The Ruger 57 has been on the market for quite some time now, and it's getting popularity. However, the gun doesn't come with any optic adapter plates, so I did my own experiment and these are the best Ruger 57 optic plates that I have one by one tested:

Ruger 57 optic plate

The Outerimpact Ruger 57 Modular optic adapter plate allows the user to mount various red dot sights available on the market. There many holes on the adapter plate and holes to place recoil lugs that are designed to lock in the optic's footprint.

These compatible red dot sights include:

  • Trijicon RMR/SRO
  • Docter
  • Insight MRDS
  • Eotech MRDS
  • Leupold Delta Point
  • Leupold Delta Point Pro
  • Vortex Razor
  • Vortex Viper
  • Vortex Venom
  • Vortex Defender CCW
  • Burris Fast Fire 2 & 3 & 4
  • Shield RMS 
  • Holosun 507 ”K”/407 ”K” models require the RMSc plate adapter
  • Holosun 508 ”T
  • UTG Reflex Micro Dot
  • TruGlo Tru-Tec
  • Sig Romeo 3
  • Sig Romeo 3 Max
  • Sig Romeo 3 XL
  • Crimson Trace CTS-1250
  • Springfield Hex Dragonfly – must also use OEM provided spacer plate
  • Bushnell RXS-100 and 250
  • Kahles Helia RD
  • Creative XP Glass Eagle – requires a purchase of M3–0.5 x 10MM screws
  • Noblex NV G
  • SOUSA DARC Micro – requires a purchase of M4 x 8mm Socket Head screws

Simply use the right index posts on the plate that corrospond with the red dot sight's footprint, and you're good to go.
