Last year I bought a single flexible rifle length Teslong borescope with a USB connection to a computer. The computer thinks it is just a web cam. The borescope came with a small 4mm mirror, suitable for .22 bores and usable in larger bores. After a lot of use last year, I came up with three items I needed to address:
1. The included mirror needed a centering bushing for stable focus in the 9mm and .45 cal bores. I made up some 4mm by 9mm bushings to use, but this was not a perfect solution.
2. I either had to take my notebook computer to the shop or bring the firearms to my office desk to use the borescope. I was close to setting up an old computer in my shop just to use with the borescope.
3. The rifle length flexible borescope was a lot of somewhat stiff unused cable to handle when borescoping a pistol barrel. This is a hassle even in the shop, but especially on an office desk.
Teslong has expanded their offerings over the past year or so and has addressed all of my wants, for a price.
1. Teslong now offers a 4 mirror kit to use with the 4mm camera. The kit is sold separately and includes mirrors for .22, .308, 9mm, and .45 bores. Not only do the mirrors fit well in the bore, they are full diameter so the view spans a wider width of the bore than when using only the small .22 bore mirror. This is a big improvement and eliminates the in and out of focus and small view when using the borescope in centerfire pistol bores.
2. Teslong now offers two dedicated borescope monitors/recorders. I bought the 5" (latest, I think) monitor version in a kit with a case, the mirror kit, and all the cables plus a flexible rifle length borescope identical to my original borescope. This all works perfectly and doesn't take up much space on the shop bench. Now I can leave the rifle length flexible borescope and Teslong monitor in the shop and leave my notebook computer in the office.
3. Teslong now offers a 12" rigid probe pistol borescope. I have bought two of these and two additional mirror kits for use with a computer. I did not get the pistol borescope version that is cabled to work with the Teslong monitor, but that version is available.
I plan on leaving one rifle length and one pistol length borescope in New Mexico, one pistol length in my office, and the rifle length with monitor in the shop. I think all of my needs have been met. Here is a video showing the monitor and new mirrors that I used this morning in making a video of a new Primary Machine P-10F barrel.

Let me know if you have any questions. I purchased all of these items at full price myself. I will try the new barrel within the week.

for the monitor, mirror kit and borescopes, what was the price for set-up?
-
The NTG-500 kit which includes the flexible rifle borescope, monitor/recorder, mirror kit, and a nice case was $140 plus shipping from a US distributor in California. The rigid pistol borescope was $28, for use with the computer only, and the little 4 mirror kit is $20.
Also, turns out the large mirror is 12mm diameter, so too large for a .45, so I will be using the 8.3mm mirror for the 9mm bore in the .45 cal 97B"E" pistol barrel also. The 8.3mm mirror makes 'scoping the 9mm barrels easy.

not too bad for a full kit in a box. 8)
But then if I start using it I will have to clean more. :o
