Aimpoint Comp M5: a review
Aimpoint describes the Comp M5 as a “…high performance red dot sight developed to withstand extremely tough handling and environmental situations…designed for the “both eyes open” method [Bindon Aiming Concept] which greatly enhances situational awareness and target acquisition.” It’s built by a company with an excellent reputation and has a history of great reviews. I recently picked an Aimpoint Comp M5 from a friend was unabashedly excited by what I was holding. As always (at least in my experience) Aimpoint’s quality is second to none. Read on to see why I think so.
Aimpoint Comp M5 Features
Before I go too far about what I did with the Aimpoint Comp M5, let’s talk about the optics features. The CompM5 is run by a single A.A.A. battery. This is a great feature for those end of the world situations you might find yourself in because even the Walking Dead cast can find the Triple As in those raided stores!
The CompM5 has a battery life of 5 years (50,000 hours) at position 7, and 1 year at position 8. It has 4 NVG settings if you are one that likes to goon out in the dark.
Dot, Mounting Surface, and Lens Covers
It has a crisp easy to use 2 M.O.A. dot, which is daytime bright—as all Aimpoints H1’s and T1’s I have used are. The mounting surface is the same as the Aimpoint H1’s, T1’s and T2’s, so you are sure to have some sort of mount sitting around if you are like me. The optic is shipped with lens covers, which I think is a major improvement over the H1 and T1’s I currently have.
The objective lens is clear, allowing you to use it even in the rain and snow. The front lens cap is solid plastic. It has an operating temperature range of -49 / +160 degrees Fahrenheit, which according to me will work in hell!
So now that we have ended with the long list of features, let’s move on to my experience, mounting, zeroing, and overall assessment of this optic.
Mounting the CompM5
So to start with, I mounted this to an A.D.M. T1 Micro NV Height mount. This mount places the optic dot at 2.33” above the upper receiver rail. At this height the optic mount allows you to get a more upright head position as well as easier workability under helmet-mounted NVG systems. Mounting the CompM5 to the ADM NV mount was simple and took only 10 minutes. For those individuals mounting an optic to its mount, I recommend they use some form of Loctite. I usually use blue for these types of jobs.
When mounting a red dot optic to my ADM Mod 1 UIC rifle, I normally mount it to the forward half of the upper receiver. I do this for several reasons, it seems (at least to me) to center the weight of the rifle, as well as moves it forward enough for me to get my helmet-mounted NVG behind the optic. If you so choose, it also allows you to mount a 3x or 6X flip to side magnifier behind the optic.
The Zeroing Process
Moving to the range, I start the zeroing process at the ten-yard line. A few years back I attended a Frank Proctor carbine class. In the class, Frank taught a method of zeroing at 10 yards using point of impact that is approximately 1.5” lower than the point of aim. I currently use this method every time I zero. It has saved me heartburn and time during the zero process. For my optic height, this isn’t going to be exactly correct. None the less, this will get me on target at 50 yards to establish a zero. You can get a printable 10-yard zero target at Jerking the Trigger if you so desire! When adjusting the windage and elevation at this distance you will need to use about three times the clicks than you do at the 50-yard line.
Starting with 55 grain FMJ
Once at the 50-yard line, I used Aimpoints downloadable Comp M5 zeroing target. These targets give you all the information needed to complete a quick and easy zero. I get into a solid prone position usually, unsupported except the magazine, elbows, and body. I started the zeroing process using 55 grain FMJ, firing about 1 round every 5 to 10 seconds, until I fired 5 rounds.
Using the directions on the Aimpoint target, for my first 5 rounds, I needed to move the group down 23 clicks and 8 clicks to the right. Each click at 50 yards for the Comp M5 is ½”, which is similar to most red dot optics.
I then fired a second group which confirmed the optic adjustments are correct. This second group was inside the yellow circle in the center of the target.
Based on the second group being a little to the left and high, I moved the windage 3 clicks to the right and 2 clicks down on the elevation. On the third group, I had 4 of the 5 rounds in the center of the target directly on the centerline. Being that this is cheap FMJ ammunition I didn’t expect much more than a few inch group.
Next: SPG 55 grain Soft Point
I then moved to zeroing the optic with Speer Gold Dot 55 grain Soft Point. On my first 5 round group, the rounds shot to the right and low of the center line. Before my second Speer Gold Dot zero, I moved the optic elevation up 2 clicks and left 3 clicks. On my second group, I placed all 5 rounds dead center of the target, in a group approximately 1” in size. For me, this rifle and optic were zeroed, so I moved to other types of shooting.
Final Thoughts on the Aimpoint CompM5
Putting the optic through its paces has been a pleasure. The optic is lightweight and rugged like all other Aimpoint products. Working through the optic is easy, and the glass is clear. It seems to me that Aimpoint reduced the amount of tinting on the forward lens, making it easier to see through.
After using the CompM5 through several range sessions and approximately 1000 rounds, I have noticed zero issues with the optic. I have run the rifle hot, used it in the rain and snow, and this thing just doesn’t fail. I really liked the ability to use the lens covers, especially the rear clear lens cover. The 2 MOA dot is perfect for any shooting engagement close or far. I find that it makes distance shooting a breeze since it isn’t covering up the target. If you feel it is too small for close up shooting, crank up the illumination dial and bloom that dot. I have had zero issues with the battery life as of this writing and don’t expect to for some time.
You can’t go wrong!
If you are in the market for a red dot optic that has a battery life measured in years using a AAA battery, is rugged as all hell, comes with great lens covers, and comes from a company known for quality, I highly recommend the Aimpoint CompM5.
The COMP M5 in Aimpoint’s words:
The CompM5 is a high performance red dot sight developed to withstand extremely tough handling and environmental situations without adding much weight to the user’s equipment. Aimpoint red dot sights are designed for the “both eyes open” method which greatly enhances situational awareness and target acquisition. Thanks to the optical design the red dot follows the movement of the user’s eye while remaining fixed on target, eliminating any need for centering.
The CompM5 allows for unlimited eye relief and is compatible with Aimpoint 3XMag-1 and 6XMag-1 magnifiers as well as all generations of Night Vision Devices (NVD).
The battery life for the CompM5 is over 5 years of continuous use while at the pos. 7, more than 1 year of use at pos. 8, and more than 10 years at NVD settings (pos. 1 to 4).
