Steambow: Crossbow, accessories and spare parts

Steambow has revolutionized the world of crossbows by developing a new generation of bolt weapon. Indeed, the manufacturer is behind the famous Steambow, a combination of a classic crossbow and its patented compressed air system PowerUnit as a cocking mechanism. 

Much more maneuverable, ultra-light, and practical to use, the Steambow adapts to any shooting conditions. Like a paintball gun, the crossbow has a pneumatic cocking device allowing for easy, quick, and silent cocking of the crossbow. Even the powerful Excalibur crossbows become very easy to cock as you only need to press a button to relax the bows and press again for the crossbow to be at full power.

With the PowerUnit, Steambow aims to offer professional users the best crossbows in the world. This invention results from cooperation between crossbow archers and a company specializing in the manufacture of precision parts for the aerospace, automotive, and arms industries.

Why choose a Steambow crossbow?

- Lightweight : as the crossbow is much lighter, the shooter doesn't need to exert a lot of physical effort to handle the weapon.

- Self-cocking : it becomes very easy to aim, cock, and shoot with the Steambow crossbow, the shooter can have a much faster rate of fire.

- Silent and versatile : this bolt weapon adapts to all types of crossbow shooting. Its applications are multiple.

- Foldable : the shooter also has a weapon that is easy to store and transport, whether for fun in the garden or to go to shooting ranges. 

- Robust : Steambow is a mark of quality, its products are known for their reliability, great robustness, and long lifespan.

How does it work?

The Steambow works like a traditional crossbow, with the difference that it is powered by compressed air and CO2 vapor tanks, exactly like in paintball. A simple button is used to tension the bows and cock the arrows. However, a compressor or a high-pressure manual pump is needed to recharge the tanks. This results in crossbows that combine comfort, power, precision, and practicality.

Technically, a crossbow becomes a complete Steambow once it has integrated a PowerUnit core. However, this system is only compatible with a handful of crossbows, including the Excalibur crossbows Bulldog 400 and Micro 350. It is necessary to adjust and configure the PowerUnit in the factory to adapt it to the crossbow model to be equipped. 

Discover the Steambow range

Steambow designs its parts and crossbows using robust materials such as 7075 aluminum (aviation alloy) and stainless steel with a high-quality surface coating. This ensures their durability and longevity. What models are available?

- AR-6 Stinger

The AR-6 Stinger crossbow pistol is an ultra-compact weapon suitable for sport shooting and leisure shooting. You can quickly reload bolts thanks to its rapid-fire magazine and quick-release lever. It is compatible with hunting arrows. In addition to a mechanical sight and an integrated laser sight, it can be accessorized with a red dot laser sight, tactical flashlight, and other adjustment parts. 

- AR-6 Stinger II, the redefined tactical crossbow

Weighing only 1.2 kg when equipped, this model is the lightest tactical crossbow on the market. It's also easily maneuverable and extremely fast thanks to the Speedloader and its AR-15 stock with integrated front sight. It can be safely transported even when loaded with bolts, although it's ready to shoot in an instant. This crossbow is for you if you're looking for an ultra-practical and intuitive weapon to use and aim for an accelerated rate of fire.

- Steambow Onyx

Onyx was the first true Steambow offered by the manufacturer. It's the perfect combination of a conventional crossbow with a compressed air gun. This tactical crossbow can function without compressed air or CO2 cartridges. Manual pressure applied to the button using optional accessories is enough to initiate automatic tightening and cocking. Onyx is just as fast, secure, practical, and versatile as the Stinger Steambow.

- Fenris

The Steambow Fenris is not quite a crossbow, it's more of a compound bow that the brand has coupled with an arrow loader. It allows you to shoot five arrows in a row in a few seconds, without releasing the bow. You only have to aim correctly and pull the trigger to launch the arrows. It's ideal for making effortless, ultra-fast, and more precise repetitive shots. It offers a rapid firing sequence that shooters quickly describe as addictive. 

A wide range of accessories

Many accessories are also offered with Steambow crossbows for simplified and comfortable use:

• laser sights for long-distance shots
• lasers and lights for shooting in darkness
• arrows
• special tips
• string
• handles
• sight rail
• CO2 cartridges...

The main advantages of the Steambow

Today, we will look at what makes the Steambow a revolutionary bolt weapon. As explained earlier, it is not an air crossbow, but rather the first self-cocking crossbow on the market with its patented compressed air PowerUnit system.

Steambow PowerUnit

Do you want to buy a Steambow? It's important to know some practical and technical information beforehand.

Compatible equipment

The Steambow PowerUnit is an automatic compressed air cocking system, compatible notably with the Excalibur Micro 355, Bulldog 400, and Bulldog 440. An identical system also equips the Steambow Onyx (the first Steambow), equipment specially developed for the PowerUnit.

Availability of compressed air bottles

The compressed air used by this cocking system is stored in small lightweight pressure bottles. These accessories can be easily obtained from specialized shops or stores in airsoft.

Reliability of the Steambow

In addition to being robust, the Steambow is also easy to use. To ensure your safety during use, it has a main valve capable of precisely and effectively regulating the cocking process. As for other safety systems, such as manual safety or trigger, they have not changed.

Cocking the Steambow

To cock your crossbow with the Steambow PowerUnit, simply:

• Put the limbs in the folded position;
• Hook the string in place and position the arrow (or a bolt if you prefer);
• Press the button, which activates a pair of pneumatic cylinders until the limbs are under tension.

When the Steambow is cocked, your crossbow is in the same condition as a classic model. Namely, all the technical specifications related to performance, such as arrow velocity, accuracy, power, etc., are identical on a Steambow.

Note: You can also manually cock your Steambow in case of lack of air.

Storage and Transport of the Steambow

To disassemble the Steambow, just remove the piston. The limbs will relax and you can store your bolt. It's worth noting that the least appreciated part of crossbow shooting is undoubtedly transportation. Fortunately, with the innovations brought to the Steambow, the limbs of your crossbow fold to make this task - in your vehicle or hiking in the woods - as painless as possible.

Ideal air pressure for a Steambow.

Consult the manufacturer's manual. Normally, it indicates that you can use one of the following alternatives:

• HPA Paintball systems (compressed air bottles) in aluminum or carbon fiber with an output pressure of about 59 to 66 Bar. Alternatively, use original Steambow compressed air bottles using only compressed air or nitrogen.
• Disposable 88-gram CO2 cartridges (requires adapters sold separately)
• Refillable CO2 tanks of any fill weight.

Number of cycles from a compressed air tank

This apparently varies depending on the size of the tank. But for more information, it's always best to refer to the manufacturer's user manual.
