I have just acquired, in a job lot, a set of Steyr Quick Detachable Sight Mount Rings.

On them are these numbers cast as raised letters on the front turn-off mount of 15.00.07.0007. And the rear turn-ff mount of 22.07.010 and 22.07.014 on the toggle that you pull back to release the mount from the rifle.

They are gloss black and whilst I know they are turn-off mounts from a Steyr Mannlicher. I need to know if they are 1", 26mm or 30mm! And what models?

Help!

Maybe you can contact Steyrarms. They list Steyr mounts on page 11 of their catalogue.

Determining the size should be easy. Just measure the rings with a good set of callipers.

I searched in the document for curiosity, but I did not find anything.
Why don't you write directly to Steyr MANLICHER?

Or here Steyr Mannlicher Au

I have, and had a reply from Steyr USA. Their gunsmith is "out of town" but will address it when he returns.

Maybe somebody at http://www.steyrclub.com/vb/ can help.

I may be missing the point here but can't you just measure the ring diameters ? If you dont possess a vernier just remove one cap and sit it on a 1 inch scope tube, if it fits snug its inch, loose its 26mm. I have similar mounts on my Mannlicher Schnoenauer made by Apel mounting a Pecar 4 x 81 scope, front ring matches objective bell diameter, rear ring is 26mm. Hope this helps.
