Best Rifle Scopes Under £100 for UK Shooters (2026)

Spending under £100 on a rifle scope in 2026 no longer means settling for a toy. Advances in multi-coated lens technology, improved turret machining and intense competition among Far-Eastern manufacturers have pushed optical quality at this price point to a level that would have been unthinkable a decade ago. Whether you are fitting out a spring-powered air rifle for plinking and pest control in the garden, mounting glass on a .22 LR for rabbit lamping, or adding a basic optic to a .223 for foxing on a budget, there are genuinely competent scopes available without breaking the bank. This guide cuts through the marketing noise and tells you exactly what to look for.

The UK market has its own quirks that generic American buying guides ignore entirely. Our most popular discipline at this price bracket is sub-12 ft/lb air-rifle shooting, where ranges rarely exceed 50 yards and recoil from a spring or gas-ram powerplant is uniquely punishing on optics — the harsh bi-directional jolt kills scopes that survive centrefire recoil perfectly well. Then there is the legal landscape: you need to hold a valid firearms certificate for anything above air-rifle power, and many UK shooters start with an air rifle before moving up. Understanding these factors is crucial to choosing the right scope.

Within the sub-£100 bracket you will find scopes ranging from 3–9×40 variables suited to air-rifle hunters, through compact 4×32 fixed-power models ideal for rimfire, to surprisingly capable 3–12×40 or 4–16×44 designs that can sit on a centrefire rifle for medium-range work. The key decision factors are magnification range, objective lens size, reticle type (mil-dot, duplex, or BDC), turret style, and whether the scope uses a first focal plane (FFP) or second focal plane (SFP) reticle — each of which we explain in depth below.

We have evaluated the current UK market — including stock from retailers like Uttings, Pellpax, John Rothery, and the major online dealers — to identify the scopes that deliver the best combination of optical clarity, mechanical reliability and value. Below you will find our curated picks, followed by detailed buying advice that covers every specification you need to understand, common pitfalls to avoid, and how to match a scope to your specific shooting discipline. Whether you are a newcomer buying your first optic or a seasoned shooter fitting a budget spare, this is the definitive resource.

Buying Advice

Start with the specifications that actually matter at this price. Magnification is often over-prioritised: for sub-12 ft/lb air rifles effective to around 50 yards, 3–9× is more than enough, and a fixed 4× or 6× keeps things simple and robust. Objective lens diameter determines light-gathering ability — a 40mm objective is the sweet spot under £100, offering a good exit pupil at moderate magnifications without being excessively heavy or requiring ultra-high mounts. Pay close attention to eye relief: anything under 70mm is uncomfortable on a springer and potentially dangerous on a centrefire rifle. Fully multi-coated lenses (all air-to-glass surfaces coated) will noticeably outperform merely 'coated' optics in low light, which is critical for UK dawn and dusk shooting.

At the budget end — roughly £25 to £50 — you will find simple 4×32 or 3–9×40 scopes with wire-erector reticles and basic coatings. These are perfectly serviceable for casual plinking and garden-range air-rifle use to 30 yards, but expect some chromatic aberration, softer edge clarity, and turrets that may not track with perfect repeatability. In the £50 to £75 mid tier, optical quality jumps noticeably: expect fully multi-coated lenses, crisper reticles (often glass-etched), and more reliable turret adjustments — usually ¼ MOA per click, where 1 MOA equates to approximately 1.047 inches at 100 yards or roughly 3cm at 100 metres. At the £75 to £100 premium-budget tier, you start to see features like adjustable parallax (sometimes called an AO or side-focus), illuminated reticles, and occasionally even mil-based turrets offering 0.1 MRAD clicks, where each click moves the point of impact 1cm at 100 metres.

The most common mistake UK buyers make at this price is choosing too much magnification. A 6–24×50 scope for £60 sounds impressive on paper, but the optical compromises required to hit that price — poor lens coatings, imprecise erector systems, narrow eye boxes — make it worse in practice than a well-made 3–9×40 at the same money. Another frequent error is mounting a standard scope on a spring-powered air rifle without checking it is rated for the reverse recoil impulse. Springers and gas-ram guns recoil backwards then snap forwards, and this double-shuffle destroys scopes designed only for rearward recoil. Always confirm the manufacturer rates the scope as spring-piston safe, or budget for a separate damper mount. Finally, do not ignore mount height: UK air rifles with dovetail rails often need medium or high mounts to clear the breech or loading port, and getting this wrong leads to an inability to achieve a comfortable cheek weld.

UK-specific context matters enormously. For sub-12 ft/lb air rifles — which require no licence in England, Wales, and Scotland (though Scotland mandates an air weapon certificate) — effective hunting range is realistically 40 to 50 yards maximum, and a scope's holdover marks beyond that distance are largely irrelevant. For .22 LR rimfire, which requires a firearms certificate, shots on quarry rarely exceed 100 yards, making a basic 3–9×40 with a duplex reticle more than adequate. If you are putting a budget optic on a centrefire rifle such as a .223 Remington or .243 Winchester for foxing, be realistic about limitations: a sub-£100 scope will work at moderate ranges, but turret tracking, repeatability and optical resolution will not match a £300-plus optic for precision work. Buy from established UK retailers who offer returns and warranty support — high-street and reputable online dealers typically stock Hawke, MTC, Nikko Stirling, BSA, and Discovery, all of which have UK service centres or distributors.

Matching the scope to your use case is the single most important step. For HFT (Hunter Field Target) competition with an air rifle, you want an adjustable-parallax scope — parallax error at short distances can shift your point of impact by several millimetres, which matters in a discipline scored on small kill zones. For ratting with a rimfire at close range in poor light, prioritise a wide exit pupil and fully multi-coated glass over high magnification. For a centrefire foxing rifle on a tight budget, look for a scope with an exposed or at least finger-adjustable elevation turret so you can make field corrections without a coin or screwdriver. If you intend to use night-vision add-ons such as those from Pard, ensure the scope's eyepiece dimensions and eye relief are compatible with a clip-on device — some budget scopes have unusually small or recessed eyepieces that make this impractical.

The brand landscape under £100 in the UK is dominated by a handful of names. Hawke is arguably the most trusted, with their Vantage and Airmax lines sitting at or just above the £100 mark and occasionally dipping below on promotion. MTC Optics, a British-designed brand, offers the Viper and Mamba series with strong reputations for springer-safe construction. Nikko Stirling remains popular for entry-level scopes with a wide dealer network. BSA has a long heritage in the UK air-rifle market, and Discovery Optics has gained ground by offering FFP reticles and side-focus parallax at aggressive prices. Pard, primarily known for night-vision and thermal devices, is increasingly relevant if you are building a day-and-night capable setup on a budget — pairing a competent budget scope with a Pard NV clip-on is a cost-effective route to legal night shooting.
