as above. these are 30mm blued in good overall condition apart from some of the screws look a little past there best so will prob need replacing. with the better torx head ones you can get now.
i am not sure on the height of the rings. but the guy i had rifle off had a 50 mm obj leupold scope on this m695 sporter barrel and that fitted snug above the barrel.
£55 posted for the rings and bases due to the some of the little screws need replacing.
