The MROC came to me in the review package along with the XP8. I have really enjoyed the products I have evaluated from Atibal thus far. I feel Atibal, along with a few others, serve a middle ground of value to performance that the working man can afford. Not every Rifleman can afford a $900+ optic, hence why I like to T&E some of the more affordable things in life as well as the high-end cool stuff.
The MROC hits that middle ground price point, coming in at $326 at a popular optics retail site. It is a compact prismatic optic which attempts to compete with similar products from Burris, Vortex, Primary Arms, and other brands. In my opinion, it is quite unique. The astute will notice that several of the 4x prismatics on the market look very similar. Could it be that they are made in the same factory? (note the sarcasm!) Well, the MROC doesn’t have to work too hard to grab your attention. It looks different. It is different. It is not like the others.
Let’s have a closer look:
Fit and Finish:
The MROC is a 3×32 optic which weighs in at 14.4 oz. The optic is a prismatic optic housed in what I would call an aluminum chassis. The main components of the MROC are the rear objective, the main body which integrates with the picatinny mount, and the front objective tube which houses the 32mm lens.
It appears that the body is cast aluminum, with the assembly chopped into a 1/3 at the rear and reamed out to the correct dimensions to accept the optical assemblies and electronics package. It is robust, and the walls of the optic seem to be quite thick. On top of the optic is a small rail to accept a mini RDS.
The dials and battery housing are tethered together. Curiously, the choice of battery power for the illumination is a CR2 which I am not as familiar with compared to the CR123. I did manage to find a CR2 at the grocery store, so I guess they are out in the wild of your local supermarket battery section.
The fit and finish are good, with what appears to be a hard coat anodizing on all exposed surfaces.
I noted the optics are bright and clear. There are no dust particles or specs in the glass, and overall glass quality is good and it would be well suited to comparison with its peer products. Part of the optical brightness is related to the huge 32mm objective. That objective gathers plenty of light and funnels it into a 10mm exit pupil. Finger click turrets are 1/2 windage and elevation. They are protected by a o-ring sealed caps and the caps are tethered together to prevent loss on the range. Parallax is set to 100 yards.
The FOV is massive, and is best in class among its peers. Thirty seven feet at 100 yards. This is greater than the 36.8 feet of the 4×32 ACOG, the 28.9 ft of the 3.5×35 ACOG, and 31.5 feet of the Primary Arms 3x prismatic.
The stated eye relief hovers around 2.8 inches. In practice, I found the eye relief is more forgiving than the stated range. I can place my head point-blank or several inches back and still see a useful reticle and image. This is a larger eye-box than the 4×32 ACOG by far. A 10mm exit pupil and 2.8 inches of eye relief combine for a very large eyebox.
The reticle is a chevron with BDC similar to the Trijicon ACOG series. The chevron is small. It is my understanding that Atibal’s community helped choose the reticle, and I cannot place blame as a company wants to sell what the customer wants, but I found the chevron to be small and hard to quickly pick up in a busy environment. Luckily the optic includes illumination. The switch on the side of the optic allows you to pick from 6 illumination settings with a dead space between settings for powering down. My review sample is a early demo model, and the chevron was not cleanly lit so I did not photograph it for fear of giving the wrong impression. Atibal noted that all MROCs shipped out will have a clean, well illuminated Chevron.
I would prefer a crosshair reticle in the future with a 5.56 BDC integrated, and will suggest that to the company. Whether or not it becomes of interest to the customer base remains to be seen. Crosshairs with thick side bars are easy to use in darker environments should the battery die.
The Atibal MROC clamps on to the rifle securely through two bolts. They are not large enough to tighten securely by hand. I felt that more leverage was needed, so I utilized a wrench to tighten the assembly to the carbine. There are two holes to tighten the optic mount with a bullet tip, but the threaded bolt got in the way of the bullet tip making this feature difficult to use. Models imported later this year will be compatible with ACOG mounts and will be offered with a quick detach system. This will be a good change.
The windage and elevation are finger adjustable 1/2 minute clicks. I did not perform a box test as this optic style is set and forget similar to a Trijicon ACOG. Instead I concentrated on ensuring that light to moderate abuse did not displace the optical components and shift zero.
At the range I started by obtaining a 25 yard zero with the 400 meter mark. I moved to the 100 yard line to confirm zero. The optic was on paper at 100 so I started to fine tune the optic. I encountered curious behavior where my windage adjustments R moved the impact up and right. If you are unfamiliar with ACOG or prismatic style optics, the floating roof prism design must be allowed to settle into position after adjustment. Failure to do so will result in chasing a zero that is difficult to evaluate. I banged on the optic several times to settle the prism and continued to fine tune the zero at 100 yards. After the banging the optic, it tracked correctly to my adjustments. Once satisfied with my 100 yard zero, I proceeded to walk the gun back down range shooting and dropping and shooting and dropping. I dropped and tossed the optic from shoulder height and waist height on to hard soil, wood, and grass. I then returned to the 100 yard line to ensure the optic kept zero.
I shot the below five round group which happens to be sub-moa with the Atibal MROC post abuse. Chevrons have a fine tip for a surprising degree of precision. This group was shot with the Ballistic Advantage Hanson profile barrel and 69 grain Sierra Match Kings over 24 grains of Accurate 2230.
The clear glass, forgiving eye-box, and huge field of view made using this optic a good experience. These characteristics blend some of the best stats of both the 4×32 and 3.5×35 ACOG and improves on prismatic performance. It blends a forgiving eye-box, a large field of view, and generous eye relief together far better than other compact optics I have used in the past to include ACOGs and Primary Arms 4x prismatic (now discontinued).
The small reticle should be changed in my opinion. Again, I recognize it is what customers want (they voted in favor of it on Atibal’s Facebook IIRC), but if the batteries are dead the reticle is small and easily lost in the noise during rapid transitions, and especially so in dark forested areas. I would strongly suggest future designs utilize a bold reticle design to catch the eye easier. I had the same complaints of the 4×32 Ta31F so consider it a general complaint of the this style of reticle.
Atibal should keep up this design, and continue to refine the optic with each successive generation. My first changes would be a bolder reticle to go along with the on board illumination and perhaps a switch to a CR123 battery for convenience. Second change would be to integrate the top rail into the optic body for a more robust RDS platform. If something did break, Atibal offers a lifetime warranty.
Overall the optic is robust. Save for the bent RDS mount bending, nothing broke and Atibal noted that this issue is being corrected in future models. The glass and eyebox were excellent and forgiving. The optic survived numerous drops and falls without otherwise cracking, breaking, or losing zero. This optic, should it continue to be refined by Atibal, will evolve into a better and better product with each generation. My sample was tough and capable.
If anyone can discuss the reticle brightness, please comment below. I won’t comment how daylight bright it is as of yet without having a final version. If you have daylight pics, send em my way at [email protected] and I will post them ^ up here ^

Disclaimer: I received this optic as a review package from Atibal. The MROC model I received is an early production prototype. I do not have a financial relationship with Atibal. I have consulted with Atibal for product thoughts and shared my ideas and preferences about various products over the years with the owner. The optic performed as stated above.
