Teslong Bore scope

[Pres100]

I'm looking to get the Teslong, probably the WiFi version NGT100W, just have one question, will that unit have a 45 degree mirror to look at the bore side directly that will function on my 20 Caliber bore?
The listing shows it only comes with .22 /.243 /.30 /.38 /.40 size mirrors, that means NO on .20 in my thinking, but I am not sure. The unit says it will work with 20 caliber, but not sure if that just means looking down the barrel, or with a mirror.

If someone who has one that could verify, one way or another, that would be great. Thanks!

From a metric conversion standpoint 5mm = .1969" ... going to be pretty tight fit inside a 20 cal bore. I think the .2 in camera is sized appropriately for the .22 cal barrel but would have some problems in a .20 cal.

for 7mm and larger barrels the extra mirror kit helps tremendously with focus especially in a .308 barrel

Buy US made Gradient lens co borescope, superior USA made optics. Buy once cry once. One for sale on forum.

I have two Hawkeye borescopes. I've not opened either box except to check the batteries in the flashlight since I got a Teslong.

The first Teslong I purchased was the flexible one. I was so impressed with the flexible one I bought a second Teslong except I got the rigid model. Both, have exceeded my expectations, especially, when you consider how inexpensive they are.

I had a Lyman borescope before I bought my first Teslong and it was ok but the image quality of the Lyman was definitely not as good and the Lyman cost considerably more. I gave the Lyman to a friend and almost felt guilty even giving it away but he didn't have one at all so it was better than nothing.

I've used a Hawkeye at my gunsmiths before and they have a, very, good image but it's also one eye viewing through an ocular so for extended viewing they aren't really the most convenient but I do think they offer more defined detail in their image quality.

Also, Hawkeye has a "Slim" model that will let you scope 17 caliber barrels which would be nice since the Teslong only works on 20 caliber up and it's a pretty snug fit on my 20 cal barrels.

No 17's and no 20's and at the present time I'm not considering any. My flexible Teslong borescope does what I need. I probably will by the rigid tube version eventually.

I bought the Teslong NTG 45 inch flexible with the 5 mirror accessory right from Teslong. I needed it that long because I wanted to look at the barrels of some of my roundball muzzleloaders that have barrels of 36 inches long. Works well. took about literally 3 minutes to hook it up to my MAC computer and get going. First time user of anything like this. And it was a eye opener. Have one centerfire gun that looks absolutely like a sewer pipe. Most others were as I expected. Chatter marks here and there. Some carbon and copper etc.
Ordered right from Teslong on March 24th and got it today. Whenever I can order directly from the manufacturer I do unless its much cheaper from a retailer.

I ordered mine direct also.... had to get a new screen the light quit working
