First, I would like to thank @Fastrig for letting me know about the Contessa mounting system. I am wondering if anyone here is using the Contessa QR mount on a Blaser rifle? Or on any other type of rifle. I've done a little research and the price of the Swaro rail mount QR from Contessa is $150 less expensive than the Blaser version. It's also just as secure, repeatable and even quicker to operate. Bad news is that the rail mount version my prove a little hard to get, but I have emailed the company about that. My real question is does the Contessa system significantly raise the rifle scope higher than the Blaser? Anyone out there happen to have both to do a side by side? Would the difference be enough to change your mind on saving $150 per scope base? What about durability vs the Blaser? Any drawbacks I'm not seeing?
