The Ultimate Sporter XS Xtra takes Air Arms' most prized PCP and adds even more value to a platform already at the height of its powers. With an introduction of a fully-regulated system, the Air Arms S510 XS is the S510 action perfected, with more shots per fill than ever before.

This variant features a finely crafted Walnut stock, with luxurious etching that reflects Air Arms dedication to traditional craftsmanship. This XS’s precision checkering on the grip and forend, fine curves and grooved handholds make this PCP a worthy mantlepiece. The Minelli stock comes complete with an adjustable, soft-touch coated cheekpiece, adjustable buttpad, integrated sling mounts, and an accessory rail ready to accept bipods or even a palm shelf.

Customers requested a regulated S510 and Air Arms delivered, all while boosting the power of the increasingly popular .25 caliber. With this regulated upgrade, the XS can achieve a whopping 44 ft-lbs in .25, 32 ft-lbs in .22 and 20 ft-lbs in .177. Power isn't the only thing increasing in the XS. The XS regulator offers increased consistency and shot counts from the 288cc cylinder, delivering an impressive 60 (.177), 55 (.22) and 40 (.25) shots per fill with minimal velocity change.  These long shot strings are further aided by a built-in power adjuster. Each XS Xtra features the prized Lothar Walther barrel, which gives this platform its renowned accuracy. Each rifle includes 2 of Air Arms perfected 10-shot indexing magazines, smooth side-lever cocking mechanism and an easy to read built-in manometer.

The Air Arms Ultimate Sporter platform has turned heads at the range since 2013 with shots so accurate they require a double-take. If you want the longest, most consistent shot strings with surgical accuracy, join the elite ranks of Air Arms airgunners with S510 Ultimate Sporter XS Xtra.
