For a 22 any clamp on type mount will work. As far as feeler guage, I think factory specs are .006 but that is more than I use. Get a set of automotive feeler guages from an auto parts store. Experiment with different gaps. Measure from the proudest chamber, which means measuring all six. .002 will be too tight. I like .004. If you use a smaller gap wipe the cylinder face with a rag every several cylinder worth of shots. Once you learn how big a gap is optional for your gun you can dispense with the guage and hold the gun up to the light while you set the gap and cycle the gun. Don't dry fire the 22 though. 🙄

Thanks for the reply. After a careful search, I found the gauge & barrel tool hiding in the pistol pack box!
I have a clamp on type mount, but would like to just replace the rear sight. I’ll probably buy a Ruger mount from
Allchin, and cross my fingers that it will fit.
If it works out, I may put up my currrent clamp on mount for sale.

I all else fails you can jury rig a 6 thou feeler gauge for pennies.
Use scissors to snip a strip about 1/2" wide & 5" long from the side of a soda can fold it in half length-ways & clamp it folded with a vice or similar to really flatten out the "U" bend. Remember to wash & dry it.
Use a nail file to deburr the edges.
Bingo you have a 6 thou feeler gauge.

Thanks, that's good to know. Hope I never have to do this.
