Designed for competitive speed shooting and personal defense, the newest Leupold DeltaPoint Pro model features a large 6 MOA red dot that excels at rapid, close-range target engagement and increases accuracy when it matters most. Its incredibly wide field of view and crystal-clear glass dominate the competition, while its rugged aluminum housing and steel sheath ensure it will perform in the harshest conditions. This extremely versatile sight has an easy-access battery compartment, so you don't have to re-zero after a battery change. It also has click-adjustments for more precision. And this isn't just a pistol sight either; the DP-Pro is ideal for AR's, shotguns, and pretty much anything else that fires a round. Motion Sensor Technology (MST) extends battery life by automatically deactivating illuminated reticles after five minutes of inactivity and then reactivates instantly as soon as movement is detected. Waterproof, Fogproof & shockproof
