Inexpensive Bore Scope Review......Article

Lots of discussion on n the various forums about all the under $50 Bore Scopes available on Ebay and Amazon. I decided to buy a few and test them out to see if they were viable for gunsmithing and general firearm inspection. I wrote an article with loads of actual videos and posted it on my web site...

Lots of folks had issues with them burning out at the time. I didn't suffer that, but they didn't have the ...

That they were a bit difficult to follow. Henry Arnold, the owner of MachTach saw my article and res...
