I was able to find a good YouTube video showing the adaption of the Magpul Zhukov-S stock for installing on the Dan Haga adapter (https://youtu.be/GDNs1nbXLWk). I had the tools laid out and it took me about 15 minutes to install. I mounted the stock to the pic rail of my new Ruger PCC 9mm chassis and it works great and s a full folder and makes this breakdown rifle easy to pack away in a backpack. This is a solid adapter for the Magpul Zhukov-S stock as designed. If I would have liked to seen anything different about the mount, I would have liked to seen a lug inside the dovetail to act as a bulkhead for support as the 2 capture bolts are being relied on the grip the pic rail. If that is to difficult to cut into the machine program, maybe a scallop on the outer edge of the adapter would allow for extra land to be able to machine through and allow to place a bolt through the key way of the pic rail to act as bulkhead for support.
