The Zeiss 4x32 diasta is a great scope but I had problems mounting it on my mauser m12. I tried mounting with leupold mounts and could not get the scope far enough back to get the eye relief to work. Ended up purchasing a Swarovski Z6 1-6x24, 30mm tube. mounted it in Talley fixed one piece aluminum mounts to keep the rifle light since I hike in long distances sometimes to where I hunt. I looked at a lot of scopes and found the Swaro to be the clearest, crispest optics right out to the edge of the field of view. At 1 power you can have both eyes open and use the rifle like you have iron sights for driven or running game. Every whitetail I have ever shot was running or at least walking. Going up to 4 or 6 power gives you the ability to hunt in more open terrain or stand hunt as well.
