A.R.M.S.® #19? Throw Lever® Mount NSN 1005-01-469-7050 > ARMS | ARMS
This is the mount I use for my Hensoldt scope, the holes on either end of the mount are the same as on the claw mounts. So you just unscrew the scope from the claw mount and use the same hardware to screw it onto the ARMS mount. There shouldn't be any clearance issues with the rear sight either, though I'm not 100% on that without testing it myself.
