Best way to adjust focus ? In a 223 is the mirror closer to the end of the cable or farther back to get the best focus ?

I haven’t used in my 223s, but I think you switch the mirror to get the best focus. If I remember right it comes with three different ones.

Mirrors are adjusted by trial and error by moving in and out and depend on bore diameter for focusing. Not real consistent from barrel to barrel. Mine (all three models I own) seem to focus best moved inwards, but yours may vary. The various sizes of mirrors are really more to provide "fuller" images by doing a better job of centering the mirrors in the bore rather than just "flopping" around.

I have the smallest mirror in mine now, will one of the bigger mirrors fit in a 223 barrel ?

Just experiment adjusting it until the focus is correct! faster results than waiting for answers on this post.! the 2 black ones are the same mirror and the red one has an anti glare coating for extra shiny bores, or so they say.

Smallest should be .224".

With mine for .22 caliber I needed to adjust it out.

Yep...mine too. Went and checked. That's what I get for trusting to memory!

Easiest way I found is to go in through the muzzle. Insert the mirror assembly so the angled mirror is in the tube, with the screw base exposed. Hold the mirror, and screw the flexible shaft in and out until you get a good focus, then screw the lockring against the mirror. If you want to make sure it doesn't move, carefully tighten the lockring with a pair of pliers, and add a dab of nailpolish.

If you wrap a smooth masking tape around the cable to match the bore the view is more consistent as you travel and turn the scope in the barrel. Once you have the focus set it stays the same.

I have mine out by the end for 204 ruger,.223, & 6 MM for the sharpest pictures

Don’t know if they changed since I bought mine but I got 3 mirrors. 2 not colored and 1 red. I believe the red one is a different angle to reduce the light from reflecting back to the camera.

That is correct for the earlier manufactured mirrors that I have as well as the way it is listed on Teslong's current website. The five-mirror set is a 'must-have' for viewing bores larger than .224". The mirrors run up to .40+. The smallest mirror they make is for .224". You can use the bare probe on .20-caliber bores, but not with a mirror. You are reduced to only a straight down the bore look. Sadly, my .17-calibers are out of luck!

I am able to use the angled mirror on my 20 cal bores by doing the following:

Bevel the edge of the mirror slightly with hand held diamond stone or very fine wet paper

Let the mirror float slightly against the adjusting lock collar

Be gentle

Just test it. Don't need to get too OCD. There is a pretty wide range where you can see what you need.

I didn't have to do anything for it to work in my 20 cal barrel.

When my 20VT barrel was new, it wouldn’t fit. Now that it has 2400 rounds down it, the teslong fits a good 4” down from the start of the throat. Lands and all still appear intact, so apparently it’s a very subtle amount of erosion/expansion in size.

Which model do you have to fit 204?

I have the 48" M100 .2 diameter cable with the M450-NTC Monitor ,got them separately at the time it was cheaper.

I've talked with the Teslong techs told them PLEASE make a 17 cal compatible scope.
