Have a few bipods that I really like that aren't QD. Really didn't think that it was a big deal until I got my hands on an Accutac FC G2. Great bipod but really enjoy the QD part of it. So I've got a Magpul bipod, UTG Big Bore Full Stability bipod, and a harris style which I regularly use on different guns. They have different benefits for each one and use them in different situations. All are picatinny but all have different types of bolts to attach, one hex screw, another 2 screws needing a flat head, and other a large nut. Anyways I looked for a low profile small QD attachment so I can set them up on all them and easily and quickly swap them out. Well I found these from UTG. They make them in both 3 slot and 5 slot lengths. I bought 4 in the 3 slot length. Tried them on my bipods and work great!! Bought 4 of them for the 3 bipods and 1 for my Burris TRS-25 red dot so that's now QD also. Highly recommend them for the price!
