I got my SoLow mounts about 6 months ago. I had to file the bottoms of the the legs a little bit because they put a bind on the receiver after they were tightened. It wasn't very difficult, just took a little bit of time. I didn't use the epoxy and they seem to stay put. But the SoLow rings scratched my red dot, apparently there was a burr around the edge of one of them. Have fun !
