FX Alu Air Cylinder, 500 cc

The FX Alu 500 cc air cylinder is an aluminium air bottle that increases the air capacity of FX air rifles. It suits the shooter who wants an extra or larger air bottle for a long day on the range or in the field and prefers a robust aluminium cylinder to carbon fibre.

The cylinder is 315 mm long and weighs 1000 g. That is more than an equivalent carbon bottle, but the extra weight can also be used actively to move the rifle's balance forward and make it steadier in the aim. The supplier does not state which FX models or what working pressure the cylinder is intended for – feel free to contact us before buying so we can confirm that it fits your rifle.

Aluminium instead of carbon fibre

The choice between aluminium and carbon is about weight, robustness and price.

• 500 cc volume: Gives more shots per fill than the smaller cylinders in FX's range and longer between fills.
• Aluminium construction: Aluminium is a robust, well-proven material for pressure cylinders and is less vulnerable to surface damage than the outer layer of carbon fibre.
• 1000 g weight: Heavier than a carbon bottle – a drawback when carrying, but an advantage for a steady, front-weighted rifle on the bench.
• 315 mm length: The length is on a par with FX's larger carbon bottles, so the rifle's overall length does not change significantly.
• Spare bottle: Can be used as an extra full cylinder, so you can swap instead of stopping to fill.

Maintenance and safety

• Only fill with clean, dry compressed air and never above the pressure stated on the cylinder and in your air rifle's manual.
• Check O-rings and threads before fitting, and follow the air rifle's manual for removing and fitting the cylinder.
• Avoid knocks, drops and direct heat. A cylinder with visible damage should not be filled until it has been inspected.
• Store the cylinder dry and at room temperature, and store the air rifle unloaded and out of reach of children.
