These are a great bore inspection tool!
Not for that…but if your that way inclined…go for it…lol
With a 7mm diameter, how many rifles do you think it would be suitable for?
At least the Teslong starts at 22 cal, with larger adapters from there.
.30 cal and up…but the one below is 5.5mm, which I think will do .22 cal
Would be interesting to see what the quality of the picture is.
I will take some, with my 7mm one, when I get a chance…pretty damn good for the money
I bought the Teslong and it is great. Before buying it I looked at a lot on ebay and aliexpress but non had the 90 deg mirror which is really a must. After getting the Teslong and being more than satisfied with it I did buy a cheap Aliexpress one. It works but it does not really do the job. I think it is more useful as an in wall inspection camera or something along those lines. for a bore scope they need a really short focus distance and that 90 deg mirror.
What he said
They do what I want them to do…depends how ANAL you want it I guess…lol…pun intended…
