just picked up one at a gun show on a whim, all purchases at gun shows are this way). any manuals or pages for the harris bipod to download out there? also, what is that miniature looking keyring thing at the front of the bipod and what does it do? there is also 2 half inch by half inch cylinder shaped clips that are on the top of both legs, that appear to just clip on and off the legs. what are they for and what do they do?
