At a quick glance we see that the Comp M4 & M4s are considerably more expensive, a fair bit weightier but performs a leap above the PRO when it comes to brightness and night vision settings as well as battery life and durability, but all this comes with a hefty price tag and you will see that the PRO has a decent range of features regardless, even matching the Comp M4 and M4s on many features.

So is the jump in price worth it for what the M4 series provide, or does the PRO perform well enough to consider saving money and using it as a serious optic? Read on to find out…

What Specs & Features Do the Aimpoint PRO and Comp M4(s) Have in Common?

  1. The Aimpoint PRO and the Comp M4 both feature MOA dots which work best within a 200 yard range.
  2. They are both waterproof to 150 feet.

Since they both use the same reflector red dot system you will find unlimited eye relief using either sight, so the user will have the same view regardless of eye distance from front lens. Both the Aimpoint PRO and Comp M4/M4s are compatible with anti-reflection devices due to the thread at the front lens.

Both optics also feature Aimpoint’s parallax-free optical correction system, which means minimal error of red dot accuracy when the user changes their view through the sight.

Both optics are also compatible with a range of other accessories, including the Aimpoint 3x magnifier and an Aimpoint Concealed Engagement Unit (which allows you to safely view up to 260° around bends), along with usual accessories such as preferred lens caps.

What Are the Key Differences Between the Aimpoint PRO and Comp M4(s)?

Beyond the similarities there are a lot of differences which separate these Aimpoint red dot sights. The differences don’t necessarily make one range ‘better’ than the other, but they will dictate which sight is the right choice for your needs.

Brightness

When it comes to brightness settings, the Comp M4 series wins by a mile with 9 daylight settings and 7 night vision settings where the PRO only has 6 daylight settings and 4 for night vision. These extra settings gives the Comp M4 series more versatility in a range of environmental settings, which increases overall accuracy regardless of surroundings. This is the kind of edge that earns them service in wars over patrolling city streets.

Battery Life

Another key difference is the battery life. If the 3 year constant use battery life of the Aimpoint PRO sounds impressive, then what of the insane 8 year battery life of the Comp M4? To top it off the Comp M4 takes a far more common battery (a single AA) which is cheaper and easier to find than the PRO’s Lithium 2L76 and has almost three times the stamina, pretty impressive.

Weight

While we can find very few difference between these two optics, weight is another factor that you may not think is so important, but you will certainly notice it if you have to run around with your gun all day. The PRO is significantly lighter and also slightly smaller in size. That said, the Comp M4 is known for providing a cleaner, unobstructed view, despite its greater size. Some claim that the larger 30mm optic tube equates to faster target acquisition, adding to the M4 series’ wins.

Field of View

Speaking of field of view, lets take a look at the difference between the Aimpoint Comp M4 and Comp M4s. At first glance they are identical, the only difference being the placement of the battery tube, which begs the question, why two identical products, bar one feature? And the answer is simply preference.

Shape and Usability

On the Aimpoint Comp M4 the battery compartment is higher up where as on the Comp M4s it is lower down, offering a better field of view. Some also prefer the set up of the Comp M4s as it offers greater protection from potential knocks and drops, and it helps to keep a lower profile.

The benefit of having the battery compartment up high, however, is that it causes less problems when it comes to compatibility with accessories. For example, using a 3x magnifier with the M4s can get in the way if you wish to alter your brightness settings. You may find similar problems with other accessories such as handles and mounts that just don’t occur with the M4. But if you know you won’t need to change your settings in action, or you wont be using such accessories, we can’t see why you wouldn’t choose the M4s aside from personal preference overruling all.

Summary and Recommendations

In review, we’re dealing with three great optics here. In no category does the Aimpoint PRO fail, it is simply equal to, or out-done by the Comp M4 series. That is to say that the Comp M4 series are more elite optics for professional and military standard gunners, which is reflected in the price, usually sitting at around double that of the PRO.

The Aimpoint PRO is still a high performing optic whose purpose is to serve low budget police departments. For an optic serving in the city street or on your sporting or hunting rifle, it is a top performer, and exactly the tool you need. It is lighter and more compact and if you have a budget to stick to but care about quality and performance, this is the optic for you. If you’re not taking your gun to a war zone, there’s really no need to splash out all that extra cash for a few more settings and increased battery power of an already impressive battery life.

The Aimpoint Comp M4 series are the superior optic, and lay the claim to Aimpoint’s most robust optic available. You can count on this optic’s durability and you can go the extra mile using this sight. Proven through use by the army and in wars, this is the optic you need if you know you will be in open fire.

Between the Comp M4 and M4s, we see more benefit in choosing the Comp M4s which provide a better field of view with a lower profile, and greater protection should your mounted weapon be dropped. However overall, if your needs aren’t so extreme as to require the Comp M4’s expertises, the Aimpoint PRO will serve you well, and for half the price.
