barrels as small as .20 caliber and helps detect cleanliness issues, tool marks, furrows, chamber damage, and fouling. The kit emphasizes time-saving and cost-saving benefits by enabling rapid diagnostics in the field or at the bench.
Considerations include platform compatibility and the need for an OTG-enabled Android device for full functionality. If you mainly use Android or a computer setup, this model offers a practical balance of portability and depth of inspection.
Teslong 5-Inch Monitor Bore Scope With 45″ Probe
This model pairs a 5-inch HD IPS LCD with a 45-inch flexible probe, creating an integrated viewing and recording system. It runs on a rechargeable battery and does not require a smartphone connection, simplifying field use. The 0.2-inch diameter probe remains suitable for .20 caliber and larger rifles, enabling thorough checks for cleanliness, erosion, rifling wear, fouling, and chamber integrity. Included is a micro SD card for storage and easy transfer of footage.
Potential drawbacks include battery life under extended inspection sessions and the need to manage the 5-inch display in tight workspaces. It’s well-suited for users seeking an all-in-one handheld inspection device with strong on-device viewing capability.
Teslong Rigid Rifle Borescope With 5-Inch Monitor
This 26-inch rigid probe model focuses on long insertion depth with a built-in 5-inch IPS screen. It’s designed for rapid inspection of rifle barrels, helping users assess cleanliness, throat erosion, tool marks, rifling wear, and fouling. The device operates as a plug-and-play solution, recording to a 32GB micro SD card. The 0.2-inch caliber-compatible probe enables straightforward entry into barrels from .20 caliber upward, reducing the need to switch between sections of the barrel during inspection.
Considerations include the rigidity of the probe, which can aid in straight-line inspection but may be less maneuverable in curved sections. This option suits users who want a stable, long-reach inspection tool with a clear display and easy storage.
Teslong USB-C Borescope For iPhone 15/16 And USB-C Android

Buying Guide: Key Purchase Considerations
- Probe type and length: Choose between flexible probes for curved sections and rigid probes for straight, long reach. Longer probes can reach deeper into the bore, but may be less maneuverable in tight areas.
- Diameter compatibility: Ensure the 0.2-inch probe fits your rifles’ barrels (commonly .20 caliber and larger). Some models include multiple mirrors to accommodate a wider range of calibers.
- Display and recording: Decide between on-device screens (4.5–5 inches) and smartphone-based viewing. Built-in storage (32GB or more) helps keep inspection footage organized.
- Mirrors and optics: A set of angled mirrors (45° or 35°) improves visibility around bends and across different calibers. Check included mirror sizes to match your barrels.
- Device compatibility: Some borescopes work with Windows/Mac/Android, others with iOS devices. If you use iPhone or iPad, prefer USB-C models or those explicitly supporting iOS.
- Ease of use: Plug-and-play operation reduces setup time. Consider whether you prefer a standalone display or a camera you connect to a smartphone or computer.
- Maintenance value: Look for kits that support diagnosing cleaning regimens, tool marks, and chamber damage, helping you save time and money on preventable repairs.
- Durability and warranty: Rifleside work requires robust construction. Check build quality, water resistance, and warranty terms for long-term use in rugged environments.
Across these options, buyers should weigh device compatibility, probe flexibility, and the level of image detail required for their rifles. For frequent fieldwork or bench inspections, a model with a built-in display and ample storage can improve workflow. For tech-savvy users who rely on phones and computers, USB-C variants that integrate with iOS and Android ecosystems offer strong cross-device capability. Consider your typical calibers, preferred inspection depth, and whether you value a long, rigid insertion depth or versatile, multi-caliber mirror options.
