Skip this and buy a reliable brand such as YHM.The picture is inaccurate. On the part I received, the post (sling attachment point) does not sit at the proper height, it protrudes a full 1/2" above the surface. The harris bipod is incapable of taking up that much slack so the bipod cannot be secured to the adapter. This is not a defect in manufacturing, it is a defective design. Take a close look at the other reviews and you'll see that this is a common problem for about 1/3 or more of the items shipped. Why not all? Not sure. I bought this from GRG MFG but it also ships from Combat Optical. Is it the dealer or the manufacturer? Not sure who's to blame, but someone is defrauding us.NOTE: I mentioned YHM only because that is what I bought to replace this adapter. The YHM has much better fit and finish, it's solid, and it's simple to install, but it did cost about $16. I am not associated with YHM in any way.
