I have used Harris Bipods for years and they work good but one design problem exists. They have springs in the legs that return the leg, when yur trying to level your rifle on uneven ground you have to hold your rifle with one hand and unscrew the lock ring and pull leg out and hold it while you turn the lock ring with the other. Seems to make more sense to me to have compression springs springs to extend the legs. I looked to see if this has been discussed before but couldn't find anything. My question is does anyone make a bipod like this?
