Caldwell Accumax Carbon Fiber Bipod
These lightweight bipods are the latest from Caldwell. I have tested them myself and they work really well and are so much lighter than a traditional Harris bipod. It features quick-deployment carbon fiber legs with 90 degree forward locking method or backward method with spring-loaded buttons. The Premium Carbon Fiber Bipod also features an omni-directional ball mount for 360 degree panning, a lever lock handle for fast adjustments, and of course, twist-lock leg length adjustments.
Note the attachment to the sling swivel is very sturdy but you need to read the instructions on how to fit it, when you do it will be simple.
