Not sure if anyone has posted on these yet but I recently found them and they’ve been one of the better investments I’ve made upgrading my setup. The factory die blocks from FA have been terrible for me and rarely ever hold dies in place, and even using aftermarket retaining screws barely made a difference. These die blocks have a two retaining screws on a c clamp style block so they grip the entire die much more efficiently than the FA die blocks do only having a single point of contact with the die. The metal is a lot tougher than the FA blocks so the set screw that holds the die in the press doesnt shred the block itself. He ships from Australia and I think my 3 die set was about $100 including shipping.
