According to my Sako Finland info/schematics, The L461 and A1 use: W22x1/16", (guessing W22 is meant to be M22 but if it is I wonder why they have "W" referenced at two different locations....) Pitch 1"/16, Pitch Dia. 20.946 +0.10, Thread angle 55 degrees (not 60 degree). S491, M591 and L691 are identified in schematic as: 1"-16UN Form Special B; noting the words "Form Special B (also applied to the Sako L61R, AIII , AIV, and AV)" .
