Comp M4: This sight model comes with a AA battery that will last for over 8 years for continuous use. The runtime of this sight is 80,000 hours at medium brightness setting.

Mounting Style

Although both the models support standard Picatinny mounting rails to adjust with a wide range of firearms, their mounting styles are slightly different from each other.

Comp M4: The Comp M4 features a QRP2 mount which has twice the clamping force of the original QRP. The mounting knob is also wider and shorter to improve any aiming action. This mounting style works really well with the Aimpoint 3x Magnifiers.

Comp M5: The Comp M5 model also has similar mounting style but is more flexible to attach and features a military standard mounting system for better adjustment with all Aimpoint’s Micro series sights. As a result, this sight is compatible with both 3x Mag-1 and 6x Mag-1 magnifiers.

On the basis of the mounting system, the flexibility and adaptability of Comp M5 beats the M4 red dot sight.

Durability & Weight

Durability and weight difference can determine a lot of things regarding your shooting experience. That’s why it is important that you take these things into account as well.

Comp M4: When it comes to the housing materials of M4 sights, they are made with aircraft grade aluminum which keeps the sight lightweight and strong at the same time. This red dot sight is also submersible into water up to 150 feet and weighs 9.4 ounces.

Comp M5: The Comp M5 sight has similar housing materials as the M4 model. However, in order to maintain the military standard this sight is more rugged than the M4 sight and more sustainable to recoiling. Also, because it weighs less than the M4 model being only 5.2 ounces, it is easier to carry and works great with handguns.

Looking at the durability and weight of these models, it is clear that the M5 model is much stronger and portable than the M4 series.
