Hi,
Leica sell two versions with different product codes, one measures in metres and the other in yards, so you cannot switch between metric and imperial. Secondly, according to the Leica UK website these binoculars will range up to 1200 metres, if that helps.
I have purchased and received 2 of the above AI mags. I have now tested both mags which fit my AI AT perfectly as well as cycling 10 drill rounds through each magazine on the rifle to ensure they feed correctly. I have attached the two pictures of a magazine texted to me. Hope this helps to clarify the queries ref. compatibility with AI AT and AW rifles.
