What is the battery life of the Aimpoint M5 and what kind of battery does it use?
The Aimpoint Comp 5 features a battery life of over 50,000 hours, which is more than 5 years of constant operation. This performance is achieved on brightness setting 7. The sight operates on a single, commonly available AAA battery.
Is the CompM5 compatible with magnifiers and night vision devices?
Yes. The Comp M5 Aimpoint sight pairs perfectly with Aimpoint 3XMag-1™ and 6XMag-1™ magnifiers. It is also fully compatible with all generations of night vision devices and includes 4 dedicated night vision compatible brightness settings.
How durable is the CompM5 optic?
The Comp M5 Mount Aimpoint is designed to be extremely rugged and durable. The sight housing is constructed from hard-anodized aluminum alloy for optimal protection of the internal components. It is submersible to 150 feet (45 meters) and is built to withstand an operational temperature range from -49°F to +160°F.
What does "operationally parallax-free" mean?
"Operationally parallax-free" means the visible red dot remains parallel to the bore of your weapon regardless of the angle your eye is in relation to the sight. This allows the user to focus on the target without worrying about centering the dot inside the sight. If you have a proper zero, where the dot is on the target is where your shot will go.
What is the difference between the Aimpoint - CompM5 Red Dot Reflex Sight?
The primary difference is the location of the battery compartment. The CompM5 sight has a high battery compartment, while the CompM5s™ has a low battery compartment.

Aimpoint Comp M5 vs Pro
The Aimpoint CompM5 and Aimpoint PRO are both rugged, reliable red dot sights, but they are designed to fill different operational needs, primarily distinguished by their size, weight, and power source. The PRO is a full-sized duty optic designed to be an all-in-one, ready-to-go package at a budget-friendly price point. The CompM5, by contrast, is a more modern and compact optic designed to take up minimal space on the weapon platform while offering extreme ruggedness and durability.
The most significant operational difference is the power source and its impact on the optic's footprint. The PRO is a larger, heavier optic weighing 220 g (7.8 oz) for the sight only. It is powered by a single DL1/3N battery, which provides over 3 years of constant-on use. The CompM5 is considerably lighter at 148 g (5.2 oz) and uses a more common AAA battery to provide over 5 years of continuous operation. For an operator focused on minimizing weight and bulk without sacrificing performance, the CompM5 presents a clear advantage.
Key Differentiators:
- Battery Type: The CompM5 uses a single AAA battery , while the PRO uses one DL1/3N battery.
- Battery Life: The CompM5 offers 50,000 hours (over 5 years) of operation , while the PRO provides 30,000 hours (over 3 years).
- Weight (Sight Only): The CompM5 weighs 148 g (5.2 oz). The PRO is heavier, weighing 220 g (7.8 oz).
- Dimensions: The CompM5 is designed to be more compact , whereas the PRO is a full-sized 30mm tube sight.
CompM4 vs CompM5
The choice between a CompM4 and a CompM5 often comes down to a critical logistical and operational preference: battery type versus size and weight. The CompM4 series is the standard infantry sight for many NATO countries, including the U.S. Army's M68CCO, and its defining feature is its use of a single AA battery. This allows for over 80,000 hours (8 years) of constant operation and offers the logistical advantage of using one of the most common batteries in the world.
The CompM5, however, was engineered for operators who prioritize a minimal footprint on the weapon rail. It achieves this by using a smaller AAA battery, which still provides an impressive 50,000 hours (over 5 years) of runtime. This design choice makes the CompM5 significantly lighter and more compact than the CompM4. The CompM5 weighs only 148 g (5.2 oz), while the CompM4 sight is substantially heavier at 268 g (9.5 oz). The CompM4 also features more brightness settings, with 9 daylight and 7 NVD settings, compared to the CompM5's 6 daylight and 4 NVD settings.
Key Differentiators:
- Battery Type: The CompM4 uses a single AA battery. The CompM5 uses a single AAA battery.
- Battery Life: The CompM4 offers 80,000 hours (over 8 years) of operation. The CompM5 offers 50,000 hours (over 5 years).
- Weight (Sight Only): The CompM5 is lighter at 148 g (5.2 oz). The CompM4 weighs 268 g (9.5 oz).
- Brightness Settings: The CompM4 has 16 total settings (9 daylight, 7 NVD). The CompM5 has 10 total settings (6 daylight, 4 NVD).
CompM5 vs T2
This comparison is between two of Aimpoint's most advanced, compact red dot sights. The choice hinges on the operator's priority between absolute minimum size/weight (T-2) and the use of a more common power source (CompM5). The Micro T-2 is the pinnacle of compact, lightweight design, weighing an exceptionally light 84 g (3.0 oz) for the sight only. It achieves this with a CR2032 coin battery, which provides 50,000 hours (over 5 years) of service. Its housing is reinforced for extreme ruggedness, and it includes protective flip-up lens covers.
The CompM5 offers the same 50,000-hour battery life but uses a readily available AAA battery. This results in a slightly larger and heavier optic at 148 g (5.2 oz), but one that is still exceptionally compact and light for a professional-grade sight. Another key difference is durability in wet conditions; the CompM5 is submersible to 150 feet (45 meters), whereas the Micro T-2 is submersible to 80 feet (25 meters). Both optics feature advanced lens coatings for superior dot clarity and are compatible with all Aimpoint magnifiers.
Key Differentiators:
- Weight (Sight Only): The Micro T-2 is lighter, weighing 84 g (3.0 oz). The CompM5 weighs 148 g (5.2 oz).
- Battery Type: The CompM5 uses a single AAA battery. The Micro T-2 uses a single CR2032 battery.
- Submersibility: The CompM5 is submersible to 150 feet (45 meters). The Micro T-2 is submersible to 80 feet (25 meters).
- Dimensions: The Micro T-2 has a smaller overall physical footprint than the CompM5.
