BSA Replacement Air Cylinder Tube - 425mm

This is a longer replacement air cylinder for all BSA Ultra/Scorpion SE, Ultra MMC, Scorpion and Goldstar SE models to give a larger air capacity, therefore higher shot count. Please be aware fitting a longer air cylinder may also require an aftermarket shroud as you may no longer be able to use a moderator. This can also be used with the BSA Hornet models, however there is no internal machining for the original Hornet regulator, but it can be used with an external aftermarket regulator with no issue.

Once fitted the fill pressure is still 232 bar, if your air rifle has been fitted with an after market regulator then you may be able to fill to 250 bar but please check before you purchase this item. 

The air cylinders are blued steel finish to match the original factory finished parts.

These replacement air cylinder can also be supplied with a quick fill unit that has a gauge, not only is this lighter and more reliable than the factory fitted quick fill, it is also fully serviceable and comes with a spare set of orings as well as a new fill probe.
