The footprint has four screws - two in the front and two in the rear. The holes on the left are detached from the ones on the right with a raised part in the middle.
Vector Optics Centurion 1×30 features a modified Trijicon MRO footprint. The spaces between the screw holes are identical, as well as the thread. The distinction appears in the raised section. On Centurion, the middle part of the raised section is cut out in order to make space for a recoil stop. In consequence, a mount created for the Trijicon MRO footprint fits on the Centurion, while the one created for the Vector Optics Centurion (with a recoil stop) does is not suitable for the MRO, as the middle part of the raised section is not cut out.
