I bought a Magpul bipod setup for a 1913 rail back when I had one rifle that needed a bipod and had a rail and now that I have few more rifles that need a bipod the benefits of a quick detach adapter seems more and more beneficial. It looks like LaRue sells such a setup and Midwest Industries sells one and all of the others that I have stumbled across seem to require multiple separate pieces to connect a rail to a rail with a quick connect system. Are these the two options are the market or have I missed some out there. What options have people used in the past and what would you suggest.

If you're using M-LOK, maybe look at KDG Kinect:

*they do say it shouldn't be used for bipods on calibers above 5.56
