Walther CO₂ Air Rifles – German Precision & Power

Walther PCP and CO₂ air rifles for target and recreational shooting

Walther air rifles combine the German brand’s long-standing association with precision shooting with modern systems designed for target practice and recreational use. The current range is centred mainly on PCP air rifles and CO₂ air rifles, with conventional and bullpup configurations suited to different shooting preferences.

In this collection, you can compare the Walther air rifles available at Carbin by power system, calibre, stock design, magazine capacity, charging method and intended use. To explore all available brands and operating systems, visit our main air rifles collection.

Choosing the right Walther air rifle

The right Walther air rifle depends primarily on how you intend to use it. PCP models such as the Rotex RM8 and Reign are designed for shooters who value consistent performance, minimal mechanical movement and a stable platform for accurate shooting.

The Walther Lever Action CO₂ range delivers a different experience. Its underlever action, rotary magazine and traditional styling make it particularly appealing for informal target shooting and plinking at short to medium ranges.

Before choosing a model, check the specifications of the exact version carefully. Calibre, magazine capacity, fill pressure, charging connector, rail type, stock material and included accessories may vary between models and configurations.

Walther and Umarex in the airgun market

Walther is a historic German brand with a strong reputation in precision and sporting firearms. Within the recreational airgun sector, a number of Walther-branded models are developed or distributed within the Umarex group and its international airgun portfolio.

This relationship brings the Walther identity together with modern airgun technology, including pre-charged pneumatic systems, CO₂ power, multishot rotary magazines and practical scope-mounting options.

Walther Rotex RM8: a versatile PCP air rifle

The Walther Rotex RM8 is a multishot PCP air rifle built around a conventional sporting configuration. It is a strong option for shooters looking for a familiar handling position, good balance and consistent performance across a complete shooting session.

Depending on the version, the Rotex RM8 may feature a wooden stock or a synthetic Varmint-style stock. Available calibres and individual technical specifications can also vary, so the product page for the exact model should always be checked.

• Pre-charged pneumatic operation.
• Multishot rotary magazine.
• Conventional and well-balanced layout.
• Wooden and synthetic-stock versions.
• Suitable for regular target and precision shooting.

Walther Reign: a compact bullpup PCP air rifle

The Walther Reign uses a bullpup configuration, positioning the action and magazine farther back in the stock. This layout reduces the rifle’s overall length while retaining a barrel suitable for accurate shooting.

Its compact design makes the rifle easier to handle and brings much of the weight closer to the shooter. It is designed for users looking for a modern, manoeuvrable and multishot PCP air rifle.

• Compact bullpup configuration.
• Pre-charged pneumatic system.
• Multishot operation.
• Balanced and manageable shooting position.
• Contemporary performance-oriented design.

The Reign and Rotex RM8 both use PCP technology, but their handling characteristics are different. The Rotex RM8 follows a traditional rifle layout, while the Reign prioritises compact dimensions and bullpup ergonomics.

Walther Lever Action: classic CO₂ air rifles

Walther Lever Action air rifles recreate the distinctive operation and appearance of traditional lever-action rifles in a CO₂-powered airgun platform. They fire 4.5 mm pellets from a rotary magazine, allowing smooth and enjoyable follow-up shots.

Standard, Wells Fargo and Steel Finish versions share the same general lever-action concept while offering different finishes and visual styles. They are particularly well suited to recreational shooting, plinking and shooters who appreciate traditional Western-inspired designs.

Walther PCP vs CO₂ air rifles

Which calibre should you choose?

The calibre should be selected according to the type of shooting, expected range and the exact version available. The most common calibres within the Walther air rifle range are 4.5 mm (.177) and 5.5 mm (.22).

• 4.5 mm (.177): generally offers a flatter trajectory and is widely used for target shooting and plinking.
• 5.5 mm (.22): uses a heavier pellet and is available in selected Walther PCP configurations.

Walther Lever Action rifles generally use 4.5 mm pellets. The Rotex RM8 and certain other PCP versions may be available in either 4.5 mm or 5.5 mm. Always confirm the calibre and specifications shown on the individual product page.

Which Walther air rifle is right for you?

• For recreational shooting: a Walther Lever Action CO₂ rifle provides intuitive handling and an enjoyable shooting cycle.
• For a conventional PCP rifle: the Rotex RM8 offers traditional ergonomics and good versatility.
• For a compact PCP: the Walther Reign provides increased manoeuvrability through its bullpup layout.
• For a wooden stock: check the corresponding Rotex RM8 and Lever Action versions.
• For frequent shooting: consider the charging equipment, magazine capacity and expected shot count as well as the rifle itself.

How do you fill a Walther PCP air rifle?

A Walther PCP air rifle must be charged with clean, dry compressed air while observing the maximum fill pressure specified for the exact model. Depending on how frequently you shoot, the rifle can be filled using a high-pressure hand pump, a suitable air bottle or a PCP compressor.

Before filling the rifle, confirm that the fill probe or quick connector is compatible, inspect the condition of the high-pressure hose and check the remaining cylinder pressure. Never exceed the manufacturer’s stated maximum fill pressure.

For a more independent filling setup, explore our PCP compressors for air rifles.

Which CO₂ cartridges does a Walther Lever Action use?

Walther Lever Action models use a specific CO₂ power system. The required cartridge size must always match the information given on the product page and in the manufacturer’s instructions. An incompatible cartridge should never be forced into the rifle.

Temperature can affect CO₂ pressure and rifle performance. In cold conditions, shot count and consistency may be reduced. It is also advisable not to leave a partly used cartridge installed during long-term storage, as prolonged pressure can affect the seals.

Scopes, rails and accessories for Walther air rifles

The most suitable sighting system depends on the rifle and the intended shooting distance. Some Walther models use an 11 mm dovetail rail, while others may feature a Picatinny or Weaver-style interface. Always check the rail type and width before choosing scope mounts or rings.

For short-range recreational shooting, a red dot sight can provide quick target acquisition. For more precise target work, an airgun scope with an appropriate magnification range allows finer aiming and more accurate shot placement.

Other useful accessories include correctly sized pellets, targets, cleaning products, fill probes, spare seals and charging equipment compatible with the selected PCP or CO₂ system.
