HikMicro Alpex 4K Lite LRF Digital Day/Night Riflescope Review

The HikMicro Alpex 4K Lite LRF Digital Day/Night Riflescope is a compact, lightweight digital optic developed specifically for airgun use, offering high-resolution imaging in a streamlined 30mm tube format. Built around a 4K UHD CMOS sensor and paired with a fast 40mm F2.0 lens, it delivers detailed observation across short to mid-range distances. Its reduced size and weight make it particularly well suited to lighter, shorter rifles where balance and handling are critical. With advanced digital features and integrated ranging capability on select models, it is designed for shooters who demand precision without unnecessary bulk.

Alpex 4K Lite Performance & Key Features

The Alpex 4K Lite combines a high-resolution sensor with flexible magnification and multiple colour modes to maintain clarity in varying light conditions. Fast start-up times and smooth digital zoom ensure minimal delay when acquiring targets, while integrated recording features capture shots automatically.

• 4K UHD 3840×2160 CMOS sensor delivering fine detail and up to 800m daytime identification range
• 3.5–20.5x continuous digital magnification with selectable step values for precise control
• Integrated Laser Range Finder and ballistic calculation on A40EL models
• Optimised for airgun shooting and shorter-range rifle setups

Alpex 4K Lite Build Quality & Handling

Constructed around a 30mm magnesium alloy tube, the scope balances durability with reduced overall mass. At just 450g–474g depending on model and only 280.7mm in length, it maintains excellent rifle balance, particularly on compact platforms. An IP67 rating confirms full protection against dust and water ingress for confident use in demanding outdoor conditions.

Is the Alpex 4K Lite Easy to Use?

User-focused controls and a clear OLED display make the Alpex 4K Lite intuitive to operate, even for shooters new to digital optics. The fast one-second start-up ensures readiness when opportunities arise, while zeroing and profile management are handled efficiently.

• Freeze zeroing and five zeroing profiles for straightforward setup
• 45mm eye relief and adjustable diopter for comfortable viewing
• Picture-in-picture mode for more precise shot placement

Key Takeaways of the Alpex 4K Lite

The Alpex 4K Lite stands out for its combination of 4K imaging performance, compact dimensions, and airgun-specific design. While its detection ranges and magnification are optimised for shorter distances rather than extreme long-range use, this focus enhances handling and practicality. Shooters using lightweight rifles will particularly benefit from its reduced size and balanced feel. Overall, it is a strong choice for precision-focused airgun and small-calibre rifle applications where clarity, speed, and ergonomics matter most.

HikMicro Alpex 4K Lite LRF Digital Day/Night Riflescope FAQs

What magnification range does the Alpex 4K Lite offer?

The scope provides a digital magnification range from 3.5x to 20.5x, based on a 5.8x base magnification. Continuous zoom is supported with selectable step values, allowing shooters to adjust magnification precisely for different distances. This range is well suited to short and mid-range shooting scenarios.

How does the 4K sensor benefit daytime shooting?

The 3840×2160 CMOS sensor delivers significantly higher detail compared to standard HD sensors. This improves target identification and image clarity, particularly in good lighting conditions. Fine features and outlines are more easily distinguished at distance.

Is this riflescope suitable for night use?

Yes, it supports dedicated Night, Auto, Green, and Yellow image modes in addition to standard Day mode. These modes help optimise contrast and visibility in low-light conditions. The system automatically adapts to changing light when Auto mode is selected.

What display does the Alpex 4K Lite use?

The scope features a 0.49-inch OLED display with a 1920×1080 resolution. OLED technology provides strong contrast and sharp image presentation. Users can select square or sub-round display styles to suit personal preference.

How effective is the integrated Laser Range Finder?

On A40EL models, the integrated LRF measures distances from 3 to 1000 metres. When combined with ballistic calculation, it supports more accurate shot placement. This feature is particularly useful for consistent airgun and small-calibre shooting.

What battery system powers the Alpex 4K Lite?

The scope uses a dual power system with an internal rechargeable lithium battery and an external replaceable 18650 battery. This setup provides up to 7.5 hours of continuous operation under standard conditions. Charging is handled via USB-C, with direct charging supported for the internal battery.

Does the scope record video and audio?

Yes, it supports on-board video recording at 1920×1080 resolution, along with photo capture and audio recording. Recoil-activated recording ensures key moments are captured automatically. All media is stored on the built-in 32GB EMMC memory.

How durable is the Alpex 4K Lite under recoil?

The scope is rated for recoil resistance up to 1000g / 0.4ms. This makes it suitable for airguns and compatible rifles within this recoil threshold. Its magnesium alloy housing further enhances structural durability.

What mounting system does it use?

The Alpex 4K Lite uses a standard 30mm mounting format. This allows compatibility with a wide range of mounts and rifle setups. The familiar tube size also simplifies installation for users upgrading from traditional optics.

Can it be used in extreme weather conditions?

The scope is IP67 rated and operates in temperatures from -30°C to 55°C. This ensures reliable performance in wet, dusty, or cold environments. It is designed for year-round outdoor use without additional protective measures.
