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

Leupold DeltaPoint Pro - Best Lens Protection

FN 57 mrd deltapoint pro

The 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
