The Teslong NTG100H is a 26-inch long rigid rifle borescope. It is an ideal gunsmith tool that helps verify how well your barrel has been cleaned. Carbon deposits build up as you shoot and can start to degrade your accuracy. This flexible borescope helps you see the deposits in the lands and grooves of the rifling and is a great aid when cleaning your barrel. The flexible design of this borescope allows it to be rolled into a compact size that travels well.
