Looks like they're taking a page from Blaser with the cocking device. Like the looks of it.
Manual cocking is now very common in many European rifles offers:
Blaser R93 & R8
Krieghof, blaser,heym & merkel combination guns & kipplaufs
Krieghof semprio
Merkel RX helix
Mauser M03
Heym SR30
Haenel single and double rifles
Steyr Mannlicher SM 12
Pfeifer SR12
Browning Maral
Latest Browning BAR
...
Sauer was one of the last one not offering it.
Sauer, Blaser and Mauser are owedn by the same company.
I checked the review, in addition to the manual cocker, they made a one size fits all action. You may change caliber from 243 to 375 HH, switching barrel + bolt head + magazine.
