Best Red Dot Sights For FN 57 [Currently Compatible]
Top 3 Options
Holosun 507C ACSS - Fastest Target Re-Acquisition
Why Use ACSS Vulcan Reticle - The ACSS Vulcan reticle helps the shooter re-center the reticle after each follow up shot. The 250 MOA outer ring re-centers the eye to realign the optic
Easier Battery Access - Replace the battery right from the side tray without re-zeroing or sight removal
Uses RMR Footprint - Same footprint as the Trijicon RMR
Bigger Buttons - Enlarged adjustment buttons for better reach for shooters with big fingers
Super Light Weight - No weight difference from the the original 507C X2. It's light for carry
Built Like A Tank - Charge the slide against the optic without any issue
- Faster dot recentering
- Long battery
- 250 MOA ring is optional (On/Off)
- Proven durability like an RMR
- Not many complains
Leupold DeltaPoint Pro - Best Lens Protection
The Leupold DeltaPoint Pro is a classic red dot to go with the FN FIVE SEVEN MRD. It has similar FOV size as the Trijicon SRO, and it features extra layers of hood protection to divert impact stress away from the glass when the gun is accidently drop on the optic.
New 6 MOA Available - 6 MOA is much more crisp and rounder to see than a 3 MOA for shooters with astigmatism
Extra Housing Protection - The added lens hood protects the optic from receiving direct impact that increases durability and making it fail proof.
Top Battery Access - Load/Replace battery right from the top!
- Big rectangular glass FOV
- Durable lens hood
- 6 MOA now available
- Short battery life
- Adjustment button is in an awkward spot
Trijicon SRO - Large Circular FOV
Why we picked this one - Trijicon SRO is exactly the same as the original RMR but with a bigger circular shape FOV for faster sight acquisition for the FN FIVE SEVEN MRD.
Better Follow Up - Increased sight acquisition speed without losing the dot inside the window.
Bigger Window - Re-acquire the sight picture faster after each follow-up shot even if the sight picture is slightly off center.
Easier Battery Access - Load/Replace battery right from the top! No sight removal or re-zero required
- Big FOV
- Very slick looking
- Great for competition use
- Not duty grade lens construction
Trijicon RMR - Best Durability
The Trijicon RMR is the predecessor of the SRO. This is the gold standard red dot sight for pistol use, and many users choose this one for duty carry and range use.
The ruggedized lens frame diverts impact stress away from the glass much better than the Trijicon SRO's thin circular glass frame, and thus it's a much better choice for duty carry.
Besides that, the RMR is an open emitter red dot sight with plenty of dot sizes to choose from. 6 MOA is our favorite for pistol use.
