What? Maybe you should expand on your topic/subject. Not much we can work with. After all, you put two letters in you topic. I have only good to say about Harris bipods. I own one and it is strong as a bull. In fact, I just had it break a cast-iron shooting rest two days ago. Had a Harris on my rifle, went to shoot from the rest bolted to the bench, so I folded the bipod up and put the back of the folded bipod against the front of the rest. Bamm. The recoil put the Harris right through the rest. The Harris wasnt even phased, but the cast-iron rest looks like it just became scrap metal.
