16.5" Red Dot Artar thread sizes

[henrysamson]

Hi,

Does anyone know the front and/or rear thread sizes for a 16.5" Red Dot Artar. I am trying to get step up rings, hoods and caps. I realize they might not be standard or even the same across the entire production life but any info will be appreciated.

Thanks!

They aren't standard and you will not find standard step up rings. Hoods and caps should be a standard "Series" size.

There are lots of related threads:

The threads do not have a standard pitch, therefore you can't find a normal step up ring that will fit. You will need to have one custom made. S. K. Grimes can do the job for you.
