Wanted: Sling stud mount folding rifle monopod

I want a monopod to support the rear of my rifle stock on my long range precision build. It needs to be a folding type that mounts to a sling stud, preferably something akin to an accushot BT04-QK. Ideally with a locking dial to secure the height setting. Also, it should be able to be set longer than 4-3/8" as well as shorter to give range of height on both sides of level.
