I have a Harris bipod that is for prone and one that goes from 13-24" and it seems like I never have the right one on the rifle at the right time. If the grass is very high, the prone one is too short. If the grass is short, the 13" is too high for prone sometimes without raising my body off of the ground. Then one of my rifles has a 27" #7 contour barrel with just one swivel on the forearm so when you mount the bipod and hook the sling onto the bipod the rifle wants to tip upside down! All of this has me thinking that maybe I should switch systems. What does anybody use that will allow a range of adjustment from say 9" to 24" or am I stuck carrying both of my bipods? Thanks. Tom
