What I Learned After Buying 4 Firearm Borescopes

I’m teaching myself gunsmithing – trying to.

We’re also selling 20th-century gun parts on eBay.

Thus it’s no stretch that a borescope would be a useful tool

Like I tell people as I learn the gunsmith trade – “it’s just as easy to fuck up a $100 gun as a $600 gun”.

Here’s another example of a really cheap gun ($20) restoration.

I work on a lot of Ring of Fire handguns.

Purchase One – Starting with the bottom of this list – “3 in 1 for Android Type‑C Mobile Phone” was returned a couple of minutes after opening the box.

The USB-C connector would not hold onto my relatively new phone, so what’s the point?

Purchase Two – “EFUTONPRO Industrial Endoscope Camera 3.9mm Borescope” which I wish I returned but was busy and missed the return window.

After about an hour of fighting with the piece of shit, I figured out I needed a micro card and inserted it into the unit.

I could never get it to record video, just images. Still, you needed to remove the micro card (no easy feat – it’s a fucking micro card) and insert it into a full-size memory card adapter, AND THEN insert THAT into one of the few PCs I own that still has memory card slots.

The unit doesn’t charge but will work if plugged into a PC’s USB port so I am gifting it to my motorcycle riding buddy  “Crash” (you can’t make this shit up).

He is a restoration expert of vintage guitars and would like to inspect interior instrument bodies that require a flexible scope –

Both flexible and rigid cameras work for firearm barrels.

Unit Three – “3 in 1 for Android Type‑C Mobile Phone” – held on the cell phone C Port and produced images and videos but neither the manufactures mobile app mobile or PC download would allow for the creation of an MP.4 – returned the same day it was received.

Unit Four the TESLONG is my keeper – A 9-inch rigid camera is fine for now as I’m not wading into long guns- just yet.

Here’s my first borescope video (with the unit above). Smith & Wesson 469 revolver barrel.

I already uploaded the MP.4 to that barrels eBay listing.

Judging by the prices I paid, firearm borescopes are like most products – you get what you pay for.
