Wasn't sure where to post this... Looking to buy another bipod for prone shooting. The one I have now is a 6-9" Harris bipod w/ swivel & adjustable legs w/ notches in them. I used a buddies last week & he had small screws that you could loosen/tighten to adjust the legs (no notices) but you could set to any height between 6-9". What kind do y'all prefer?
