The Best Fittings 1.1 Litre 300 BAR “Weekender” Carbon Fibre Airgun Charging Cylinder is a compact and lightweight charging solution designed specifically for airgun shooters who want convenient refilling in the field or at home. Built using a carbon fibre wrapped composite cylinder, this high-pressure system offers outstanding strength while keeping overall weight exceptionally low, making it ideal for transport in a vehicle, kit bag, or range setup.
Unlike traditional systems that rely on screw-in charging heads, the Weekender cylinder is fitted with a dedicated Bisley airgun charging valve, allowing you to fill your buddy bottle directly from the valve with ease. It can be filled directly from a standard DIN 300 diving compressor fitting, making refilling straightforward at dive centres or with appropriate charging equipment. A Bisley pressure gauge is fitted as standard for clear pressure monitoring, while a 300mm BEST Fittings Ultima hose provides reliable and convenient connection to your airgun.
Despite its compact size, this cylinder delivers impressive performance. The 1.1 litre capacity with a 300 BAR (4500 PSI) working pressure allows multiple refills from a single charge, typically providing six or more refills for an Air Arms S410, making it an ideal “weekend shooting” companion. Thanks to the carbon fibre construction, the system weighs just 1.8kg including the valve and hose assembly, giving shooters a powerful yet highly portable charging solution.
Manufactured exclusively for BEST Fittings, these cylinders are brand new and fully CE marked, meeting EN12245 European certification standards and approved for use across the UK and European Union. The cylinder features a 15-year design life with a five-year hydrostatic test cycle, ensuring long-term reliability and safety when maintained correctly.
With dimensions of 85mm diameter and 425mm height including the valve, and a standard M18 x 1.5 neck thread, the Weekender cylinder combines high performance with practical portability. To comply with shipping regulations, cylinders are supplied empty.
