Teslong NTG100H-C 26" Rigid USB-C Rifle Borescope
The Teslong NTG100H-C is a specialized rigid barrel inspection camera designed to give shooters, gunsmiths, and precision reloaders a clear, detailed view of internal bore conditions. Equipped with a 26-inch stainless steel probe and a slender 0.20-inch (5.0 mm) diameter camera head, it easily navigates .20 caliber and larger rifle barrels to detect throat erosion, carbon and copper fouling, tool marks, and rifling wear. This upgraded "C" variant features native USB-C connectivity for direct plug-and-play use with modern devices—including iPhone 15/16, Android smartphones, iPads, and PCs—without requiring extra adapters or standalone monitors.
Key Features
- Direct USB-C & Multi-Device Support: Connects natively via USB-C to iPhone 15/16, modern Android phones, and USB-C iPads, while retaining legacy USB/Micro-USB compatibility for Windows and Mac computers.
- Rigid 26-Inch Stainless Steel Probe: Features laser-etched measurement markings and an adjustable rubber positioning collar to track exact camera depth and easily revisit specific trouble spots along the barrel.
- Comprehensive Multi-Caliber Mirror Set: Includes five 45° side-view mirrors (5 mm, 6 mm, 7 mm, 8.5 mm, and 10 mm) covering .20 to .50+ caliber barrels, plus an exclusive 35° anti-glare mirror that mitigates reflection on polished bore walls.
- Close-Focus Macro Optical Sensor: 1.0 MP CMOS camera engineered with a fixed focal range of 0.4–0.6 inches (10–15 mm) to deliver razor-sharp microscopic detail of lands, grooves, and chamber necks.
- Adjustable 6-LED Illumination: Integrated ring lights provide uniform, shadow-free illumination inside dark chambers with smooth manual brightness control.
- IP67 Waterproof Probe: Sealed probe construction withstands cleaning solvents, bore oils, and water rinses during post-cleaning assessments.
