It looks to be mostly suited to the sitting position.
If It were me I'd want a free standing monopod on the back end.
With the rear support being anchored to one of the legs of the tripod instead of directly to the ground it's building in some flex/instability on both ends.
There are a ton of different fully adjustable rifle monopods on the market already and so again if it were me that's the way I'd go vs this type of set up.
