The new high efficiency LED emitter provides a sharp 3.5 MOA dot. Protective clear glass front and rear lenses guard the advanced reflective lens system. The new digital intensity adjustment keypad provides a more distinct tactile feel when adjusting the dot intensity, and these controls are now placed next to the battery compartment to help protect the power adjustments against unintentional changes. The Acro P-2 can be mounted on carbines, shotguns and rifles or utilized as a backup sight on magnified scopes and thermal imagers. The sight can be mounted on a wide range of optics-ready handguns using adapter plates. It is night vision compatible, and the dot can also be turned up for use in bright sunlight. Aimpoint red dot sights are operationally parallax-free, which means the visible dot remains parallel to the bore of your weapon no matter what angle your eye is in relation to the sight.
