The EFLX(TM) is EOTECH's first venture into reflex technology optics. Designed for pistol use, the base is configured to the LeupoldA(R) Delta Point Pro(TM) footprint and will adapt to appropriately milled slides or onto a rear dovetail mounting adapter. Its durable, heavy duty aluminum housing provides a large, square viewing window, that maintains the same aspect ratio as EOTECH's HWS, to make the 6 MOA aiming dot easy and quick to find. A top load, single 2032 battery provides roughly 20,000 hours of run time. Ideal for professional use to get you on target fast; law enforcement, hunting, home defense, and more, the EFLX can be used on a variety of pistol platforms. In addition to being the ideal solution for a pistol red dot sight, the EFLX can be used as a 1X solution on shotguns or rifles with magnified optics.
