Evolution of the Holographic Weapon Sight — getting on target faster when seconds count!




When asked which sight to use on an AR15 platform, the EOTech is generally a first choice. It just works so well on the platform, and is truly well suited for police work. There is certainly nothing wrong with a simple red dot system, but the larger reticle with various aiming points simply lends itself to what police officers do. It allows for many reference points at varying distances to compensate for sight offset, without the need to necessarily look for a dot. As a rather staunch adherent to the concept of focusing on the threat and not the sight, this system works really well. When precision is paramount, the center dot can be used. At CQB distances, you need simply put the threat in the correct portion of the reticle and go to work. It has always proven to be very fast, accurate and precise when needed.


The EXPS3-2 takes up little space on the rails, easily accommodating additional accessories such as NVDs or the G23.FTS magnifier.


The mounting system right out of the box co-witnesses most BUIS systems designed for the AR Platform, thus removing the need to buy another mount. It zeroes easily with no special tools and, depending on the model, accommodates night vision equipment as well. In the case of the XPS, mounting that 123 battery transversely really cuts down on the size. For years my preference was the N-battery model for just that reason; it just makes it so compact.

The EXPS3 system is available in two configurations, the only real difference being the reticle. The EXPS3-0 uses the standard 65 MOA reticle with a single 1 MOA aiming dot. The EXPS3-2 uses a 65 MOA reticle but contains two, 1 MOA aiming dots (the sight provided has these two aiming dots). There are some other changes to this system as well. The battery cap and latch are gone, replaced by a simple O-ring and cap tethered to the sight. It also utilizes a quick release system that is shorter, more compact, and goes on and off very easily. Lastly, buttons are mounted to the side in order to accommodate the use of night vision or the three-power magnifier.

The first thing observed was the clarity of the reticle. Not sure if they changed anything, but this one just seemed to be more “solid” to me. There was a bit less of the pixelation that is sometimes seen. It was mounted to my Para USA TTR for the bulk of the live fire testing; but was fitted to several other uppers.

The mount is really easy to get on and off. A simple push of the button in the front of the mount and it comes loose. It fit with no adjustment on all of my upper receivers and the Para USA TTR.
