The EOTech EXPS3 Holographic Weapon Sight EXPS3-4 is an exceptional firearm accessory built to aid marksmen who demand precision and durability. This state-of-the-art sight is designed to enhance targeting speed in tactical situations while enabling rapid both-eyes-open sighting at various ranges. The EXPS3's holographic technology is optimized for close to medium-range engagements, offering a unique red ring/quad dot reticle that promotes intuitive and precise aiming.

This model incorporates a 7mm raised quick detach base, providing lower 1/3 co-witness with iron sights and ease of mounting. Once attached, the sight promises steadfast reliability, being submersible to 33 feet and fog-resistant, ensuring clear vision in any environment. Its compact form factor also helps to conserve valuable rail space on your firearm.

Crafted for intense field use, the sight manages power efficiently, running on a single CR123 battery. The extended battery life delivers around 600 hours of runtime on a medium setting, while the sight features 30 intensity levels tailored for diverse lighting conditions – 20 for daytime use and 10 compatible with night vision devices. Adjustments are made effortlessly, with tool-free windage and elevation dials, keeping you zeroed in under any circumstance.


  • RUGGED DESIGN: Built for extreme conditions, the EXPS3 is submersible to 33 feet, fog-resistant, and features quick-detach capabilities.
  • RAPID TARGET ACQUISITION: A 68 MOA ring with four 1 MOA dots allows for both-eyes-open sighting and fast target acquisition.
  • VERSATILE BRIGHTNESS: With 20 daylight and 10 night vision settings, this sight adapts to any lighting environment.
  • EFFICIENT POWER USE: The CR123 battery ensures up to 600 hours of continuous use on medium settings, maximizing time between replacements.
  • PRECISE ADJUSTMENTS: Impact point corrections are easily made with tool-free windage and elevation dials at 1/2 MOA per click.
  • CO-WITNESS CAPABILITY: An integrated 7mm raised base offers lower 1/3 iron sight co-witness for seamless transition between sighting systems.
  • NIGHT VISION COMPATIBLE: Seamlessly work with Gen I/II/III night vision devices with dedicated settings.
  • AUTO SHUT-OFF FEATURE: Helps conserve battery with 8-hour or 4-hour selectable auto shut-off.

Price Match

We guarantee that we offer the best prices online.

If you come across another online retailer that sells the same item from the above manufacturer at a lower price plus shipping cost within one month of purchase, please let us know, and we'll refund the original payment for the difference in price.

For the guarantee to apply, the total order price of the item which includes shipping cost must be lower than what you paid us. For example, let's say you paid a total of $150 for an item on our site. If you see the same item advertised for $140 on another site but shipping cost is an additional $15, the guarantee DOES NOT apply since the total order price is $155.

On the other hand, if the same item is $140 but the shipping cost is an additional $5, the guarantee DOES apply since the total order price is $145 which is lower than what you paid us. The refund amount would be $5 for the difference. Please note we don't factor sales tax into the total order price when considering the guarantee. 

You can email us a link to the product on our website, as well as the link to that same product on our competitor's site within one month from your order date, to request for the partial refund. 

There are a few limitations on our price guarantee:

  • Items must be purchased from our site before requesting the Price Match guarantee
  • Promotions such as rebates and buy one, get one free offers are not eligible
  • The item must be in stock on the competitors website
  • The competitor must only be an online store and not have a physical retail location
  • The lower price cannot be found on an auction or market site like eBay, Amazon, Overstock, Wayfair, Jet, etc.
  • The competitor must be an Authorized Dealer or Retailer of that product
  • The Guarantee includes the total price of the item, but does not include sales tax
