Why would you want to shoot upside down?
Thanks for the info hjk_rik! I had suspected that that was the case, as I have heard both accounts, but only know of my own experiences with my MKII. Any idea if it is possible to get a bolt retrofit for the slightly older MkII's like mine. I grew up using an M94 Swede Mauser and was used to controlled feed till I bought the MkII as my first deer rifle.
