Teslong Bore scope

Stainless steel, Springfield 9mm 1911

Ah, pistol, I was thinking rifle, makes sense now.

The only way to know if your gun is clean is to look at it with a borescope.

Need to figure out how to dim the LEDs from the WIN10 camera app.
To bright on the above pics.

Mine came with a little scroll wheel on the camera line that controls the brightness of the light.

So did mine. And the scroll wheel is VERY touchy.

Ahhh, you mean that little bitty teeny tiny wheel on the little back box that I can't see without my glasses

Thanks, hiding in plain sight.

Some more borescope photos...

Here's a labeled image that I made for someone a while back who was wondering what you actually see with the less expensive models like the Teslong. This is the barrel of my 2007 model CZ 452 FS in .22 LR. (The tiny spots on the mirror are debris on the mirror, not on the bore.)


Here's the barrel of my 1950 model Remington 121. This barrel's internal finish is much rougher than the CZ and the lands are less pronounced. The gun is very accurate with open sights but I've never had a scope on it to really put it to the test. With open sights it'll shoot with my open-sighted CZs if not out shoot some of them.


Here's how a typical .22 LR barrel looks after a few rounds. This one is my CZ 452 Trainer. You can see the coating of wax and a lot of powder residue. Some loads are quite a bit dirtier than this.


Here's the same 452 Trainer barrel after a quick cleaning.


Here's my Armalite AR-10 barrel as received showing residue from factory test firing.


Here's my 1970 model Browning SA-22 barrel that was perhaps the biggest shocker that I discovered with the borescope. I had shot the gun quite a bit and found it to shoot about 1.5 MOA (about .75") at 50 yards with GECO Rifle, which I consider to be very good for a factory semi-auto. After getting the borescope I was dismayed to see the chatter marks in the barrel of this gun that I find to be very well built, and which has a great reputation for quality craftsmanship. Apparently they don't hinder accuracy, or if they do, it's minimal.


Here's another that was a major shocker for me. It's my CZ 527 Varmint barrel after about 100 rounds of various types of ammo over a year or so. Between outings I patched it out with nitro solvent and maybe a worn-out brush and more solvent patches until they came out clean, then oiled it. Then when I looked down the bore with the naked eye it looked fine. The last time I had it out prior to this borescope photo it was shooting .3" groups at 100 yards with Black Hills Reman 40-grain V-Max, and .5" groups with GECO Rifle Target (the GECO used to be priced at almost bulk ammo levels prior to the Chinese virus destroying the world), so I never thought that it might be terribly dirty. To say the least, I was shocked to see the borescope images. I cleaned it with 40x bore cleaner and eventually got everything out to a pristine bore, but wow! What a shamefully dirty bore, and I wasn't even paying enough attention to notice (or had my eyesight just gotten that bad?). After this, and other revelations via the borescope, I'm now MUCH more meticulous with my cleaning.

Of course now the carbon ring has got to come out some how....
(now that I know it's there)

I bought a set of nylon Tipton dental scrapers off Amazon for like 4-5 bucks, they work pretty darn great.

I have a factory barrel that looks like somebody with turrets was pulling the buttons thru the bore. You CAN clean this bore too much. Leave a little dirty and let the copper/powder/copper/powder fill the low spots......THEN start looking at groups.

I need one of those and had no idea how inexpensive they had become. I passed on Christmas figuring I have an anniversary Feb 1st and a birthday Feb 7th so when my wife asked about Christmas I took a pass figuring a new handgun down the road in a few months. Heck in the price range of borescopes I can just tack it on to a gun. Just a matter of waiting till the stock of guns returns.

Very descriptive post.
I agree on the chatter marks not effecting accuracy as much as I would have thought.
They make it hard to keep copper out though.

Not bad price wise at all IMO, more than lunch for 2 at McDonalds, less than dinner in a decent place.

Teslong has a special model for Apple products that costs more than the Android model but it works great. Works wireless by broadcasting a Wi-Fi signal that the iPhone or iPod picks up. Works as well as the $700 Hawkeye I used to have plus the results can be recorded and shared.

 

[Walkalong]

Have a link? I couldn't find anything. Thanks

 

[herrwalther]

Here is the wireless Apple model. The other alternative is to get an adapter to work with iphone. There are plugs to convert microusb to lightning and whatever the newer ones use. My Teslong came with a type C adapter, which is what my newer Android phone uses.

Looks like that one has a rigid rod, mine has a flexible extension.
Don't know if the rod would be better or not but that is probably why it is more $.
(and of course anything to deal with Apple is more $)

Troy if you are interested in one, I believe there are apps for I phone or Android.
They have some models for about $90 that come with their own screen.
(search Amazon for Teslong bore scope)

Unfortunately I just found out my borescope will not work with my new phone! Android 10 removed functionality for usb cameras. Have to keep my old phone just to operate the borescope.

I have a Motorola Moto G7 running Android 10. I have no problems with the Teslong borescope.

Which app are you using?

Thanks, turns out I had that in a "wish list" at Amazon.

Here is another alternative, get a viewer with it.
