Yes, this would work for that setup. You would need one of the 30mm models.
Unfortunately his product will not work with the Sadlak mount. The QD levers will not close based on the height of the levers (which protrude just below the bottom of the base) in conjunction with the short distance between the top of the picatinny rail and the top of the Sadlak mounting plate on which the rail sits. Now you could reverse it and put the levers on the right side of the rifle, but ain't nobody got time for a -20 moa cant!
