It is unlikely the MG08/15 was bought by Austria Hungary; I've seen no photo evidence, or documentaion to suggest it had.
AS you likely know, the KuK used the Schwarzlose MG. It was comparitively light when compared to a Vickers, or Maxim. Additionally, though the system was designed to utilize a tri-pod( the configuration most often seen with the weapon) it was supplied with a shoulder stock extention that could be bolted to the receiver. The carrying back-pack for the gun was fitted centrally with a steel sleeve to accept the gun's pinion, and in demands of expediency, could be utilized as a extemperized block mount for firing.
After the success of the MG08/15 was noted, a bipod was developed to clamp over the foward portion of the water jacket; which, when utilized with the shoulder stock, made the Schwarzlose a reasonably successful assault weapon.
