The EOTECH EXPS3-4 combines holographic sight technology with a 68 MOA Speed Ring and four vertically aligned aiming dots. Its rectangular viewing window supports both eyes open operation, while the multi point reticle provides additional aiming references for compatible 5.56 NATO and .223 Cal. setups.

4 Dot Speed Ring Reticle

The reticle combines a large 68 MOA outer ring with four aiming dots. EOTECH optimizes this pattern for 5.56 NATO and .223 Cal. platforms using specified 62 grain M855 munition at approximately 2,680 feet per second from a 14.5 inch barrel. The individual aiming dots may be easier to distinguish when the sight is paired with a compatible magnifier.

Daylight and Night Vision Settings

Twenty daylight brightness settings support changing ambient light, while 10 additional settings provide compatibility with Gen I through III plus NV devices. Side mounted buttons remain accessible when a compatible EOTECH magnifier is positioned behind the sight.

Raised Quick Detach Base

The integrated quick detach base attaches to 1-inch Weaver or MIL-STD-1913 rails and raises the sight by 7 mm for lower one third iron sight co witness. One CR123 battery provides approximately 1,000 continuous hours at nominal setting 12. The housing is water resistant to a depth of 33 feet and operates from -40 to 140 degrees Fahrenheit.
