So of all the Chinese devices the base rings seem to be a standard 40,45,50 mm option. For me the 50 is too big and the 45 is close but a little too tight. Has anyone ever found somewhere to get a base ring in-between 2 sizes? I'm thinking a 47-48 would probably fit me just right. Thank you
well you cud ask the folks that make them or it migt work giving one a bash with a hammer. but dont miss and hit your finger.
I have taken a 50mm and squeezed it into an oval shape but then it opens up the seam at the top of the ring and pinches. Still doesn't make up for the ring being too big.
