Has anyone tried this new clamp on ati scope mount for their mauser? It looks interesting, but I want to know if if will hold a zero or not before I buy one. Other types of mounts that go on the rear sight base are not an option since it has been removed. The only other option i can see would be drill and tap for normal bases and that will run me at least a $100 dollars. More than i want to spend on my turk. Any suggestions...
