Here are some pix my twin and I snapped today -- after just 5 minutes of playing around with a $14.00 Borescope (5.5mm) with 6 LEDs from eBay ("Click Here to Activate the Link") which came in the mail this afternoon...
Here's the start of the bore: And the mid bore: The bore just before the rifling starts/chamber ends: And the chamber, with the firing pin in a "fired" state: We started this experiment using a new cleaning patch placed 1" to 2" in front of the borescope's camera & LEDs. We found you need to play with the brightness some (which is adjustable, via a switch where the camera's USB which attaches to your PC) to get the contrast correct. Once you setup a default folder for your images, taking pix is literally a snap!
I did find that you need to be careful with the cleaning patches used... The first ones I used reflected its "weave" back onto the bore -- and my twin said it was "clean pitting" we were seeing!

Anyway, by rotating the camera on its axis, and seeing the dimples move with it, I convinced him it was just a reflection (and boy, was I glad that was true!). So then I stuck a 2" patch from a white paper towel over the cloth patch (which was inserted from the opposite end versus the camera) and that left us with a nice white surface to reflect the lighting for clear images. I would actually push on the patch with the camera, very carefully, and that moved the patch back in the bore so I could then advance the camera.
I haven't played with any videos yet, but that can be done too. And I do plan to check all my leverguns sometime soon! Just to keep this posting on topic.
Overall -- NOT TOO BAD AT ALL for a $14.00 item!!!
Of course, my twin -- the cynic in the family -- now tells me: "You know... The Chinese are just using these gadgets, thanks to the loaded software you installed, to start building a database of all serious American gunowners -- so they can track you down during the upcoming invasion!"
Well, if so... Then at least I'll shoot back with a clean/known bore!!!
Tight groups!
