Aimpoint – CompM5s – Red Dot Sight – 2 MOA – CS Firearms

Description

The Aimpoint CompM5s red dot sight is engineered for shooters who demand a rugged, lightweight optic that performs across a range of scenarios commonly encountered in the United States—from three-gun competition stages in the Midwest to patrol carbines carried by law enforcement officers, and from varmint hunting on private land to home defense setups in suburban neighborhoods. This sight brings the proven reliability of Aimpoint’s military-grade electronics into a compact package that weighs just over 3 ounces, making it a practical choice for those who want to reduce weight without sacrificing battery life or optical clarity. Whether you are a competitive shooter tracking steel targets at speed or a hunter needing a fast-acquisition optic for low-light conditions, the CompM5s offers a consistent 2 MOA dot that holds zero under recoil and environmental stress.

What This Product Is and Who It’s For

The Aimpoint CompM5s is a red dot sight designed for use on rifles, carbines, and shotguns, offering a 2 MOA dot that provides a balance of precision and speed. This optic is built for target shooters who want a repeatable aiming point for paper or steel at known distances, home defense users who need instant target acquisition in confined spaces, and hunters who require a lightweight sight that won’t drag down a field rifle. Collectors and firearms enthusiasts will appreciate the CompM5s as a modern upgrade for classic platforms like the AR-15 or a dedicated upper receiver build, while law enforcement and security professionals often choose this model for its durability and long battery life. It is not a magnified optic, so it is best suited for shooters who prefer both-eyes-open aiming at distances typically under 300 yards.

Feature Deep-Dive

The CompM5s uses a single CR2032 battery that provides up to 500,000 hours of continuous operation at a mid-range brightness setting. This translates to over 57 years of use if left on at that setting, which means you can install the battery and forget about it for the practical lifespan of the sight. The battery compartment is tool-less, allowing for quick replacement without removing the optic from the firearm, which is a practical advantage for shooters who keep a spare battery in their range bag or gun safe.

The 2 MOA dot is produced by a high-efficiency LED that maintains a crisp, round aiming point across all 10 daylight brightness settings. The dot does not bloom or distort at higher brightness levels, which is important for shooters who transition between indoor and outdoor lighting conditions. The seven additional night vision compatible settings allow the sight to be used with Generation I through IV night vision devices without washing out the image, making this optic suitable for low-light or no-light applications.

The housing is constructed from a high-strength aluminum alloy with a hard anodized finish that resists corrosion and wear. The sight is nitrogen-purged and sealed to prevent internal fogging, and it is submersible to 35 meters, meaning it can withstand heavy rain, mud, or accidental submersion without failure. The lens coatings reduce glare and reflections, which helps maintain a clear sight picture when the sun is low on the horizon or when shooting from shaded positions.

Windage and elevation adjustments are made via capped turrets that provide tactile clicks, each click moving the point of impact 0.5 MOA at 100 yards. The adjustments are repeatable and hold zero under recoil from calibers up to .308 Winchester and 12-gauge slugs. The turrets are flush with the housing when capped, reducing the risk of snagging on gear or brush during movement.

The CompM5s includes a QRP2 (Quick Release Picatinny) mount that attaches securely to MIL-STD-1913 rails. The mount features a lever-operated clamping mechanism that allows for installation or removal without tools, and it returns to zero within a fraction of an MOA when reinstalled on the same rail. This is useful for shooters who maintain multiple uppers or who need to transfer the sight between firearms.

One design feature that sets the CompM5s apart from earlier Aimpoint models is its compact footprint. At just 2.5 inches in length and 3.1 ounces, it is shorter and lighter than the CompM4 or M5, making it a better fit for handguard-mounted positions on shorter barrels or for shooters who prioritize weight savings on a patrol rifle or competition gun. The sight’s low profile also allows for lower 1/3 co-witness with standard iron sights.

Ideal Use Cases

The Aimpoint CompM5s is well-suited for target shooting and range practice, where its 2 MOA dot provides a precise aiming point for slow fire or rapid strings on paper targets at 25 to 100 yards. Home defense users benefit from the sight’s unlimited eye relief and parallax-free design, which allow for fast target acquisition from awkward positions or when wearing body armor. Hunters who pursue game in open terrain—such as coyotes, hogs, or varmints—can use the CompM5s on a lightweight carbine for quick shots at moving targets. For competition shooters in divisions that allow red dot sights (such as USPSA PCC or 3-Gun), the CompM5s offers the reliability and battery life needed for multi-day matches. It is not designed for concealed carry due to its size and mounting requirements, but it works well on truck guns, bed-side rifles, and patrol carbines.

Compatibility Notes

The CompM5s is compatible with any firearm that has a Picatinny (MIL-STD-1913) rail, including AR-15, AR-10, HK-style rifles, AK pattern rifles with railed dust covers, and shotguns with rail sections. The included QRP2 mount fits standard 30mm rings if you prefer an aftermarket mount. The sight is rated for use on firearms chambered in .223 Remington, 5.56 NATO, .300 Blackout, 7.62x39mm, .308 Winchester, 6.5 Creedmoor, and 12-gauge slugs. It is not intended for use on pistols without an adapter, as the mount is designed for long guns. The CR2032 battery is widely available at hardware stores, drugstores, and online retailers. Aimpoint offers a range of optional accessories, including kill flashes, lens covers, and various mount heights, which are available through CS Firearms.

FAQ

• Can this sight be shipped to my address in the United States? Yes, CS Firearms ships the Aimpoint CompM5s to all 50 states, including Alaska and Hawaii. We ship via UPS or FedEx with adult signature required. No FFL transfer is needed for this optic, as it is not a firearm or receiver.
• Do I need to go through an FFL transfer to purchase this sight? No. The Aimpoint CompM5s is a firearm accessory, not a firearm. It can be shipped directly to your home or business address without an FFL transfer. Standard shipping restrictions apply for ammunition or firearms, but this optic is not regulated under the Gun Control Act.
• Is the CompM5s compatible with all ammunition types? The sight is mechanically compatible with any firearm it can be mounted on, but it is rated for calibers up to .308 Winchester and 12-gauge slugs. Heavier recoil from magnum rifle cartridges (such as .300 Win Mag or .338 Lapua) may exceed the sight’s design limits, though it has been used on such platforms in some cases. Always check with the manufacturer for specific recoil ratings.
• What is the warranty on the Aimpoint CompM5s? Aimpoint provides a 10-year limited warranty against defects in materials and workmanship from the date of purchase. The warranty covers the sight housing, electronics, and lens coatings, but does not cover damage from misuse, unauthorized modifications, or normal wear. CS Firearms honors all manufacturer warranties, and we can assist with warranty claims if needed.
• Can I return the CompM5s if it does not fit my rifle or I change my mind? CS Firearms accepts returns on unused, unopened optics within 30 days of delivery for a refund of the purchase price minus shipping and a restocking fee. If the sight has been mounted or used, we cannot accept it for return due to hygiene and inspection standards. Please inspect the sight upon receipt and test fit it on your rail before final installation.
