Adjustable Rear Aperture Threads

I am looking for an adjustable rear aperture with 3/8'-24 male threads. Does anyone make such?
Failing that, what is the "standard" threading for Anshutz, Gehmann, etc.?

Have you looked in their catalogues ? Gehman etc should have the details contained therein.

Good luck with that.
It is M9.5x1, and it did start out as a British bicycle thread that might have been 3/8" x 26 at one point, and then it got metricized. I looked for a tap, but not even Brownell's carries it. Easiest was to get a M10x1 and have it custom ground.
The other option was to get a Chinese tap manufacturer, and order 100 of them. I thought about it, but decided against the distraction of trying to sell taps. I imagine Brownell's would buy them from you if you could supply them.

taps and dies can be found by looking outside the shooting world.
they are used in the model steam train and static engine world.
not sure where you would get them in the US but i got mine from a specialist model engineering supplies store here in the UK. If i remember the name i'll post it up here.
