Aimpoint Battery Cap

• Sealed battery replacement: This Aimpoint battery cap restores the battery compartment seal, helping maintain reliable power delivery and environmental protection in the field.
• Correct fit for legacy sights: It is made for compatible Aimpoint red dot sights produced before 2015, so older optics can stay in service with the proper replacement part.
• Includes O-ring and sealing: The replacement kit includes the sealing components needed for a proper install, reducing the risk of moisture or dirt reaching the battery compartment.
• Simple maintenance item: A fresh battery cap is an easy way to address wear or damage at a common service point without replacing the sight itself.

About the Aimpoint Spare Parts Series

Aimpoint spare parts are intended to keep established red dot sights in service with the correct factory-fit replacement components. Within the company’s lineup, these parts support both current and earlier sight families, making them especially relevant for shooters, hunters, and professional users who rely on proven optics over many years of use. Rather than treating a worn cap, screw, or sealing component as a reason to retire an otherwise sound sight, the spare-parts range allows practical maintenance with parts designed around the original product geometry.

For Aimpoint users, that matters because the company’s sights are often chosen for long-term durability, constant readiness, and dependable field use. Small components such as battery caps and seals play an important role in preserving that reliability. In this product family, the emphasis is not on adding new features, but on maintaining the sight’s weather resistance, battery retention, and day-to-day usability. For owners of older hunting optics or tactical optics, genuine replacement parts are a straightforward way to preserve the original handling and function of the sight.

About the Aimpoint Battery Cap

The Aimpoint Battery Cap is a dedicated replacement part for compatible Aimpoint PRO, Comp M3, Comp ML3, Comp M2, and Comp ML2 sight models produced before 2015. Its job is simple but important: it closes and secures the battery compartment while helping preserve the seal that protects the power source from moisture, dust, and general field exposure. On a working red dot sight, that small interface has a direct effect on reliability, because stable battery contact and proper sealing are essential to consistent operation.

This replacement kit includes an O-ring and sealing components, which makes it more than just a threaded cap. In practical use, that helps restore the original protective function of the battery compartment after the old cap has been lost, damaged, or worn through repeated battery changes. For users keeping an older sight in service on a hunting rifle, training carbine, or general-purpose firearm, replacing the cap with the correct factory part is a sensible maintenance step that supports dependable operation without altering the optic’s original handling.

Because it is a genuine Aimpoint spare part, the cap is intended to match the fit and function of the compatible sight bodies. That matters most on established optics that are still mechanically sound and optically useful, where a correct replacement part helps maintain the sight rather than improvise a repair.

About Aimpoint

Aimpoint AB was founded in February 1975 in Malmö, Sweden. The company introduced Aimpoint Electronic in 1975, recognized as the world’s first commercial red dot sight, and that early start established Aimpoint as a specialist in this category. Aimpoint is a Swedish manufacturer specializing in red dot sights, with products developed for hunting, sport shooting, and professional users.

Over time, the company expanded its range with product families aimed at different applications, including the smaller Micro series for hunters and the Acro series, introduced in 2018, for enclosed-emitter pistol sight use. Across these lines, Aimpoint’s reputation rests on focused expertise in non-magnified aiming optics and on maintaining product support for both current and earlier sight models.
