Teslong Flexible Rifle Borescope 0.2inch Dia Fits .20 Caliber & Larger NTG500
Stop guessing, Teslong Borescopes are a useful tool that will let you see what’s really going on inside your barrel. Our TESLONG NTG-series borescopes are designed to be interchangeable, allowing you to switch between a 26″ rigid borescope probe to use for your longer rifles, or a 10″ rigid, pistol borescope probe to use for your handguns.
