Set screw spacing seems to be approximately .450", but I would highly recommend reaching out to Odin Works to get the exact dimension from the manufacturer of the part.

It did fit my pre dimpled barrel. Usually dimples in barrel are straight across from the gas port hole and gas block are usually manufactured with the set screw inline with the gas hole.
