The name invites scepticism. Calling anything "Ultimate" is a hostage to fortune, and plenty of manufacturers have been embarrassed by less. Yet the Air Arms Ultimate Sporter has carried the title for years without much argument from the people who own one. It takes the proven S510 sidelever action and wraps it in a fully adjustable laminate stock aimed at shooters who want sporter handling with target-rifle fit. This review looks at what that combination actually delivers, and who should pay the premium for it.
The concept
Most sporting air rifles ask you to adapt to them. The Ultimate Sporter reverses the deal. The cheekpiece adjusts for height, the butt pad adjusts for length and position, and the result is a rifle that can be set up to fit your face and shoulder precisely, the way a competition rifle fits, but in a package you would happily carry around a farm. Underneath, it is pure S510: the same silky sidelever, the same Lothar Walther barrel, the same ten-shot magazine and two-stage adjustable trigger. Current versions are available regulated, badged Ultimate Sporter R, and that is the one to have.
Fit and ergonomics
The laminate stock is the story here. Available in attractive multi-coloured or more sober grey-black laminates depending on batch and year, it is heavier and stiffer than walnut, and the extra mass settles the rifle noticeably on aim. The adjustable cheekpiece means your eye arrives behind the scope at exactly the same place every time you mount the rifle, and consistent head position is worth more to practical accuracy than most upgrades shooters spend money on. The grip is steep and target-styled, putting your trigger finger square onto the blade.
For hunting from sitting or kneeling positions, and for HFT where you take the same aim position shot after shot, the difference between this and a fixed-comb sporter is not subtle. Once it is set for you, it simply fits.
Performance
Everything said about the S510's accuracy applies, with the regulator sharpening the edges. Over a chronograph, a well-run Ultimate Sporter R produces velocity spreads in the single figures, and on paper that shows up as tight vertical dispersion at 40 yards and beyond. With Air Arms Diabolo Field pellets, sub-half-inch groups at 30 yards are routine, and skilled shots will better that. The trigger adjusts down to a crisp, light break that flatters careful shooting.
Shot count from the 250 bar fill is generous, expect broadly 100-plus consistent shots in .22 and somewhat fewer in .177, with the regulator keeping the power flat across the usable band rather than arcing up and down as unregulated rifles do. A shrouded barrel and factory moderator option keep it quiet enough for sensitive permissions.
Weight and handling
There is no free lunch: laminate and adjustability bring weight, and a scoped Ultimate Sporter with moderator will nudge past 4 kg. Shooters who cover serious miles on foot may prefer the standard walnut S510 or the lighter S400. But weight is a friend when the rifle is on aim, it damps wobble, absorbs the (already minimal) firing cycle, and makes long strings less tiring for the aim rather than more. For a rifle that spends its life shot from a knee, a bag or sticks, the mass is a feature.
Price and value
This is the most expensive sporter Air Arms makes, with regulated laminate examples typically listed around £1,300 to £1,400 new. Against that, consider what it replaces: many owners buy an Ultimate Sporter instead of running separate hunting and HFT rifles, because it does both jobs without compromise. Like all Air Arms rifles, it holds value stubbornly on the used market, and clean examples rarely hang around long when listed.
Ultimate Sporter vs the alternatives
Within the family, the standard S510 gives you the same action and accuracy in walnut for meaningfully less money the Ultimate Sporter's case rests entirely on the adjustable fit and laminate stability. The S510 Tactical offers adjustability through an AR-style synthetic stock at a lower price, trading traditional looks for modularity. Outside the family, the Weihrauch HW100 in thumbhole laminate is the natural rival: German precision against British balance, and a coin toss most buyers settle by handling both. The electronic Daystates offer more technology for more money; the Ultimate Sporter's appeal is that it achieves its consistency mechanically.
Verdict
The Ultimate Sporter is what happens when a manufacturer takes an already excellent rifle and removes the last excuses. It will not make a poor shot into a good one, but it removes the variables - fit, consistency, trigger - that stop good shots performing to their ability. If you shoot one rifle for everything and want that rifle to fit like it was made for you, this is among the very best sub-12 ft-lb rifles money can buy.
