I know this thread is about borescopes and the following is relevant as it pertains to the health/condition of the muzzle/crown of your precision rifle barrel. I never really understood why you would use a bore guide on the chamber end but not on the muzzle crown end. A jag and rod will drag and strike the muzzle crown area hundreds if not thousands of times cleaning during the life of a barrel. I created a simple bore guide for the muzzle crown end and it works really well. We have numerous sizes. There are some good videos on the site too which demonstrate the issue and how the Crown Cradle works. Hope this helps and maybe is seen as a solution or least as extra insurance/precaution for the precision marksman.

Guys who can afford it buy a new barrel every year. Other guys re crown. $25.00 USD.
A good barrel for local competition might be good for 2 yrs(2K-3K rnds.).
Want to win the Super Shoot? buy 20-30 barrels. Chamber them yourself and test.....
I ordered one back in July for grins. I am not expecting much at the price point but it was cheap enough to gamble. We'll see how far past the "Estimated to ship within 6-8 weeks" it goes.
