Thread: USB Borescope - now as good as a Hawkeye ?

Unless you are actually manufacturing barrels, a bore scope is a waste of money and about as useful as a concrete parachute. As a gunsmith I have never had use for one. All critical barrel problems can be observed with the naked eye viewing from either end (knowing what you are actually seeing also helps). The proper test is how they shoot. If they don't shoot well then you look for causes. The most common problem is damage near the muzzle which can be cured by a shorten and recrown. A borescope only lets you see imagined problems in great detail, a bit like having a complete knowledge of sausage manufacture. They taste better when you don't know!
