The Ruger-57 Optic Adapter Plate (brand part number 90722) lets you mount a Docter, Meopta, EOTech, Insight, or Noblex red dot sight directly to the slide of a Ruger-57 pistol, and it also fits the TruGlo Tru-Tec Micro TG8100B. Ruger precision CNC machines the plate from 6061-T6 aircraft aluminum and finishes it in a matte black hardcoat for strength and a durable, non-reflective look. Installation is straightforward: place the plate on the slide and secure it with the two provided #6-32 screws, torqued to 30-50 in-lbs with a Torx T-15 wrench (not included), then mount your optic per its own manufacturer instructions.
