I am using four M-98 action rifles with left handed scope safeties, for my wildcat test beds. I found that using Mark X cocking pieces made for their non adjustable triggers, will let you pass a small mini screwdriver blade through the small hole in the saddle of the cocking piece. This way you can disassemble the bolt without the old Mauser three position wing safety standing straight up.

When the bolt is closed and cocked, this hole is behind the rear of the military shroud. Mark X used the F.N. streamlined shrouds, with a corresponding hole through its sides, but this leaves their side safety on the wrong side, of these rifles, for us lefties.
