AIR ARMS S400 .177 VERY GOOD CONDITION W/SCOPE

Air Arms S400 .177 – Very Good Condition – With Scope – £400

A superb opportunity to own a premium British-built pre-charged pneumatic air rifle: the Air Arms S400 in .177 calibre. This example is presented in very good condition, complete with scope, and priced attractively at £400.

Features & Highlights:

• Calibre: .177 — convenient for target shooting as well as lighter pest work.
• Bolt-action, single shot; classic design for precision and consistency.  
• Built-in manometer so you can monitor remaining air pressure — part of the excellent engineering.  
• Premium stock (wood finish) and high-quality build, reflecting Air Arms’ reputation for craftsmanship.  
• Comes with scope included — meaning fewer additional purchases needed to get sight-ready.
• “Very good condition” suggests that the rifle has seen use but remains well maintained; minimal wear, clean mechanics, and ready for reliable performance.

Why this is a strong buy:

The S400 is positioned around the £650-£800 new range for the .177 models.  For a second-hand rifle including scope, £400 represents very good value if the condition and optics are sound. The addition of the scope adds extra value.

What to verify before buying:

• Confirm actual condition: check stock for cracks/knocks, metalwork for wear or rust, barrel condition.
• Request recent performance data: chrono readings (FPS/energy), shot count per fill, smoothness of action and trigger.
• Scope: verify make/model, mounting condition, clarity of optics, zero/hang-up status.
• Air cylinder/reservoir condition: number of fills, any signs of internal corrosion or maintenance history.
• Legal compliance: ensure that the rifle’s power output and fill pressure comply with local regulations (UK sub-12 ft·lb if no FAC).
