The Ruger 57's slide is milled on top to accept optic adapter plates, and our favorite is the Trijicon SRO and Holosun 507C. However, currently the Ruger 57 isn't compatible with these two optics yet, and all we need is for the aftermarket community to release an adapter plate for them.

Since the 5.7X28mm is a soft recoil round, any reflex sights on the market would work as long as you have the right adapter plates installed on the slide.

So in this guide, we will review some of these currently compatible sights you can use without costing your entire monthly living expenses.

Vortex Venom

Ruger 57 with vortex venom red dot

Why we pick this one - The Vortex Venom is a 3 MOA rapid target acquisition reflex sight made with aluminum housing that is durable for range use, and it's compatible with the Ruger 57 using the Vortex optic plate.

This sight is very similar to the Burris FastFire 3 which we will talk about in the next section, and it features a Leupold DeltaPoint Pro alike wide field of view with automatic brightness mode that uses an ambient light sensor to control the dot intensity, which is helpful under constantly changing light condition.

The top-loading CR1632 battery access makes battery swap extremely easy without removing the whole sight like others available on the market.

What people are saying about it - Overall, the Vortex Venom is a fairly large FOV sight without breaking the bank for just under $250. Target acquisition is fast along with the bright fiber optic front sight that makes shooting the Ruger 57 an amazing experience.

The optic is ultra lightweight and low profile design makes it a very pleasant optic get fast on target on pistol caliber and rimfire firearms.

For 5.7X28mm plinkers out there, this is the best micro reflex red dot for the money for anyone starting out new or for experienced shooters.


What people are saying about it - The Burris FastFire 3 is a very affordable reflex optic for competition guns as primary optic or offset optic, it's lightweight and features a very long lasting battery design up to 5 years with the automatic time-out feature.

Besides its obvious unlimited eye relief red dot aiming capability, the dot brightness can be easily adjusted to match the environmental conditions so there is no need to manual adjust the brightness when transiting in and out of dark and low light areas.

For high-velocity 5.7X28mm - The 3 MOA dot is most popular with rifles, or anyone wanting more pin-point accuracy, as the smaller dot covers far less of the overall target area.
