Ok but should be much better for $250 - GG&G Extreme Heavy Duty Swivel Bipod

Positives: I like the feet, and I like the rail attachment, really fast and easy. Negatives: The thumb screws that tighten the legs and the mounting point pivot need to be bigger, you can’t get enough tension on them with your fingers to make them hold. I would suggest a detent in the vertical position, to hold better, and because that’s where it would be most commonly used. A heavy rifle will overpower the adjustment screws easily. At half this price I might be able to recommend it.
