    Holosun EPS Full Size Reticles

    The Holosun EPS Full Size comes in red or green reticle versions. It also has the option to choose a 2 MOA version, 6 MOA version, or the MRS version. The MRS version features a solar panel, which make it one of the only options in this size to have a solar panel. The solar panel gives it auto brightness modes (in addition to manual) and the solar failsafe feature.

    The MRS Reticle is three reticles in one. You get a 32 MOA outer ring, a 2 MOA Center dot, and can use just the 32 MOA ring only.

    To toggle the reticle, you hold down the "-" button for three seconds and the reticle will change.

    The MRS reticle is nice if you want flexibility. The larger outer ring helps you "find the dot" and the 2 MOA center dot is small and precise.

    The green reticle versions are slightly more expensive than their red dot counterpart.

    The Holosun EPS Full Size comes with an RMR adapter plate. This means it will fit on any RMR footprint slide or adapter plate.

    *Note: The EPS Full Size RMR adapter plate will not work with any "Zev Post" slides. Also if you plan on using a "plate sandwich" where you mount the RMR plate to another plate for your gun, you may run into screw length issues. Refer to the fitment table below for more information.

    Holosun EPS Full Size Intended Use

    The EPS Full Size is a K series footprint optic but comes with an RMR adapter plate and is a regular sized pistol red dot. This means it is intended for use on any pistol with an RMR footprint or RMR adapter plate. Most of the time this means the pistol will be a full size or compact such as a Glock 19 MOS or a S&W M&P 2.0.

    Make sure you know what footprint your gun is. The EPS Full Size is not intended for and usually will not fit any micro compact pistol like a Glock 43X MOS or Sig P365 without getting special screws or adapter plates. For the smaller pistols you want to look at the EPS Carry.

    The EPS Full Size can also be used as a rifle optic, PCC optic, or backup scope optic if you get a "K Series" picatinny or offset adapter found here.

    When you open the Holosun EPS Full Size this is what you will find in the box:

    • 1x CR1620 Battery¬†(installed inside the optic)
    • Holosun Warranty Card

    Holosun EPS Full Size Review & Highlights

    The Holosun EPS Full Size is a great do-it-all enclosed emitter optic. If you aren’t familiar with enclosed emitter optics you can learn more in our open vs closed emitter optic guide here, but the gist of it is that an enclosed emitter optic fully protects and covers the laser emitter. This means nothing can get in the way of the laser such as dirt, dust, debris, or precipitation.

    For those who want the ultimate peace of mind in reliability an enclosed emitter optic will provide that.

    Open vs Closed Emitter Pistol Red Dot Diagram

    The Holosun EPS Full Size is a great package. It has a low deck height, nice sized window, comes in a variety of reticles and price points, it’s built very sturdily and has just about every feature Holosun provides in their pistol optics.

    You can get it in red or green reticles and it comes in a 2 MOA dot, 6 MOA dot, or the MRS reticle which is the 32 MOA outer ring, and 2 MOA center dot which can be toggled to use the 2 MOA dot only, 32 MOA outer ring only, or both together by holding down the ‚Äú-‚ÄĚ button for 3 seconds. The MRS version comes with a solar failsafe and additional auto brightness feature.

    It‚Äôs important to note that the footprint of the EPS Full Size is a ‚ÄúK Series‚ÄĚ and that it comes with an RMR adapter plate. This can make mounting a bit tricky so make sure you know exactly how you would fit it on your gun. Most times the RMR adapter plate works fine, especially if you have a dedicated RMR cut slide, however if your pistol comes with a multi adapter plate system and you stack the RMR adapter plate on top of that, sometimes you can run into issues with screw length or thread pattern.

    If you have a platform that requires you to stack multiple plates (which we call a plate sandwich) we recommend getting a ‚ÄúK Series‚ÄĚ adapter plate if available so you can use just one plate. You can find the proper adapter plate for your platform here.

    Also it is very important to note that if you have ‚ÄúZev Screw Posts‚ÄĚ, like the Bul Armory Axe or Zev RMR Cut slides the EPS Full Size will not work because the adapter plate will not be compatible with the screw posts.

    The EPS Full Size has all of Holosuns best features like shake awake, side removable battery, IPX8 waterproof rating, long battery life, manual brightness, and on the MRS versions it also has the solar failsafe and auto brightness.

    Holosun EPS Full Size Downsides

    The only downside to the Holosun EPS Full Size is its footprint. If it was a dedicated RMR footprint it would be a little easier to install. However we know making an RMR footprint enclosed emitter optic is extremely difficult because there isn't a good place to put the screws.

    This is why the Holosun engineers used the K series footprint + the RMR adapter plate.

    The good thing is that the RMR adapter plate works great in most scenarios, and there is a lot of aftermarket support of people making dedicated plates to run the EPS Full Size if you wanted to eliminate the need for a plate sandwich.

    Holosun EPS Full Size Warranty

    Holosun has a limited lifetime warranty. Basically everything is covered for the lifetime of the optic except for the electronics, that is covered for 10 years.

    We’ve dealt with Holosun’s warranty department and they are easy to deal with.

    Also when you purchase from Freedom Gorilla, if you have an issue within 30 days we will replace the optic for you free of charge.

    Conclusion

    Overall the EPS Full Size is a great enclosed emitter pistol optic. If you have a full size or compact pistol and are looking for and enclosed emitter that is tough, reliable, and at an affordable price point, this is the optic for you.
