The VX-Freedom RDS (red dot sight) changes the game when it comes to consistency and durability. It features Leupold's Twilight Red Dot System with standard color consistency and premium lens clarity. It delivers a clear and precise aiming point with 1 MOA dot, and offers 1/4 MOA click adjustments. The VX-Freedom RDS also utilizes a push button illumination, Motion Sensor Technology (MST), and an AR-height mount. The CDS Bullet Drop Compensation (BDC) elevation dial, calibrated for .223 Remington 55 gr. ammunition, provides measurements out to 600 yards.
