And we will also provide you the link to purchase required mounting accessories.

let's take a look

Holosun 507C ACSS - Best Overall

ruger 57 holosun 507c
holosun acss long range shot low light

Why Aim With The ACSS Vulcan Reticle - The ACSS Vulcan reticle has a outer 250 MOA ring that helps the shooter recenter the reticle after each follow up shot.

Easier Slide Racking - The optic provides larger surface area to grip the slide to rack it (Ruger 57's slide is kinda small to be honest for shooters with large hands)

Easier Battery Access - Replace the battery right from the side tray without re-zeroing or sight removal

Super Light Weight - The weight is honestly not noticeable, and it doesn't affect slide cycling performance

Built Like A Tank - Made with 7075 T6 aluminum that matches mil-spec Trijicon RMR level quality to endure rough field use

  • Faster dot recentering
  • Long battery
  • 250 MOA ring is optional (On/Off)
  • Proven durability like an RMR


  • Not many complains

Vortex Venom - Best For The Money

ruger 57 vortex venom red dot sight

Why we pick this one - The Vortex Venom is a rapid target acquisition sight. Overall, the Vortex Venom thin lens frame makes it feel like a large FOV sight.

Wide field of view - Get on target fast, and the thin lens hood frame doesn't obscure the shooter's view

Top-Loading Battery Access - Swap the battery right from the top without removing the whole sight or having to re-zero the sight

What people are saying about it -  Target acquisition is fast along with the bright fiber optic front sight on the Ruger 57 to make a great experience.

Before you order this optic for the first time for your Ruger 57, be sure to get the adapter plate also and we will put the link to the product page at the end of the page

Auto Brightness Control - The sight adjusts automatically to match the environmental conditions to provide a bright reticle for the shooter
