The DeltaPoint Pro is proof that you don't have to compromise performance, even on a small sight. Its incredibly wide field-of-view and crystal-clear glass dominates the competition, while its rugged aluminum housing and steel sheath ensure it will perform in the harshest conditions. Ease-of-use was also a focus when designing this elite red dot sight, which is why we put an easy access battery compartment on top and gave it click-adjustments for more precision. And this isn't just as a pistol sight either; the DP Pro is just at home on AR's, shotguns, and pretty much anything else that goes bang.
