HikMicro Alpex 4K Lite Digital Day/Night Riflescope Review

The HikMicro Alpex 4K Lite Digital Day/Night Riflescope is a compact, lightweight digital optic developed specifically for airgun shooters who want advanced imaging without unnecessary bulk. Featuring a 4K UHD CMOS detector, versatile day and night viewing modes, and a magnesium alloy 30mm tube, it delivers high-end digital performance in a more manageable format. With fast start-up, close-focus capability down to 2 metres, and recoil-activated recording, it is clearly optimised for shorter-range shooting on lighter rifles. The result is a purpose-built scope that balances image quality, usability, and handling for modern airgun setups.

Alpex 4K Lite Performance & Key Features

The Alpex 4K Lite combines high-resolution digital imaging with a wide magnification range, making it suitable for precision shooting at typical airgun distances and beyond. Its 4K sensor and OLED display work together to produce sharp detail in both daylight and low-light conditions, while fast frame rates support smooth tracking.

• 4K UHD 3840×2160 CMOS detector with up to 800 m daytime identification range
• 3.5–20.5× magnification with continuous digital zoom and Picture-in-Picture support
• Multiple image modes including Day, Night, Auto, Green, and Yellow
• Recoil-activated video recording with 50 Hz and 100 Hz frame rate options

Alpex 4K Lite Build Quality & Handling

The scope is built around a durable 30 mm magnesium alloy tube that keeps weight down without compromising strength. At just 450 g without the external battery and only 280.7 mm long, it is well suited to compact air rifles where balance is critical. An IP67 protection rating and wide operating temperature range indicate strong resistance to dust, water, and challenging weather conditions.

Is the Alpex 4K Lite Easy to Use?

User-friendly features are central to the Alpex 4K Lite’s design, helping shooters spend more time shooting and less time adjusting settings. The 1-second quick start ensures minimal delay when powering on, while freeze zeroing and multiple profiles simplify setup across different rifles or ranges.
