Just noticed this in an airgun magazine but seem to have lost it, so I don’t know anything other than it’s a twin air tube PCP made by Air Arms for the Italian company Domino?

Why not just a single, larger tube? Hence bottle guns...
Although I do like the look of tubes in lieu of bottles. |

weight....One large tube would need a thinker wall after all as the dia increasses so dose the surface area...
So two small dia tubes with thiner walls may in fact be lighter...

I did a quick comparison between 0.875" OD x 0.093 wall (3000 psi rating).... and 1.25" OD x 0.134" wall (2950 psi rating)....
40" of the smaller tubing has the same volume as 19.7" of the larger tube.... and 40" of the smaller tube weighs the same as 19.5" of the larger tube....
It's pretty much a wash comparing volume and weight.... and if the two sizes had exactly the same pressure rating.... my guess is the difference would be zero....
