Get the Acro Advantage. Aimpoint has once again advanced the standard for ultra-compact mounted optics with the introduction of the Acro P-2 red dot sight. This next generation sight incorporates an improved LED emitter coupled with a higher capacity CR2032 battery to provide an astonishing five years (50,000 hours) of constant-on power while getting you on target faster and more accurately. Designed to endure extreme G-forces, the ACRO series was the first ultra-compact sight to offer a fully enclosed optical channel to protect the LED emitter.  Built to exceed the requirements of elite end-users, the Acro P-2 has been tested and proven to withstand the intense shock, vibration, temperatures, and material stresses.
