Thank you Sir....I knew that you would have the scoop (as always)njsfm15, There's only one part that is unique to a Mannlicher stock and that is the forend cap (stainless steel or blued). The rest of the gun (blued or stainless) is identical to a carbine. So ... if you happen to run into a Mannlicher stock with the forend cap, it's a simple drop-in! The older Mannlicher stocks had a front sling loop like the one in my picture. I think they just put a front sling stud on the newer models.
