Air Arms built its name on walnut, blued steel and a deliberately traditional idea of what a sporting airgun should look like. So when the Hailsham factory released the S510 Tactical, its flagship action dressed in a black, adjustable, AR-inspired synthetic stock, it raised eyebrows among the faithful. A few years on, the Tactical has quietly become one of the most popular rifles in the range, particularly with younger shooters and pest controllers. This review looks at what changes, what doesn't, and whether the modern dress suits the classic action.
Same action, different philosophy
Strip away the furniture and the S510 Tactical is a standard S510: the same silky sidelever, ten-shot indexing magazine, Lothar Walther barrel, shrouded muzzle, adjustable two-stage trigger and 250 bar cylinder, in .177 or .22 at sub-12 ft-lb with FAC options for certificate holders. Regulated versions carry the familiar R designation. Everything that makes the S510 one of Britain's best PCPs is present and unchanged.
What changes is everything you touch. The synthetic tactical stock brings an adjustable cheekpiece, an adjustable butt pad, a vertical pistol grip, and moulded rails and QD points for accessories. Where the walnut S510 asks you to fit yourself to a beautifully shaped but fixed stock, the Tactical adjusts to fit you, the same philosophy as the laminate Ultimate Sporter, delivered in a lighter, weatherproof and less expensive package.
Handling and practicality
Synthetic stocks earn their keep in the field. The Tactical shrugs off rain, mud and knocks that would leave marks on walnut a shooter would grieve over, and the textured surfaces stay grippy with cold or wet hands. The vertical grip puts the trigger finger at a natural angle for shooting from sticks, bipod or bench, and the adjustable comb means your eye lands behind the scope identically every time, a real accuracy aid at longer ranges.
Weight sits close to the standard rifle's, and the balance remains centred despite the different architecture. Pest controllers who shoot from vehicles, barns and awkward positions particularly rate the format: this is a rifle designed to be used hard rather than admired.
Performance
There is nothing new to say about the shooting, which is the highest compliment. The S510 action delivers the same effortless accuracy in tactical dress as it does in walnut, expect sub-half-inch groups at 30 yards with quality pellets such as Air Arms Diabolo Field, generous shot counts from the 250 bar fill, and single-figure velocity spreads from regulated examples. The shrouded barrel keeps the report modest, and with a moderator fitted the rifle is impressively quiet for close-quarters farmyard work.
The trigger deserves its own mention: the same adjustable two-stage unit as the rest of the sporter range, breaking cleanly and predictably. Plenty of tactical-styled rifles from other makers pair aggressive looks with indifferent triggers; this one shoots as seriously as it looks.
Tactical vs Walnut vs Ultimate Sporter
Choosing within the S510 family comes down to taste and use. The walnut S510 is the traditionalist's rifle and the best-looking of the three. The Ultimate Sporter offers the most refined adjustable fit with laminate stability, at the highest price. The Tactical delivers most of the Ultimate Sporter's adjustability at a friendlier price, with the toughest, most weatherproof furniture of the three, typically listing somewhat below the laminate flagship. For a working rifle that lives in a truck cab and earns its keep in all weathers, the Tactical is arguably the most sensible S510 of all.
The competition
The obvious rivals are the adjustable synthetic PCPs from FX, Brocock and Daystate. Against them, the Air Arms plays its usual cards: a mechanically simple, proven action with nothing electronic to fail, British manufacture with factory service in East Sussex, and resale values that stay stubbornly high. What it gives away is modularity; it does not offer the calibre-swapping, tune-anything flexibility of an FX, but many shooters see fewer adjustments as a feature rather than a limitation.
Verdict
The S510 Tactical answers a question plenty of shooters were asking: can I have Air Arms quality without the walnut, at a working rifle's price, with a stock that adjusts to fit? Yes. It keeps every mechanical virtue of the flagship S510 and adds practicality that traditional furniture cannot match. The purists can keep their walnut — the Tactical is the S510 for shooters who measure a rifle by what it does, not what it is dressed in.
