The EoTech Model 517 HOLOgraphic Weapon Sight has been designed and tested to provide consistent, reliable performance, even in the most hostile operating environments. The gun sight's full-view, heads-up display allows for engagement with both eyes open.

  • Holography allows for operation when window is obstructed by mud, snow, rain, etc., remaining fully operational, with point of aim/ impact maintained
  • Sight is fully functional and zero is maintained even if the front window is shattered
  • Waterproof (submersible to 10 feet), fog-proof, shock-proof, and withstands extreme temperature variations
  • Meets military drop test requirements with no functional degradation

  • So Sweet!
    Verified Purchase

    Installed with an EOTech G33 magnifier. All fits perfectly on the rail. Easy installment with the side screw, and it's great to have the buttons on the side when using a magnifier. Sits at the increased 7mm height. It does not interfere with the flip-up iron sights. WONDERFUL PRODUCT!

    The 517 is easy to mount and use with the side adjustment buttons. Great to adjust without taking your eyes off your target or obscuring your view. Best price I could fined and I looked everywhere! EoTech-how can you go wrong.

  • Excellent product and high quality
    Verified Purchase

    As most people know already, the EoTech HOLOgraphic sight is an excellent piece of equipment to add onto a varity of weapon systems. Only needed minor adjustment needed to windage and elevation before tearing out the bullseye of a target at 50 yards. Well worth every penny spent.
