My first harris bipod had friction legs. I ended up buying another one with the notches and move it around enough I'm looking to by another one. I'm sure someone out there likes the friction legs, but I find the notched legs faster and easier to adjust. Its a one had operation verses using both and wrestling the bipod with the friction legs. Both of mine are 9-13 and I almost never have it adjusted all the way down. As mentioned above, the 6-9 is designated for benchrest on their web page.
