I recommend the Parts Unknown Borchardt model rear tang sight. It's fully adjustable for angle & mounting screw C-to-C as well as windage & elevation, and the elevation has a neat built-in method of ensuring no slack/lost motion with increasing wear over the years. IMO it's by far the best buy for the money in a serious BPCR sighting system.
