BULL’S NL Union & Union Pro Flight/Shaft Systems

Discover the BULL’S NL Union and Union Pro Flight/Shaft Systems – integrated solutions where the flight and shaft are permanently connected in one piece. The flight wings remain perfectly aligned at a 90° angle, providing consistent flight performance, quick installation and a reliable dart setup.

BULL’S NL Union & Union Pro Flight/Shaft Systems

The BULL’S NL Union flight/shaft systems combine the flight and shaft in one permanently moulded unit. This eliminates the need to assemble both components separately, while the flight wings remain evenly positioned at a permanent 90° angle.

You can choose between the proven BULL’S Union System and the further developed BULL’S Union Pro System. Both versions offer easy installation and a consistent setup, but differ in material, flight shape, stability and flight characteristics.

BULL’S Union Flight/Shaft System

The classic BULL’S Union System is made from a high-quality polypropylene blend. This integrated system is robust, durable and suitable for both beginners and experienced darts players.

The flight shape is approximately 2 mm narrower than a traditional No.2 standard flight. This creates slightly more space around the flights, which can be beneficial when darts are grouped closely together.

The Union System is noticeably heavier than a conventional combination of a nylon shaft and a No.2 flight. This shifts the overall balance of the dart slightly towards the rear. Players who prefer a calm and more rear-weighted setup may benefit from this weight distribution.

BULL’S Union Pro Flight/Shaft System

The BULL’S Union Pro System is the further developed and more stable version of the Union range. It was designed for players who place particular importance on durability, precision and controlled flight performance.

Its flight shape is based on a compact No.6-style flight. The aerodynamic profile is designed to provide a stable and straight flight. An integrated guiding groove can help following darts glide past darts already in the board and support tighter groupings.

The Union Pro has a firm but slightly flexible construction. This keeps the flight shape stable while allowing the material to give slightly during impacts and close groupings.

Which BULL’S Union System Is Right for You?

The classic BULL’S Union is particularly suitable for players looking for a robust flight/shaft system with a slightly narrower flight shape and a noticeable shift in balance towards the rear of the dart.

The BULL’S Union Pro is the right choice if you prefer a more compact flight shape, increased material stability and the additional guiding groove.

Selection advice

Flight shape, shaft length and weight all influence the balance and flight characteristics of your dart. If you have previously played with a traditional flight and shaft combination, the Union system may initially feel slightly different. Try different versions to find the setup that best suits your throwing style.
