Some optics tweak what already exists. Others redefine what’s possible for budget night vision.
The HIKMICRO Alpex 4K Lite (A40E) sits firmly in the second category.
This isn’t just a cheap digital scope. It isn’t a toned-down version of the original Alpex. It’s a purpose-built, ultra-light, close-range night vision system designed specifically for air rifle pest control — and it delivers performance that simply shouldn’t be achievable under £500.
A New Standard for Sub-£500 Digital Night Vision
The first thing that separates the Alpex 4K Lite from the competition is the sheer image quality. Its UHD 4K CMOS sensor (3840×2160) and fixed F2.0 lens deliver exceptional clarity, contrast and light-gathering efficiency. The result is a picture that stays sharp edge-to-edge, even at the limits of your IR beam — something most digital scopes at this price simply cannot match. That means more detail, more confidence and far better shot placement in dark, cluttered environments.

4K Sensor & Optimised F2.0 Lens
This combination is responsible for the Lite’s biggest real-world advantage: unbelievably clear low-light visibility without excessive reliance on IR.
The F2.0 lens captures more ambient light, allowing you to spot movement — like a rat’s tail flick or whiskers brushing against a feed sack — even before switching on illumination. This natural low-light performance is a major benefit in barns, sheds and farm buildings where IR can reflect harshly off metal, water troughs or tin walls.
Designed for Close-Range Precision
Most digital scopes are built for foxing ranges — 80 to 150 yards — leaving air rifle shooters struggling with soft focus at close quarters.
The Alpex 4K Lite solves this with a minimum focus distance of just 2 metres. Whether a rat appears across a barn or beneath your feet at a grain bin, you can dial in a razor-sharp image instantly.
At 10 yards — the bread-and-butter distance for ratting — the Lite consistently outperforms scopes costing twice the price.
True Day & Night Performance
One of the biggest value points is that the Alpex Lite genuinely works as a full-time day AND night scope.
By day, it behaves like a high-quality digital optic with bright, vivid colour reproduction and excellent handling of harsh light or reflective surfaces.
By night, it switches into a highly capable NV system with zero blooming or “white-out” issues — a common problem in metal sheds or feed stores.
Perfectly Tuned for Air Rifle Distances
With a base magnification of 3.5x, the Lite strikes the perfect balance between field of view and target detail. At typical pest-control ranges — 10 to 30 yards — this gives you the ability to scan quickly while still retaining excellent precision.
The 4K sensor ensures the digital zoom stays usable, avoiding the heavy pixelation seen in older NV units.
The 40mm lens also provides a wider viewing angle than the 50mm full-size Alpex, making it much easier to track fast-moving rats darting across a barn floor.
Ultra-Lightweight & Exceptionally Balanced
Weighing roughly 450g, the Lite is less than half the weight of the full-size Alpex 4K. This dramatically improves the feel of your rifle, preventing the top-heavy, unbalanced sensation common with digital optics.
It mounts using standard 30mm rings, meaning no proprietary mounts, adapters or extra costs — just fit it straight on and go.
Smart Recording Features
The Recoil Activated Video (RAV) system works flawlessly, automatically saving footage before and after each shot — with zero button-pressing required.
Whether you’re submitting evidence for pest-control work or posting clips via the HIKMICRO Sight app, RAV ensures every moment is captured reliably.
A Battery System Built for Long Nights
A dual-battery system — consisting of a built-in rechargeable cell plus a replaceable 18650 — gives the Lite over 7 hours of runtime.
You can hot-swap the external battery in complete darkness without rebooting the scope, ensuring you never lose visual contact during a busy session.
Final Verdict: The Sub-£500 King of Ratting Scopes
The HIKMICRO Alpex 4K Lite combines exceptional image clarity, true close-range focus, lightweight handling and smart functionality that simply outclasses everything else under £500.
Its ability to focus down to 2 metres is a true game-changer for indoor pest control, and the 450g weight keeps your air rifle flickable and responsive throughout long nights.
For total darkness inside farm buildings, pairing it with a good 850nm or 940nm IR illuminator unlocks its full 4K potential.
If you want unbeatable performance on a budget — without compromise — this is the smartest ratting optic you can buy.
