Do you know how much the adapter would be for the Saker to fit on a 51T mount?
As far as I know, it's the same price as the Trifecta mount, and you can order the Saker with the 51T mount instead of the Trifecta. You have your choice of mounts when you order, but so far it's just the Trifecta, 51T, and threaded version. So depending on your definition, it doesn't really cost anything to get the 51T mount, although the threaded version costs less.
Thanks for the review GoingQuiet, I'm really looking forward to getting mine in another 6 months or so. Still waiting on the Form 3 to my local dealer. I can't wait!!!
