The Eotech 557 Multi Purpose Optic 4X FXD is Eotech's latest in its line of innovative, performance driven products designed to aid the modern day warfighter.

Notice: The 557 range is now only available to police and military agencies providing legal procurement documentation. They cannot be purchased over the intermet. Please call to discuss this item further.  

The EOtech MPO provides a complete optical system that solves the need for medium range precision targeting and target identification, as well as rapid transition to close quarters battle (CQB) engagements where speed and peripheral vision are essential.

The EOTech MPO Holographic Sight is configured with a new ballistic matching reticle image for the M4 carbine. The reticle provides 4 aiming dots for target distances of 0-300m, 400m, 500m, and 600m. When viewed without magnification, the 65 MOA circle and fine center 1 MOA aiming dot are used, ensuring precision accuracy. Only through the unique optical properties of holography, the aiming dots remain 1MOA in size, regardless of magnification (yet your target has increased in size by nearly 4x)! Precise, medium range targeting (out to 600m) can now be achieved.

Field of view is optimized by integrating high quality prisms that maintain the rectangular shaped sight picture of the EOTech HWS, and since the illuminated reticle image is imbedded within the HWS, there is no risk of losing zero when the magnifier element is taken off or re-attached. Additionally, the base of the EOTech 557 HWS has been modified to reduce the amount of rail space required to effectively mount the system, making this ideal for the M4/AR15 flat-top platform.

For the infantryman, target ranges vary in ever-changing battlefield conditions. L-3 EOTech MPO Weapon Sight provides a solution for engaging threats in CQB situations, then quickly transitioning to a 500m targeting or surveillance situation, and then quickly back to a 25m room clearing exercise. Instant transition is achieved through a quick Flip-to-Side (FTS) mount or optional fixed mount (FXD) that offers a simple, quick disconnect feature to remove the L-3 EOTech 4X magnifier. This EOTech durable, night vision compatible system offers wide field optical performance with superior light transmission for visibility in extreme low light conditions.
