For one of the best weapon sighting systems available for purchase today, consider the Model 518 Holographic Weapon Sight (HWS) by EOTech. Because this innovative device operates on easy-to-find standard AA batteries, making battery replacements is a breeze.
EOTech has been the #1 manufacturer of holographic weapon sights since 1996, when the first-generation holographic sight was released to the public. The second-generation sight was introduced in January of 2000. The company continues to produce quality weapon sights to this day for both military and civilian use.
Holographic weapon sights have an advantage over iron and telescopic sights in that they permit the user to keep both eyes open during target acquisition. The ability to maintain full peripheral vision when taking aim allows greater situational awareness and increased depth perception. These are advantages that cannot be overstated during CQB situations or when dealing with fast-moving targets (think wild pigs, feral dogs and criminals).
The Model 518 holographic weapon sight features side button operation to reduce rail space and can be used in conjunction with an EOTech magnifier. The weapon sight is water-resistant to 10 meters and will attach securely to all Mil-Spec 1913 Picatinny rails or 1” Weaver rails.
