Borescope Inspecting a Bartlein 6 Creedmoor Barrel After 700 Rounds

This video uses a borescope to check out my Bartlein 6 Creedmoor barrel after 700 rounds to check out a carbon ring, throat erosion, copper and carbon fouling and compare it to a brand new Barlein 6GT barrel.
Here's a link to the borescope I purchased. It's an affiliate link so if you buy using the link it benefits the channel.
