For what it’s worth I make pic rails for Kimbers. If you wanted it built as a two piece, I’d be happy omit the middle section...
Regarding tallys, there are many many out there and lots of guys have had good experience with them (one of my rifles is currently wearing a set). That doesn’t refute the fact that failures like this can and do happen. There is no possible explanation beyond a catastrophic material failure here. If that mount was made of a quality grade aluminum, an over torqued screw would only be capable of three things: stripping its own threads, popping its head off or stripping the threads in the receiver. If none of the above things happened a screw head of this size could be sucked right through a mount made of half decent aluminum without splitting the mount.
