Aimpoint has long been recognized as a foremost maker of red-dot sighting systems, but it is only with the recent introduction of the Acro P-1 that the company has expanded this expertise into the sphere of handgun optics. Designed for direct integration onto a semi-automatic pistol slide, the Acro P-1’s enclosed high-strength aluminum housing renders the unit nigh indestructible despite its diminutive dimensions. A non-magnified (1X), parallax-free optic with a 3.5-m.o.a. red dot, the Acro P-1 measures only 1.9"x1.2"x1.2" and weighs just 2.1 ozs., yet is highly resistant to shock, vibration and submersion. Rubberized push buttons on the left side of the housing can be used to adjust the unit’s dot to any of 10 brightness settings, and a compartment on the right side allows the CR1225 battery to be replaced without unmounting the sight. us.aimpoint.com
