<p>Perfect for pistols, the Aimpoint® Acro™ P-2 Red Dot Reflex Sight is a low-profile red dot with a crisp 3.5 MOA dot. Submersible to 115', this red dot sight is tough enough to handle whatever you throw at it, and with its improved LED emitter and easily replaceable CR2032 battery (included) that delivers up to a 50,000-hour lifespan, you can depend on this sight to be ready whenever you need it. An enclosed optical channel protects the emitter, and the 7075-T6 hard-anodized aluminum construction is built to withstand shock, vibration, temperature, and stress as tested by more than 20,000 rounds of .40-cal. ammunition. The clear glass lenses both front and rear protect the reflective lens system, while a digital intensity adjustment keypad cycles easily through 4 night-vision settings and 6 daylight settings. This parallax-free sight can be mounted on a wide range of optics-ready weapons with a variety of mounting options (not included). 1.9L x 1.3W x 1.2H.
