Sightron Target Knob re-set

[Harold M]

Hopefully someone has the answer. I would like to re-set the knobs on my SIII to zero. The instruction says what size allen key to use - either a 1.5 mm or the next size up in 64ths. I tried every metric and inch key and bit I have, one being the 1.5 mm, and nothing works. These are the knobs with the 3 grub screws around the circumference of the knob, not the ones with the torx through the center of the top. Anyone know what to do?

Try a 1/16 th inch allen wrench. That's what mine takes. Good luck!

Thanks. My 1/16 doesn't do the job. Maybe buy another and hope for a better fit. Does your 1/16" fit well?

That's what fits my Sightron 6x24 scope. If a 1/16" doesn't work I do not know what to tell ya. Is it a allen type set? Dave

They used to supply one in the box with the instructions and a yellow lens cleaning cloth. If you can’t find one, let me know and I will send you one. I have purchased enough Sightrons over the years I’m sure I have a spare floating around somewhere.

Yep one in every box, that's why I have a jar full of Allen keys...

Hah! There was a bag with the appropriate wrench stuck under the bag with the yellow cloth! Never noticed it.

Now, I discovered that one of the 3 holes in the windage knob is missing its grub screw. Of course, it was the one easiest to get to, and I was trying to make an allen wrench fit the screw that wasn't there. Don't suppose anyone has a spare grub screw.

Thanks for helping me.
