DESCRIPTION

Redefining compact precision, the ALPEX 4K Lite A40E is a cutting-edge digital day and night vision scope purpose-built for airgun hunters and pest control professionals. Powered by an ultra-high-definition 3840×2160 CMOS sensor and a 40mm F2.0 lens, it delivers unmatched clarity with an 18.7m field of view at 100m—day or night. Compact yet powerful, this scope sets a new benchmark in lightweight field optics

Engineered for low-light dominance, the A40E features adaptive 4K imaging and advanced rendering at 50hz for static surveillance and up to 100hz at 1080P for high-speed target tracking. Whether you're scanning a distant nest or pursuing a fast-moving quarry, the result is zero blur, maximum clarity, and unwavering precision. An external IR torch can be added for enhanced nocturnal range.

Weighing just 450g and 25% slimmer than conventional optics, the A40E’s 30mm magnesium alloy Tube integrates seamlessly with any air rifle system. This rugged yet lightweight design supports long treks across farmland and tight maneuvering in dense cover. The compact form factor is balanced for agility without sacrificing durability or optical performance.

Equipped with a 0.49-inch OLED display (1920×1080), continuous zoom up to 20.5x, and smart day/night/auto modes, the A40E brings tactical flexibility to any engagement. Record every shot with built-in audio and 32GB EMMC storage. Its dual-power system—internal lithium and external 18650 batteries—delivers up to 7.5 hours of uninterrupted operation in field conditions.

Please note: Due to distribution rights and agreements we can only sell HIK-MICRO products to residents of the UK.
