NTG series borescopes usually come with a 0.21-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 image quality possible in larger caliber barrels use this set to inspect .188.8.131.52.40 and more calibers barrel.
