DUGABOY1 It is all armchair engineering until you can pull them apart, print them and do some analysis isn't it?

I guess all I'll say about the Krieghoff is that I was surprised at how compact it is for caliber (to me anyway). I'm a little surprised that the fact it only has one fastener hasn't come up either.

Edit: I guess the little nub between the barrels acts like a dolls head to help resist twisting.
