Air Arms S510 Walnut

The Air Arms S510 XS Xtra FAC in walnut is a refined, purpose-built precharged pneumatic sporting rifle that blends pinpoint accuracy with handsome, high-end craftsmanship. Built in England and engineered for shooters who demand consistent group performance, the S510 XS Xtra features a fully regulated action and a generous 288 cc air cylinder that delivers stable, repeatable shots and more usable rounds per fill. Its sidelever cocking makes for fast, ergonomic operation while the 10-shot rotary magazine allows rapid follow-up shots without sacrificing the single-shot-level precision Air Arms is known for.

At the heart of the rifle is a match-grade Lothar Walther rifled barrel (rifled length ~19.75″), contained within a longer shroud for exceptionally quiet operation. The rifle’s exterior length from action to muzzle measures 24″, making the XS Xtra the full-size option that gives slightly more power and shot count versus the carbine variant. Power is user-tunable via a 5-position adjuster, and a built-in manometer plus 3,625 psi (250 bar) fill capability keep you informed and ready in the field.

Trigger control is class-leading: a 2-stage adjustable trigger provides a crisp, customizable break for both target shooters and hunters. Ergonomics are elevated with a beautifully checkered pistol grip and forearm, superb blued metalwork, ventilated rubber buttpad for recoil absorption, and machined 11mm scope grooves for optical mounting (this model omits open sights). Whether you’re pursuing small game, refining benchrest groups, or shooting long plinking sessions, the S510 XS Xtra FAC walnut stock balances stability, comfort, and timeless aesthetics.

In short: if you want a premium, regulated PCP repeater that pairs courtroom-level accuracy with a classic walnut finish and modern features — the Air Arms S510 XS Xtra FAC is an outstanding choice built to last.
