Features
- Open reflex sight for rapid target acquisition of close range targets out to 100+ yards. Open reflex sights offer better peripheral vision and greater situational awareness than enclosed tube red dots.
- Comes with a parallax free circle cross reticle with a 2 MOA center dot. Electronically controlled illumination with multiple levels of intensity up to daylight bright.
- The Ares Red Dot comes with a custom optical system with minimal power draw and Shake Awake motion sensing technology. The dot will automatically shut off after one hour and re-activate instantly upon movement, providing tens of thousands of hours of battery life on a single battery, up to 10 times longer than LED powered red dots.
- Integrated picatinny recoil lugs compatible with picatinny mounting platforms. For rifles and long guns. Not for use with pistols or handguns.
- All Monstrum products are backed by a lifetime guarantee.

I plan to keep this review updated. Current Summary (updated 12/15/24): 5 Stars - Once you put the battery in (+ up) securely, *then* begin to adjust brightness using the Increase button. It takes several iterations to get the brightness to be visible indoors! - Mounts solidly. Contains all the subcomponents and items it should. Controls work, primary functions appear to work (hold of zero undetermined). - Auto Off Works. Shake Awake works. The sensors are very sensitive, and don't *appear* to work. - Works well in "cold" weather. - (Range Test and Initial Zero Hold): Still pending. - (Zero after 500 rounds): Still pending. LOG: 12/15/24 I was hoping for subzero temps. The best I was able to find outdoors was 12-16 degrees F. At T minus 72h I placed the device in my home freezer (19 F). At T minus 8h I placed the device and a digital thermometer outside. I turned the device ON. At the time I placed the device it was 14 F. At Validation time, the temp was 15 F, and the Ares switched on as I picked up the thermometer to read it (Shake Awake is sensitive). "Cold" weather test OK (which is a credit to the battery and the device), but I'm hoping someone will test the Ares in subzero F! 12/2/24 After a failure with initial testing of AO/SA, I grabbed a second unit and put on a shelf in a corner. The Shake Awake is even more sensitive than the Sig Romeo 5 - the slightest vibration resets the Auto Off/Wakes the sight. After this revelation, I discovered the first sight *also* had functional, though sensitive AO/SA. 12/1/24: Auto Off does not seem to work, so it is difficult to make a precise statement on Shake Awake, unless the threshold for Shake Awake (vibration/motion) is absurdly low OR the timeframe for Auto Off is absurdly long. Monstrum reports Auto Off at 1h. I placed the optic, mounted, standing in a vice, on a table and turned the optic to ON with the keypad. I could see the reticle from over 6 feet away - the idea was to isolate the optic from vibration after failed attempts to observe Auto Off. I then checked the reticle every 30 minutes for 2.5h. It remained On. I then extended the pause for 8.5 h. Still On after 11h total. As a result of these experiments, and that Monstrum advertises Shake Awake when there is no Shake Awake, I still give 5 stars, because I can only give 5 stars. It is a $29.99 Optic that is otherwise solid, or potentially so! Initial Review: 5 Stars *** I thought it was a DUD: It turned out that the initial brightness is VERY LOW. Keep elevating brightness after the battery is installed (+ side UP)! *** This Open Reflex Red Dot with Shake Awake is priced competitively with the BB gun/Airsoft items. My purchase was $29.99. Mine came with [2] cleaning cloths, [1] battery (CR 2032?) and all the wrenches/gizmos necessary to attach to a firearm. The rest of this review is *relative* to the very capable and much more expensive Sig Romeo MSR. TLDR: The Sig MSR and Monstrum ARES are both very capable not-warfighter red dot sights. There are very real differences between these two products (TX CAPITALISM!) and many more distinctions-without-a-difference. I can, and did, purchase [3] ARES sights for the same price I (happily) purchased a discounted MSR. I do not YET know if the ARES will hold zero - the MSR absolutely does. - Both sights have good warranties, and I've used both a SIG and Monstrum warranties. - Both sights use Torx wrenches for fitment. The MSR Torx is way cooler as it also has the flat driver needed for elevation and windage adjustment. The Ares uses the same Torx for W/E adj. The Ares attaches to the pic rail with two bolts, and two indexing surfaces for the pic rail 'valleys'. The MSR has one bolt and a spring loaded clamp. Both mount solidly. - Both are quite aesthetically pleasing, and solidly overbuilt, although in very different ways. The MSR looks like a deadly dieselpunk artifact, with turrets and a skeletonized riser. The Ares looks like it is Starfleet Marines kit. - Both have absolute co-witness on Milspec ARs, both work exceptionally well in bright light (MSR is tube-style), Ares has a *laser* diode (vs LED). What I don't know is if one is brighter than the other in an extreme situation I am unlikely to face at the local marksmanship range. - Both are IPX-7 for fog/water resistance. - Both have 2 MOA dots; the Ares complements the 2 MOA dot with a bull ring and crosshairs. - Both are a bit fidgety to dial in brightness - the Ares seems like it is OFF at lower illumination. The MSR, with an analog dial lets you know otherwise, but the dial is very firm. - Both are intended for 100-ish m. The Ares, with the ring and crosshair provides an index for Kentucky elevation at greater ranges, lacking on the MSR. Below 100m it is preference (some might find the Ares reticle distracting, some might have difficulty using the MSR dot under stress). - Ares has 'shake awake' illumination, MSR does not (the Sig Romeo 5, at 20% more than the MSR and 400% more than the Ares, does). The Ares uses a much more common battery (CR 2032) than the MSR's (CR1632). I do not know which battery will last longer in practical usage. - The MSR does come with see through lens caps, which are also semi-integral, quick to deploy (and fidgety to close). The Ares does not. A rubber band and a plastic bag on the Ares serves as a field expedient solution for those who need to protect their IPX7-rated sights. - The MSR holds zero, rock solid, over hundreds of rounds (and my ROMEO5, over thousands). I'll report back on the ARES once I have the real-world practical experience.

Larger and heavier than I expected it to be, but it is heavy-duty metal (steel, not pot metal) and strong enough to hammer nails with. It has a large clear viewing lens with a thick metal ring protecting it, a bright target circle with crosshairs that shuts off after 10 minutes, and has a shake-awake feature that works great, eliminating the need to remember to turn it off or trying to turn it on when you need it. The finish is well-done, not fancy, but not cheap-looking. For the price, I bought 2 of them, and the more I play with it, the more I am impressed with its solid functionality. At first, I thought it a bit heavy and large for my 10/22, but it lines up great, easy to acquire sight picture with that huge viewing screen, and after getting used to it, the weight is really not noticeable when installed. Not sure how it will hold zero, as I haven't shot with it, but it is not a delicate piece of plastic or cheap sheet metal like others in this price range, I don't see how that would be a problem. It uses standard 2032 Li-Ion batteries. The elevation and azimuth adjustments are very nice, clickable and precise. I didn't want to like it at first, but it is pretty amazing for the price and have grown to like it. Good: Low price, solid metal, wide clear viewing port, shake-awake feature saves your battery. Not so good: Heavy, maybe a little too large for pistols.

Great build quality on a budget, love the shake awake and the brightness selection, looks great on rifles, the draw distance does well farther out, if you are using a braced pistol, well it isn't so good, the medical is blurry and is too large if it isn't far enough out on the rail, used it for my rifle instead, also the glass, even when the Laser is off is muddy and red-washed, buy for a budget, nor for an everyday use
