A detailed guide to first focal plane rifle scopes — what to look for, which models to buy, and where to find the best UK prices
A first focal plane scope places the reticle at the front of the optical erector system. As you increase magnification, the reticle image grows proportionally with the target image — so your mil or MOA subtensions stay accurate at every power setting. Dial to 6x for a quick woodland shot or crank to 20x for a distant target: the reticle graduations hold true throughout.
This is the fundamental difference from second focal plane (SFP) designs, where the reticle appears the same size at all magnifications and subtensions are only accurate at one specific zoom (usually maximum). For UK shooters who engage targets at variable ranges without time to max out magnification, FFP delivers a genuine practical advantage.
A decade ago, FFP scopes were largely the preserve of military and law enforcement. Today they dominate precision shooting, PRS competition, and increasingly appear in deer stalking and foxing use. The reasons are straightforward:
Most serious FFP scopes use either a 30mm or 34mm main tube. A larger tube provides more internal elevation and windage travel — critical for long-range work where you might need 30–60 MOA of adjustment. If you are shooting beyond 600 metres, check the scope's total elevation adjustment before buying. 34mm scopes are heavier and require specific rings; for hunting or stalking use, 30mm is often a better balance of adjustment range versus weight.
The reticle is where FFP scopes differ most from each other. Key options in the UK market:
UK shooting conditions are often overcast, flat-lit, or happening at the edges of legal light. Glass quality matters enormously. Look for fully multi-coated lenses, ideally with ED (extra-low dispersion) glass that reduces chromatic aberration. A scope with a wide 44–56mm objective lens captures more light but adds weight — balance this against your intended use. For pure precision shooting, weight is acceptable; for a stalking rifle you carry over rough ground, every gram counts.
For tactical or precision use, exposed turrets with a zero stop are almost essential. Zero stop prevents you accidentally dialling below your zero in the field. Check the click value matches your reticle — if your reticle is in mils, get mil-click turrets. Mixing MOA turrets with a mil reticle (or vice versa) creates confusion under pressure. Quality clicks should be crisp, audible, and return to zero consistently.
Match the zoom range to your shooting:
One of the best-value FFP scopes available in the UK. The Athlon Argos BTR Gen 2 gives you proper zero-stop exposed turrets, mil-based reticle and clicks, and surprisingly capable glass for the price. Parallax adjustment, illuminated reticle, and a solid build quality make this genuinely usable on a precision rifle rather than just entry-level. Widely available from UK dealers including Brownells UK and Sportsman Gun Centre.
Hawke is a British-heritage brand with strong UK dealer support and excellent customer service. The Sidewinder 30 SF FFP offers a clean AMX or Mil Dot reticle in the first focal plane, side parallax for quick focus adjustments, and good low-light performance. Strong choice for UK hunters and field shooters who want an FFP optic without specialist import hassle.
Element Optics is a UK-founded brand that has disrupted the mid-range precision optics market significantly. The Titan 5-25x56 punches firmly into Vortex Viper PST territory at a lower price point, with genuinely excellent glass, crisp turrets, and a versatile APR-2D reticle. Zero stop is included, the build quality is excellent, and UK warranty support is straightforward. If you want serious precision FFP glass under £700, the Titan is the benchmark.
The Viper PST Gen II is a proven competition optic that appears on rifles at UK PRS and benchrest events regularly. Vortex's unlimited lifetime warranty — no receipt needed, no fault required — is a genuine selling point for UK buyers. The glass is sharp and high-contrast, the EBR-7C (MRAD) reticle is well-designed for holdovers, and the 30mm tube keeps weight reasonable. Available from Brownells UK and other major UK retailers.
Nightforce scopes are built to military specification tolerances and are used by competitors at the highest level of PRS globally, including UK Championships. The NX8 4-32x offers a remarkable zoom ratio in a relatively compact package. The glass is outstanding in all conditions, turrets are bombproof, and the daylight-bright illumination is genuinely useful. Overkill for most applications, but for serious long-range competitors this represents genuine value for the performance delivered.
| Situation | Recommended | Reason |
|---|---|---|
| PRS / precision rifle competition | FFP | Accurate subtensions at any zoom during timed stages |
| Deer stalking (woodland, short shots) | Either | Shots often close range at fixed zoom — SFP fine |
| Deer stalking (open ground, varied ranges) | FFP | Range estimation and holdover valid at any zoom |
| Fox / vermin control | FFP | Variable ranges, often no time to adjust magnification |
| Benchrest / fixed distance target shooting | SFP often preferred | Finer reticle at high magnification, no size change |
| Under £200 budget | SFP | Few quality FFP scopes exist at this price point |
Major UK retailers stocking a wide range of FFP scopes include Uttings, Sportsman Gun Centre, Brownells UK, Fifer Shooting, Anglo Arms, and Optics Warehouse. Prices vary between retailers — sometimes by £50–£150 on the same model. Use Scope Finder to compare live prices across all these retailers in one place before buying.
When buying, confirm: UK warranty support, whether VAT is included in the displayed price, and lead times for out-of-stock items. Some premium brands (Kahles, Schmidt & Bender, March) have longer lead times through UK dealers.

Find Your Scope on Scope Finder →An FFP scope places the reticle in the first focal plane so that the reticle subtensions (mil or MOA markings) remain accurate at every magnification setting. This differs from SFP scopes where accuracy is only guaranteed at maximum zoom.
For open-ground deer stalking at variable ranges, FFP gives you accurate mil or MOA readings without maxing out magnification first. For woodland stalking at short, predictable ranges, an SFP scope with a cleaner low-power reticle can be equally effective. Both work; FFP gives more flexibility.
For most UK long-range precision use, a 4-20x or 5-25x covers the range from positional close-range work out to 800–1000m steel. For hunting and stalking, a 2-12x or 3-18x is more practical. For competition PRS, 5-25x or 6-36x is common.
The Athlon Argos BTR Gen 2 (~£320) and Hawke Sidewinder 30 SF FFP (~£380) are the standout choices under £500. Both offer proper zero-stop turrets, mil-based reticle and clicks, and side parallax — features often absent from budget scopes.
Most FFP scopes are not optimised for air rifles. They often have minimum parallax set at 50–100m rather than 10–30m, and are not spring-recoil rated. Look for scopes specifically designed for air rifles — brands like Hawke Airmax and MTC Viper offer air-rifle-specific FFP models.
Generally yes — FFP scopes tend to be heavier due to their more complex optical erector design and typically larger tubes (34mm vs 30mm is common). Budget an extra 200–400g for a full-spec FFP precision scope versus an equivalent SFP hunting scope. For a stalking rifle you carry all day, weight is a genuine consideration.
Major UK stockists include Uttings, Sportsman Gun Centre, Brownells UK, Fifer Shooting, Anglo Arms, and Optics Warehouse. Use Scope Finder to compare live prices across these retailers — prices on the same model can vary by £100 or more.
The Athlon Argos BTR Gen 2 6-24x50 FFP (~£320) is an outstanding starting point. It includes zero stop, MRAD turrets matching a mil reticle, illumination, and side parallax — everything you need to start PRS training without compromising fundamentals with an inadequate optic.
