Air rifle featuring a rifled barrel in caliber 4.5 mm, categorized among highly advanced Pre-Charged Pneumatic (PCP) models. Engineered by the renowned British manufacturer Air Arms.
A 494 mm barrel length guarantees tight shot grouping, especially at extended ranges beyond 80 meters. Manufactured by the German Lothar Walther facility, its rifled barrel incorporates 12-groove rifling with a 450 mm twist rate and features a choked muzzle for improved accuracy.
The barrel is deeply integrated into the action with an enhanced eight-point mounting system, preventing any micro-tilting relative to the intended bore axis—an essential feature to avoid errors in bullet drop and wind drift calculations during long-distance shooting.
The air cylinder is replenished via a specialized manual or electric pump, or with a scuba cylinder. A dedicated adapter is included to facilitate both filling methods. When fully charged, the compressed air tank delivers up to 100 shots. An integrated manometer allows continuous monitoring of tank pressure.
ATTENTION PCP air rifles require a high-pressure air source for charging. - Filling can be accomplished with a diving cylinder, transferred using a PCP charging kit. - Alternatively, charging can be performed with a pump.
Only dry air should be introduced into the rifle’s tank to prevent internal corrosion. The tank should always maintain about 30 BAR of pressure to facilitate self-sealing.
For safety of both the user and the rifle, the cylinder automatically vents if the maximum fill pressure of 250 BAR is exceeded, releasing excess compressed air safely. It remains crucial not to surpass the maximum allowed pressure, as excessive pressure may cause irreversible damage under extreme conditions.
Pellet loading is simple: pull back the bolt handle to open the loading port, place a pellet on the groove, and push the handle forward. This action chambers the pellet and prepares the rifle for firing, similar to the operation of a rimfire firearm.
Mechanical sights are not fitted, but a two-piece 11 mm standard mounting rail allows for easy scope attachment.
Hand-crafted forearm ensures a secure grip, while the rubber recoil pad provides added comfort. The Monte Carlo style stock is ergonomically contoured for optimum cheek support.
The trigger offers a light, crisp action and, with adjustable pull length and resistance, can be tailored to individual preferences. A straightforward trigger safety mechanism ensures secure handling. Light weight (2.72 kg) facilitates accurate aiming without fatigue.
The stock is crafted from a single wood blank, reminiscent of premium hunting rifles.
Outstanding manufacturing quality, power, absence of recoil, and superior precision make shooting with this air rifle an exceptional experience.

Militaria.pl is the exclusive distributor of Air Arms
Air Arms is a British brand operating since 1983, specializing in the production of spring and PCP air rifles. The company quickly gained recognition thanks to the TX200 model, which is still considered one of the best spring air rifles in the world. A distinctive feature of the brand is the use of cold-rolled barrels and precision adjustable trigger mechanisms. Air Arms was one of the first companies to introduce a multi-shot magazine system for PCP air rifles, which significantly increased the comfort and speed of shooting. The brand is associated with award-winning shooters such as Andy Calpin, a legend in the Field Target discipline, and James Osborne, a multiple champion and representative of the world's elite. Series such as the S400, S410, Pro Sport, and HFT 500 are recognized worldwide.
A few years ago I had one and I came back to it again. I also have another one in a similar price range but the s400f is great. The other one is set aside for now. If you're looking for a good PCP in this price range, you won't find a better one. Of course, that's my opinion.

Air Arms did not disappoint, I am extremely satisfied with the equipment. Accuracy and repeatability are exactly what I expected from the air rifle, and that's what I got. The rifle is light, which is a big plus; your arm doesn't get tired when shooting standing, so you can do a longer training session. I recommend this equipment because it's worth it, really worth it.

Great equipment. After a few more expensive air rifles, I gladly come back to the s400. There are many good things to say about this model. I'll just say this; if you want to have an accurate and well-made air rifle for a reasonable price, the s400/s410 is for you. It is also not picky about pellets. The lack of a regulator does not bother either.

For a few days I have been a happy owner of the Air Arms S400F and what can I say, I am very pleased that I finally decided to buy it. The accuracy of the carbine is phenomenal — at 30 meters it cuts out half a grosz coin, and the number of shots per cartridge between 190-100 bar is 110 with a tolerance of +,-4 m/s, so exactly consistent (confirmed with a chronograph). I can wholeheartedly recommend this equipment.

Very nice PCP, at 60 meters you can easily group shots within a 2-zloty coin. Mine shoots best with JSB 4.50. I have shot at slightly larger targets even at 100m in good weather conditions.

A masterpiece. The stock is beautiful! The wood engraving looks fabulous. The carbine is very light (with a Hawke Vantage 6-24 scope) compared to the HW97KT Black (with a Vortex Crossfire 6-18 scope). The trigger works perfectly. The cheek piece is ideally suited for high mounting. Shoulder the rifle to shoot literally takes a second. The look of the whole carbine is sheer perfection. It shoots devilishly accurately. There's a reason it's called a legend! I recommend it to anyone who has a springer and wants to try and own a PCP.

The air rifle is very carefully and aesthetically, nobly made. Excellent accuracy. Regarding rate of fire, apparently the reviewer had in mind their own manual skills, as reloading here is manual. Using this equipment is a real pleasure and an incentive to practice shooting sports.

The carbine is a classic. Beautifully crafted with attention to detail, a beauty typical of English rifles, the bluing shimmers in the sun although it is a bit delicate. Everything is refined visually and mechanically, you can shoot accurately with this carbine straight out of the box without needing a tune-up. At this price, the most reasonable PCP choice. Using it is pure pleasure!!!

The best PCP rifle for this money. Incredible accuracy as well as beauty and ergonomics. Large cartridge capacity, which is an advantage. The S400 wins competitions against much more expensive machines. The four-stroke bolt and the fact that the rifle is single-shot are further advantages. With a clear conscience I don't even hesitate—get the S400.
