Have a few Air Arm rifles and bits and they are all brilliant. Have also had contact with a few people there (Louis and others) and they have always been helpful and knowledgeable. Brilliant company.

I’ve both owned and sold hundreds of Air Arms products as an RFD and their reliability and practical performance are second to none on the market, and followed by a five-star warranty it’s hard not to be impressed by them as a company.

Why Shooters Choose the S400
Straightforward Precision
With its single-shot format and bolt-action design, the S400 puts you fully in control of every shot. No distractions, no unnecessary mechanics – just you, the rifle, and the target. It’s ideal for learning proper form, mastering technique, and building the discipline that leads to true precision over time.
Extended Shooting Sessions, Less Hassle
A long air cylinder means more shots per fill, so you can enjoy longer, uninterrupted sessions without constantly stopping to refill. This efficiency helps you stay focused and in rhythm, giving you more time to practice and refine your skills without breaking momentum.
Comfort Meets Control
Designed with an ergonomic, well-balanced stock, the S400 feels comfortable and natural in your hands, reducing fatigue even over extended use. The result? Greater control, better follow-through, and a smoother shooting experience that lets you stay focused from first shot to last.
Action
Bolt-Action Simplicity
Every S400 features Air Arms’ classic bolt-action system for manual loading and cocking. Smooth, intuitive, and reliable, this action gives you full control over each shot. It’s ideal for beginners learning proper form and experienced shooters who value a hands-on, deliberate approach to precision shooting.
Calibre
.177 – Precision & Flat Trajectory
Ideal for target shooting or pest control at longer distances. Delivers higher velocity and a flatter flight path, helping you achieve tight, repeatable groupings.
.22 – Balanced Impact & Versatility
Offers more stopping power while maintaining strong accuracy and a solid shot count. A versatile choice for mixed shooting needs, from targets to small game.
Simple and Reliable Performance
Unregulated Design, Low-Maintenance Shooting
The S400 is unregulated by design, meaning fewer internal components and a straightforward power system. This simplicity reduces maintenance, improves reliability, and makes it a great choice for shooters who prefer hassle-free performance without sacrificing consistency.
