HIKMICRO Alpex 4K Lite A40EL LRF Night Vision Scope *Open Box*

Open Box Return – Previously scope-mounted, then returned due to a change of mind. Excellent condition, complete with all original accessories and packaging, covered by a 3-year warranty, and updated to the latest firmware (July 2026).

The HIKMICRO ALPEX 4K A40EL is engineered for shooters who demand precision without compromise. Combining a 3840×2160 4K CMOS sensor with a 40mm F2.0 lens, this digital day and night vision scope delivers exceptional image clarity and target recognition in virtually any lighting condition. What sets the A40EL apart is its integrated 1000-meter laser rangefinder with real-time ballistic calculation. This system automatically adjusts reticle holdover based on distance and pellet type—ensuring deadly accuracy whether you're zeroing in on rats at 30 meters or challenging a 90-meter shot with a .25 caliber.

Designed for true around-the-clock use, the A40EL leverages adaptive low-light technology to deliver uncompromised detail at dawn, dusk, and in total darkness. Operate in five vision modes—Day, Night, Auto, Green, and Yellow—tailored for varied terrain and ambient light. With dual imaging frequencies (50Hz in 4K, 100Hz in 1080P), the scope ensures crystal-clear static observation and seamless motion tracking with zero blur. A rapid one-second startup puts the A40EL into action instantly, critical for reactive scenarios in the field.

At just 474g and 25% slimmer than conventional optics, the ALPEX 4K A40EL is purpose-built for airguns and tactical manoeuvrability. The 30mm magnesium-alloy tube form factor ensures universal compatibility and lightweight handling—perfect for stalking pests in tight quarters or carrying across open farmland. Intuitive controls are designed for gloved or wet-hand operation, making it field-ready in every sense.

The A40EL is powered by an internal lithium battery with support for an external rechargeable 18650 cell, providing up to 7 hours of continuous operation. Recoil-activated recording with built-in audio and 32GB of internal EMMC storage allows you to capture every shot with forensic clarity. Whether you're targeting, ranging, recording, or navigating at night, the A40EL is the total field solution for modern airgun hunters.
