Aimpoint ACRO P-1 3.5 MOA 3V

Aimpoint® Acro P-1 (Advanced Compact Reflex Optic)
the smallest closed red dot system on the market.
The ACRO P-1 was specifically designed for use on pistols and weapon systems that require a closed system.
It is the only red dot system of its size that has undergone extensive shock, vibration, and temperature testing. The ACRO C-1 was tested with 20,000 rounds on the slide of a pistol in .40 S&W.
The ACRO P-1 can be used in numerous functions: as a pistol optic, on shotguns, as a back-up sight for scopes, or anywhere a small, lightweight, and robust red dot system makes sense.
