Optics ready plates for Ruger 57

The Ruger 57 is a 5.7x28mm pistol with a factory optics cut on the slide. The cut accepts standard plates for common red dot footprints.

Running a red dot low on the slide means you find the dot quickly and track it through the shot with both eyes open, rather than aligning two iron sights under time pressure. The plate is what turns the Ruger 57 into an optic-ready gun: it fills the mounting interface and presents the exact footprint your red dot needs, so the optic sits flat and stays put under recoil.

Two dimensions have to line up — the cut or rail on the Ruger 57 and the footprint of the optic you intend to run. A few plates include an integrated rear sight to preserve a co-witness backup. Check both against your setup on the individual product page before ordering.
