OK smart, now you've gone and done it!!! I'm gonna have to underfold my S12. I'm in the middle of taking 2 of my M70 underfolders and making one a fixed stock, and swapping the underfolder from that one (stamped) over to my milled M70 underfolder, which leaves me an extra folder and trunnion. Was thinking of selling it, but now I think I'm gonna put it on my S12. Gotta get a pad of some sort though. That thing kicks like a mule!!!
Great job on the S20. Keep the pics coming.
