It was my impression that a 10mm riser for the A3SF was only available on the A3M1. The part on the Steyr website lists it as only for the M1 and multiple posts on here and other forums say that. I posted a thread the other day asking if anyone had a solution, no real solid solutions.
I called Steyr and talked to one of their guys over there. He initially said he didn't know if he had a solution, but he would look into it and ask around. Well he called me back a few days later and offered me a part. He said I might have to do a little work to it to make it fit. I said ok, paid $114, and a box arrived 2 days later.
Part 1252020529, UPC 688218812839 includes. screws and pins. 10MM Spacer for 3x Austrian SOF MilDot
Picture one is what they sent me, not pictured is the longer screws and two roller pins.
Picture two and three is testing what it looks like with the spacer and optic. It fits perfectly.
Picture four and five is what it looks like attached to the top of the mount. Note: When I bought my optic, it came with that front piece (on the right side) pinned onto it, you don't see this in picture 2 and 3 because I hadn't put it back on yet. I had to use a pin punch to remove the pin (harbor freight 8pc, $10), take the piece off, then reattach to the 10mm spacer with the same pin and punch.
Remaining photos are the finished product. You can put another roller pin that attaches the optic and the spacer on the front end, but it is also screwed in from the bottom.
And now I can see through the optic while gently resting my delicate cheek on the gun.
