Calibres, FAC Power Output, and Accessories for the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock
The Air Arms S510 XS Ultimate Sporter FAC Walnut Stock stands out as a versatile high-power pre-charged pneumatic platform, and understanding its calibre options, FAC-level performance, and supporting accessories helps shooters select the ideal setup for hunting, pest control, or precision work. This section explores these key elements in detail so you can match the rifle to your needs and maximise its potential in the field or on the range.
Available Calibres and Their Practical Strengths

Air Arms offers the S510 XS Ultimate Sporter FAC Walnut Stock in three popular calibres: .177 (4.5 mm), .22 (5.5 mm), and .25 (6.35 mm). Each option suits different priorities while sharing the same regulated action, Lothar Walther barrel, and ambidextrous walnut stock.
The .177 calibre delivers a flatter trajectory and higher velocity, making it an excellent choice for target shooting, longer-range pest control, and situations where precision placement matters most. Shooters often favour this option when they want minimal holdover at extended distances. In contrast, the .22 calibre strikes a widely preferred balance between velocity, energy, and pellet availability. It provides reliable impact for small game and vermin while remaining highly accurate, which explains why many hunters and recreational shooters select it as their everyday workhorse. Meanwhile, the .25 calibre prioritises knockdown power and energy transfer. This larger option shines for bigger pests or situations that demand greater terminal effect at moderate ranges.
Furthermore, the 10-shot rotary magazines work across all three calibres, and two magazines come standard with the rifle. Therefore, switching between calibres (where legal and practical) or simply stocking spare magazines becomes straightforward. As a result, the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock adapts readily to changing conditions and preferences without requiring a completely different platform.
Understanding FAC Power Levels and Performance
FAC designation indicates a full-power version that exceeds the typical UK 12 ft-lb limit, delivering substantially higher muzzle energy suitable for more demanding hunting applications. On the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock, the regulated system produces approximately 20 ft-lbs in .177, 32 ft-lbs in .22, and 44 ft-lbs in .25. Corresponding velocities reach up to around 1035 fps in .177, 950 fps in .22, and 815 fps in .25, depending on pellet weight and exact power setting.
The built-in adjustable power dial lets you fine-tune output to balance energy, shot count, and consistency. Consequently, you can dial back power for quieter backyard or range sessions and increase it for field use. The fully regulated 186 cc air cylinder (in the standard XS Ultimate Sporter FAC configuration) supports solid shot strings—typically around 40–44 usable shots in .177, 35–40 in .22, and 30–35 in .25 at higher power settings—with minimal velocity variation until the regulator threshold. Fill pressure stands at 250 bar (3,626 psi), and the onboard manometer provides clear visual feedback so you know when to refill.
In addition, the integral Q-Tec moderator and fully shrouded barrel keep the report moderate even at FAC power levels. This quieter operation benefits both hunters who need discretion and shooters who simply prefer a more pleasant experience. Overall, the combination of adjustable power, regulation, and match-grade barrel delivers the consistency and authority that define the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock.
Standard Inclusions and Recommended Accessories
Every Air Arms S510 XS Ultimate Sporter FAC Walnut Stock arrives ready for use with a practical set of essentials. The package includes two 10-shot rotary magazines, four hex wrenches for adjustments, a fill adapter, and airgun oil. These items cover the basics of loading, maintenance, and air filling from the start.
Beyond the factory inclusions, the rifle’s design encourages further customisation. An accessory rail under the forend accepts bipods, palm rests, or other attachments, while integrated sling swivel mounts support comfortable carry during long days afield. The 11 mm dovetail rail on top readily accepts a wide range of scopes and mounts; many owners pair the rifle with side-focus or adjustable-objective optics in the 3–12x or 4–16x range for versatile performance from close to medium distances.
Additional popular accessories include spare magazines (colour-coded or calibre-specific for quick identification), a quality hand pump or high-pressure air tank for convenient refills, and a soft or hard case for transport and storage. Some shooters add a laser or torch for low-light work, while others fit a bipod for stable prone or rest shooting. Because the stock already offers an adjustable cheekpiece and buttpad, most users need only modest further customisation to achieve a personalised fit.
Moreover, the protective 20-micron filter built into the system helps keep internal components clean, reducing the need for frequent deep maintenance. When you do service the rifle, the supplied tools and straightforward design keep the process accessible. Therefore, the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock remains practical both as a ready-to-shoot package and as a platform that grows with your requirements.
Matching Calibre, Power, and Accessories to Your Needs
Choosing the right calibre depends on your primary use. Opt for .177 when trajectory and precision rank highest, select .22 for versatile all-round capability, or go with .25 when maximum energy takes priority. Pair any of these with the adjustable power system to refine performance further, and complete the setup with optics, a bipod, and spare magazines that match your typical shooting style. In this way, the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock transforms from a highly capable rifle into a fully tailored tool that supports consistent success across different scenarios.
By carefully considering calibre characteristics, FAC power delivery, and complementary accessories, you unlock the full potential of this refined pre-charged pneumatic rifle and enjoy years of accurate, powerful, and enjoyable shooting.
Frequently Asked Questions About the Air Arms S510 XS Ultimate Sporter FAC Walnut Stock
What calibres does this rifle come in, and which one should I choose?
This high-performance pre-charged pneumatic rifle is available in three proven calibres: .177, .22, and .25. Each option delivers distinct advantages depending on your primary use. The .177 calibre produces a flatter trajectory and higher velocity, which many shooters prefer for precise target work or longer-range pest control where holdover stays minimal. In contrast, the .22 calibre offers an excellent middle ground of speed, energy, and pellet selection, making it the most popular all-round choice for small-game hunting and general field use. Meanwhile, the .25 calibre prioritises terminal energy and knockdown power, suiting larger pests or situations that demand greater impact at moderate distances.
Your decision should also consider local regulations, typical engagement ranges, and preferred pellet weights. Furthermore, the same adjustable power system and regulated action support all three calibres, so you retain flexibility once you select a chambering. As a result, most owners find that matching calibre to their most frequent shooting scenarios produces the best long-term satisfaction.
What does FAC mean, and how does it affect performance?
FAC indicates a full-power configuration that exceeds the standard 12 ft-lb limit common in certain regions. This version generates substantially higher muzzle energy—approximately 20 ft-lbs in .177, 32 ft-lbs in .22, and 44 ft-lbs in .25—while still maintaining the accuracy and consistency expected from a premium regulated platform. Corresponding velocities typically reach around 1035 fps in .177, 950 fps in .22, and 815 fps in .25, depending on pellet choice and power setting.
The higher output expands effective range and terminal performance for hunting and pest control. At the same time, the built-in power adjuster allows you to reduce output when quieter or lower-energy shooting is preferred. Therefore, the FAC designation provides both capability and versatility rather than locking you into maximum power at all times. Always check local laws regarding ownership and use of full-power air rifles before purchasing.
How many shots can I expect per fill, and is the system regulated?
Yes, the action is fully regulated, which delivers far more consistent velocity across the shot string compared with unregulated designs. With the standard cylinder capacity on this model, you can typically expect around 40–44 usable shots in .177, 35–40 in .22, and 30–35 in .25 when running at higher power settings. Lowering the power dial increases the shot count further while preserving accuracy.
The regulator maintains stable output until pressure drops near the set threshold, after which velocity begins to decline. Monitoring the built-in manometer and refilling at the recommended pressure keeps every magazine performing reliably. In addition, the 250-bar fill pressure and protective filter help protect the system during regular use. Consequently, most shooters enjoy predictable performance throughout a full outing without constant velocity checks
What is included with the rifle, and what accessories work well with it?
Each rifle ships with two 10-shot rotary magazines, a set of hex wrenches, a fill adapter, and airgun oil. These items cover immediate loading, basic adjustments, and air-filling needs. The ambidextrous walnut stock already features an adjustable cheekpiece, adjustable rubber buttpad, checkered grip and forend, integrated sling mounts, and an accessory rail under the forend.
Popular additions include a quality scope mounted on the 11 mm dovetail rail—many owners favour side-focus models in the 3–12x or 4–16x range for versatile field and range work. A bipod or palm rest attaches easily to the under-forend rail for stable shooting positions. Spare magazines, a high-pressure air tank or hand pump, a soft or hard case, and a simple sling further enhance practicality. Because the stock and action are already highly adjustable, most users need only a few well-chosen accessories to create a complete, personalised setup.
How accurate is this rifle, and what contributes to its precision?
The combination of a match-grade Lothar Walther barrel, fully regulated air delivery, and a crisp two-stage adjustable trigger produces excellent real-world accuracy. Many owners report tight groups at 30–50 yards and usable precision well beyond that distance when using quality pellets matched to the individual barrel. The integral moderator and shroud also reduce muzzle disturbance, supporting consistent shot placement.
Proper pellet selection, a solid rest or bipod, and a correctly mounted optic further improve results. In addition, the adjustable stock allows you to achieve a stable, repeatable cheek weld and length of pull, which directly benefits group size. Therefore, the platform rewards careful setup and practice with reliable, repeatable performance suitable for both hunting and target work.
Is the stock truly ambidextrous, and how adjustable is it?
Yes, the walnut stock is fully ambidextrous, so left- and right-handed shooters can use the rifle without modification. The adjustable cheekpiece and rubber buttpad let you fine-tune comb height and length of pull for a comfortable, consistent fit. Checkering on the grip and forend improves control in varied weather, while the overall ergonomics support extended sessions without fatigue.
These features make the rifle inclusive for shooters of different sizes and preferences. Moreover, the ability to customise the fit quickly reduces the need for aftermarket stock work. As a result, most users achieve an excellent shooting position right out of the box and maintain it across different positions and distances.
How quiet is the rifle, and does the moderator make a noticeable difference?
The fully shrouded barrel and permanently affixed Q-Tec moderator significantly reduce muzzle report compared with unshrouded high-power designs. While no FAC-power air rifle is completely silent, the combination keeps the sound at a moderate, field-friendly level that many hunters find practical for discreet use. The moderator also helps smooth the shot cycle and can contribute to slightly tighter groups by minimising barrel vibration.
Shooters who prioritise noise control often pair the rifle with heavier pellets and a slightly reduced power setting for even quieter operation. Consequently, the moderated design expands the environments in which the rifle remains enjoyable and effective.
What maintenance does the rifle require, and how durable is it?
Routine care is straightforward. Keep the exterior clean, apply a light coat of oil to metal surfaces when needed, and protect the walnut stock from prolonged moisture. The internal 20-micron filter helps keep contaminants out of the valve and regulator, reducing the frequency of deeper servicing. Periodically check the magazines for smooth rotation and inspect the fill probe and seals.
Air Arms builds these rifles with high-quality components and attention to detail, so they typically deliver years of reliable service when treated with basic care. The lifetime limited warranty offered by many retailers further reflects confidence in the construction. Therefore, most owners find that simple, regular attention keeps the rifle performing at its best.
Can I adjust the power, and how does that work in practice?
Yes, an external power dial allows easy adjustment without tools. Turning the dial alters the amount of air released for each shot, letting you trade energy for additional shots or quieter operation. The regulator keeps velocity consistent within each setting, so groups remain tight even when you change power levels.
Many shooters develop preferred settings for different pellets or distances and simply return to those positions as needed. In addition, the manometer provides clear feedback so you always know the remaining pressure. This flexibility makes the rifle adaptable to changing conditions without compromising the core accuracy of the platform.
Is this rifle suitable for both hunting and target shooting?
Absolutely. The combination of FAC power, regulated consistency, adjustable stock, and quiet moderated barrel makes the rifle equally at home in the field and on the range. Hunters appreciate the energy levels, shot count, and discreet report for pest control and small-game pursuits. Target and recreational shooters value the trigger, barrel quality, and ability to dial power for different distances or pellet types.
The ambidextrous, highly adjustable stock further supports comfortable use across varied positions and session lengths. Consequently, one well-chosen caliber and a suitable optic often cover both roles effectively, delivering excellent value for shooters who enjoy multiple disciplines.
What should I know about filling and air management?
The rifle fills to 250 bar (approximately 3,626 psi) via the included adapter. A quality hand pump, compressor, or high-pressure tank all work well. Always follow safe filling practices, monitor the onboard gauge, and avoid overfilling. The regulator ensures that usable shots remain consistent until pressure approaches the set threshold, at which point velocity begins to drop.
Refilling before the pressure falls too low maintains peak performance. In practice, most owners develop a simple routine of checking the gauge after a set number of magazines and topping up as needed. This approach keeps every outing productive and enjoyable.
How does the trigger feel, and can I adjust it?
The two-stage adjustable trigger delivers a crisp, predictable break that many describe as match-like. You can fine-tune both stages to suit personal preference, which helps refine shot release and overall accuracy. The manual safety provides positive control when needed.
Because the trigger is already of high quality from the factory, most shooters make only minor adjustments before settling on a preferred setting. Combined with the stable stock and precise barrel, the trigger contributes significantly to the rifle’s reputation for repeatable performance.
Are there any legal considerations I should keep in mind?
Power levels and ownership rules vary by country and region. In some areas the FAC designation requires specific certification or registration, while elsewhere the same rifle may be freely available. Always verify local airguns laws regarding muzzle energy, transportation, storage, and permitted uses before purchase or use. Responsible ownership includes safe handling, secure storage, and awareness of where and how you may shoot.
Choosing quality pellets, practicing regularly, and respecting both the equipment and the environment further support safe, enjoyable use for years to come.
These answers cover the most common questions about performance, features, and practical ownership. The combination of caliber choice, adjustable regulated power, refined ergonomics, and thoughtful accessories makes this rifle a capable and adaptable platform for a wide range of shooters. When you match the setup to your preferred caliber and typical shooting conditions, you gain a reliable partner for accurate, powerful, and satisfying sessions in the field or on the range.
Practical Use Scenarios
Imagine stepping into the early morning light with a refined pre-charged pneumatic rifle that balances power, precision, and comfort. Whether you pursue small game, manage pests around farmland, or refine your skills on the range, this regulated sidelever platform adapts smoothly to real-world demands. The ambidextrous walnut stock with adjustable cheekpiece and buttpad, combined with a match-grade barrel, integral moderator, and adjustable power, creates a tool that supports consistent results across varied conditions. The following scenarios illustrate how shooters put these strengths to work in everyday and specialised situations.
Early-Morning Pest Control on Mixed Terrain
Many owners begin their day before sunrise, moving quietly along hedgerows or field edges where rabbits and similar pests become active. The moderated barrel and shroud keep the report subdued, allowing multiple opportunities without scattering nearby animals. In .22 calibre, the roughly 32 ft-lb energy level delivers reliable terminal performance at typical engagement distances of 25 to 45 yards, while the regulated action maintains velocity consistency so the first and last shots of a magazine land with similar impact.
Shooters often set the power dial a notch or two below maximum for a quieter cycle and extended shot count, then return to full output only when longer shots appear. The adjustable cheekpiece ensures a solid weld even when shifting between kneeling and supported positions, and the checkered forend provides secure control when gloves or damp conditions come into play. An under-forend rail accepts a lightweight bipod that deploys quickly on uneven ground, while the integrated sling mounts free the hands for scanning or carrying additional gear.
After a successful session, the built-in manometer shows remaining pressure at a glance, so a quick top-up from a compact tank or pump restores full capacity before the next outing. This combination of discretion, adjustable power, and ergonomic fit turns what could be a frustrating chase into a methodical and productive morning.
Midday Small-Game Hunting in Woodland
Later in the day the same rifle moves into denser cover where grey squirrels or similar quarry present brief windows of opportunity. Here the .25 calibre option shines for its higher energy transfer approximately 44 ft-lbs while the Lothar Walther barrel still delivers the accuracy needed for clean, ethical shots through light foliage. The sidelever cycles smoothly and quietly, allowing a second shot from the ten-round magazine if the first is disrupted by branches.
Shooters frequently pair the platform with a compact side-focus scope in the 4–12x range, mounted on the 11 mm rail, so parallax can be adjusted quickly for distances that shift from 15 to 40 yards. The adjustable buttpad helps maintain a consistent length of pull when leaning against a tree or shooting from a seated position on the forest floor. Because the stock is ambidextrous, left-handed hunters experience the same natural handling as right-handed ones, removing a common barrier to shared or family use.
Transitioning between open rides and thicker stands requires only a change in stance and perhaps a slight power adjustment. The regulated system keeps groups tight even as cylinder pressure declines, so confidence remains high throughout a multi-hour walk. At the end of the outing the protective filter has done its job, limiting the need for immediate deep cleaning and letting the focus stay on the day’s results rather than maintenance.
Afternoon Range Sessions and Skill Development
Not every outing centres on harvesting. Many shooters dedicate regular time to zero confirmation, pellet testing, and positional practice. On a formal or informal range the rifle’s crisp two-stage trigger and consistent regulator output reward careful technique. In .177 calibre the flatter trajectory and higher velocity simplify holdovers at 50 yards and beyond, making it ideal for group-size challenges or informal competitions among friends.
A typical session might begin with a full fill and the power dial set for maximum consistency. After confirming zero with a preferred pellet, the shooter works through supported prone, kneeling, and standing positions, using the adjustable cheekpiece to maintain the same eye alignment each time. The under-rail bipod or a simple rest provides stability during the precision phase, while removing it forces greater reliance on natural point of aim and trigger control.
Because the magazines index reliably, follow-up shots arrive quickly without breaking concentration. Transition words and careful observation of the manometer help the shooter learn exactly when velocity begins to taper, building an intuitive sense of air management. Over successive range days these habits transfer directly to field success, turning recreational practice into measurable improvement.
All-Day Mixed-Use Outings
Some of the most satisfying experiences combine elements of the previous scenarios into a single extended day. A shooter might start with early pest control near agricultural buildings, move into woodland for opportunistic small-game opportunities, then finish with a late-afternoon range session to verify equipment and technique. The same rifle, calibre, and optic handle the entire sequence because the adjustable power dial, moderated barrel, and ergonomic stock adapt to each environment.
Carrying the platform on a simple sling keeps both hands free for glassing or navigating obstacles. When a shot opportunity appears, the sidelever and magazine system allow rapid readiness without fumbling. The walnut stock’s checkering remains secure even after hours of handling, and the adjustable components maintain comfort as fatigue gradually increases. At the end of the day a single fill from a larger tank restores the cylinder, and a quick wipe-down of exterior surfaces prepares the rifle for the next use.
This flexibility reduces the need to own multiple specialised air rifles. One well-configured platform, supported by a modest selection of accessories extra magazines, a bipod, a quality scope, and a reliable air source covers the majority of practical requirements for most enthusiasts.

Tips for Maximising Real-World Results
Successful practical use rests on a few consistent habits. First, match pellet weight and design to the chosen caliber and typical distance; even a premium barrel benefits from systematic testing. Second, develop a personal power-setting chart so you can return to preferred combinations quickly. Third, practise air management by noting gauge readings after set numbers of shots, ensuring you never enter a critical moment with marginal pressure. Fourth, keep the stock adjustments locked once a comfortable fit is found, then re-check them only after significant changes in clothing or position.
Inclusive design features further broaden accessibility. The ambidextrous layout and wide adjustment range accommodate different body sizes and dominant hands, while the moderate weight and balanced feel reduce strain during long carries. Shooters who share equipment or introduce new participants to the sport often find these qualities particularly valuable.
Weather and terrain introduce additional variables. In damp conditions the checkered surfaces and moderated report remain advantages; in open windy fields the higher sectional density of heavier pellets in .22 or .25 can improve wind resistance. The regulated action continues to deliver predictable velocity across these changes, giving the shooter one less variable to manage.
From First Outing to Long-Term Partnership
New owners typically begin with familiarisation sessions that combine range time and short field walks. They learn the trigger break, magazine handling, and power dial in a controlled setting before applying those skills to live opportunities. Over subsequent months the rifle becomes an extension of the shooter’s own technique reliable enough for ethical harvests, precise enough for personal bests on paper, and comfortable enough for all-day use.
Accessories evolve with experience. Some shooters add a more special optic or a dedicated bipod; others simply refine their pellet choice and zero. The core platform remains unchanged because its fundamental strengths regulated consistency, adjustable ergonomics, quiet operation, and FAC-level capability already address the majority of practical demands.
Whether the goal is quiet early-morning pest management, ethical woodland hunting, deliberate range practice, or an integrated full-day adventure, the combination of features supports confident, effective shooting. By understanding how the adjustable power, moderated barrel, ambidextrous stock, and regulated action interact in real environments, every user can extract the full measure of performance the design offers and enjoy productive, satisfying time afield.
