The former spec was 40 in lb max. The new spec is 10. I personally torque to 30, using loctite 243. This is my experience and opinion only, and I am not affiliated with any company listed. My preference has been 20 in lb on the light to IWC juncture,  and 30 on the mount itself. Loctite 243 on both. I believe 10 in lb to be too low.

Earl Pittman of IWC has responded to my inquiry regarding this change, as follows:

See instructions #9, a gap is required between halves to allow for the variety of barrel lug diameters Benelli is making in production. 10 maintains enough clamping force.
