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 PowerUnit system 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 to arm the crossbow easily, quickly and silently. Even the powerful Excalibur crossbows become very easy to cock as you just 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 the cooperation between crossbow archers and a company specialized in manufacturing precision parts for the aerospace, automotive and armament industries.

Why choose a Steambow crossbow?

- Light: 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 backyard or going to shooting ranges.

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

How does it work?

The Streambow 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 draw the bows and arm the arrows. However, you need to use a compressor or a high-pressure manual pump to refill the tanks. This results in crossbows that combine comfort, power, precision and practicality.

Technically, a crossbow transforms into 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 at the factory to adapt it to the crossbow model to be equipped.

Discover the Steambow range

Steambow designs its parts and crossbows from robust materials such as 7075 aluminum (aviation alloy) and stainless steel with a high-quality surface coating. This guarantees 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 recreational shooting. Arrows can be quickly reloaded 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 light 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 is 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 armed with arrows although it's ready to shoot in no time. This crossbow is made 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 pistol. This tactical crossbow can operate without compressed air or CO2 capsules. Manual pressure on 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 Streambow 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 just have to aim correctly and pull the trigger to launch the arrows. It's ideal for making repetitive shots without effort, ultra-fast, but more precise. 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 capsules...

The main advantages of the steambow

Today, we're going to look at what makes the Steambow a revolutionary bolt weapon. As explained previously, it's 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 shops or stores specializing in airsoft.

Reliability of the steambow

In addition to being robust, the Steambow is also easy to use. To ensure your safety during its use, it has a main valve capable of precisely and effectively regulating the cocking process. For other safety systems, we can notably mention the manual safety or the trigger, which have not changed.

Cocking the Steambow

To arm your crossbow with the steambow PowerUnit, you just need to:

• Put the limbs in 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 armed, your crossbow is in the same configuration as a classic model. This means that 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 arrow. 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:

• Paintball HPA systems (compressed air bottles) in aluminum or carbon fiber with an output pressure of about 59 to 66 Bar. Otherwise, use original Steambow compressed air bottles using only compressed air or nitrogen.
• Disposable 88-gram CO2 capsules (requires adapters sold separately)
• Refillable CO2 tanks of any filling 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 better to refer to the manufacturer's user manual.
