Steiner optimized the 1-4x24 P4Xi Riflescope for patrol rifles and AR platforms and designed the optical system with true 1x imaging (for aiming with both eyes open), high-contrast optics, and an illuminated reticle, each of which will add stealth and precision to your CQC operations. While the high-contrast optics will provide you with vivid images during the day, at night they are designed to improve target recognition and visibility. The P3TR reticle reticle is calibrated for 5.56 and 7.62 rounds, with stadia allowing you to confidently shoot to 600 yards. Eleven brightness levels offer optimized settings for almost any situation: 5 for daylight, 4 for low light, and 2 for use with night vision devices. The scope is parallax-free at 100 yards. To assist you in compensating for wind and ballistics, the scope has a 100 MOA windage and elevation adjustment ranges with 1/2 MOA intervals.
