Quality scope mount - Nikon M-Series 30mm Optics Mount

While I have yet to subject it to much abuse, and hope I never do, it appears to be a high quality mount. The scope attaches with only 2 screws, versus 4 for other mounts, so it attaches to the scope more easily. The 1 piece design allows for greater ease in removing and adjusting scope position on the rifle. I mounted a 50 mm objective scope on a Remington Model 597, and it provided ample clearance.
