I have sent SA Machine multiple emails about his Uzi Nut barrels over the past year and he never responded.
At this point I wouldn't give him any money even if he did eventually respond. If this is how he treats folks trying to give him money, I can only imagine what it will be like once he has my funds.
In terms of the OPs question, I am not sure who else makes a rail mount for the SW76/MK760. That said I dont know how handy you are but if you have a some basic skillset I would grab a 1.5" billet clamp off of eBay or one of the automotive roll cage vendors and it should be pretty straight forward to cut it up and mount a small red dot on it.
Grab something like this
eBay item number: 231553054320
Cut a clearance out of the curved bottom portion where the trigger frame would protrude and then drill and tap two hole on the flat upper section of the clamp to direct mount a fastfire, RMR, etc. directly to the flat top surface.
Good luck
