Ought a Teslong professional borescope, what a great tool, around 87$ CDN

Got one too. They're pretty good but not quite in the class of the Hawkeye, not in the price class either! But it's a hard to beat instrument for checking your bore wear and cleaning procedures at home.

I bought one also, but like others have said, you are going to be spending more money. Here's what others have said.

Here is my borescope theory; they are wastes of money. The real and only test for me is to shoot the rifle and see how it performs. Looks don't matter one whit; performance does.
