America's favorite rifle scope just got better. The VX-3i brings legendary Leupold® Gold Ring performance to a new level. Like all VX-3i Series Scopes, the VX-3i CDS-ZL features the Twilight Max Light Management System, which eliminates 80% more glare-producing stray light than competitors, adding up to 10 extra minutes of shooting light to the end of each day. But the CDS-ZL (Custom Dial System Zero Lock) model provides 14.5 MOA of bullet drop, which equals 500 to 700 yards of travel for most rifles. The push-button Zero Lock system eliminates accidental dial movements and provides simple return to zero. And side focus parallax adjustments are fast and easy from any shooting position.
