I'm planning another BSA Super10 project. This next donor is another MKIII bull barrel. My first carbine was on this same model, but I kept the Luxfer aluminum bottle (50mm dia.) when I added the quick fill unit and I never paid much attention to bottle diameter. When I built my second carbine, it was on a MKII with the exposed barrel. That one I reworked the whole system and went to a Huma bottle regulator/quick fill and I made a plenum to delete the factory regulator. I bought a 220cc carbon fiber bottle and then made a custom shroud for it, but didn't pay attention to the bottle diameter (55mm dia.) since I made the shroud to fit.
As I would prefer to keep the factory shroud unit while going to a larger capacity C/F bottle, I can't use a contemporary bottle as is typically sold for an FX which is 60mm in diameter. Has anyone run across a manufacturer that has C/F bottles 50mm in diameter?
I have looked at my MKIII and anything larger than 50mm will not fit without a radical change to the shroud or remake it as an offset design. I realize most normal people probably haven't gone around measuring bottle diameters, but if anyone has run across a manufacturer that does a 50mm C/F bottle, please let me know.
I should probably clarify that the desire to go with a C/F bottle is primarily for weight savings, as the factory supplied bottles are built like a brick outhouse and weigh about the same. I have done a fairly broad search, but many listings for bottles often don't have dimensions, that's why I'm asking here.
