airedale Posted January 19, 2023 Share Posted January 19, 2023 I picked up one of these Teslong bore scopes for checking barrels on my firearms, it can be hooked up to either a phone or a computer. I have mine setup for a phone right now but I think being hooked up the the larger screen of a computer is the way to go for much better detail. I think this is especially useful for checking the condition of my black powder rifles. I have had it for a couple of years now and paid about $60 if I remember right.
