You could shave some weight off if you used a bracket to secure a tube to the nose of the cylinder so that only the piston rod is enclosed. You might need to rethink mounting, but the weight saved would be non-negligible. In addition, it could be argued that such a design would be more faithful to the name.

Generally, in my experience, these kinds of things are more for saving space than weight. Square tube is also much easier to mount things to.
