Teslong 5-Mirror Set for Rifle Borescopes - These fit on Teslong NTG100-series borescopes, and include 5 mm, 6 mm, 7 mm, 8.5 mm, and 10 mm diameters to fit .22, .243, .30, .38, .40 caliber, and more barrel sizes. These mirrors are NOT compatible with the NTG200 Focus & Fold borescope.

This set includes one of each diameter side-view mirror:

0.2 in (5 mm)

0.23 in (6 mm)

0.27 in (7 mm)

0.33 in (8.5 mm)

Description:

This kit allows you to see more of the lands and grooves inside of large-caliber rifle barrels than you would with just the standard 0.20-diameter mirror.

These mirrors also help keep your borescope centered inside the barrel and thus maintain a more consistent focus as you rotate the borescope probe.
