When used in Close Quarters Battle (CQB) environments, this revolutionary weapon optic delivers amazing speed and accuracy gains, uncompromising use of peripheral vision, leaves no muzzle-side optical signature and is packaged in a compact, durable unit. Now deployed with elite Special Forces and SWAT teams the world over, the HWS delivers vastly improved shooting performance for all levels of operators.
The EOTech 517 is the non-night vision version of 557, except that it does not feature the .223 ballistic reticle. Rather, this model HWS comes with a standard reticle - 65 MOA ring with alignment ticks and a 1 MOA aiming dot. The large, open ring is the key to the lightning quick eye recognition and unmatched target acquisition speed. Alternately, the 1 MOA can be used for precision aiming at distances as far as 500 yards where it only covers 5" of the target scene. The reticle demonstrates its versatility for a host of close quarter and long range engagement scenarios.
The buttons have been moved from the back to the left side for instant access, allowing a Eotech magnifier or a back up iron sight to fit closely to the Sight body. This new button position allows the user to operate the HWS function switches easier than ever before.
The EOTech Holosight can interface to any standard issue M16 or M4 variant in either a fixed carry handle or flattop receiver, and with no modifications to the weapon. The M16 and M4 mounting platforms provide for the functionally critical aspect of co-witnessing the iron sights within the HWS's Heads Up Display while maintaining the operator's critical check weld position.
The 517 Eotech Sight has been designed and tested to provide consistent, reliable performance, even in the most hostile operating environments. This HWS is waterproof (submersible to 10 feet depth), fogproof, shockproof, and withstands extreme temperature variations.
