Theoben bottle advice, wanted

[leons]

think because of the size and density that these buddy bottles are not under the same regs as standard compressed air cylinders...not 100% though

Thanks for that..

Does anyone have any more to add...Please

Only from a technical point of view. Due to the relatively small volume to surface area and thickness of the cylinder walls, stress to the material is reduced. This means the usual problems associated with pressurization and de-pressurization of BA cylinders or dive cylinders are greatly reduced the smaller the container (keeping in mind that the thickness of the walls increases proportionately the smaller the container gets). For this reason many people who have worked with life support cylinders (BA, SCBA etc...) are taught to release and fill very slowly as the rapid temperature and pressure changes can stress the aluminium or steel. I know that I still keep to my training and fill my buddy bottle slowly to reduce stress. If the bottle seems to be in good shape externally and there are no tell-tale signs of abuse to the cylinder you should not have any problems. I am still using 2 SCBA cylinders that were manufactured in 1980 but due to their careful maintenance/filling and regular inspections am totally confident that I am safe. My opinion (although not professional on buddy bottles) is that the bottle will outlast many of the parts on the actual rifle.
