Mid-length gas tubes?

[Triton225]

May be a dumb question, but. Is there any differences between joe vs. bobs gas tube lengths(all being mid-lengths)? If so, is it enough to matter?
When I ordered my DD barrel and rail, they didn't have any tubes to sell. So I still need to pick up a tube.

There shouldn't be any differences in them.

They probably all come from the same place anyway, not too many gas tube factories around.

That being said, I bought a blackened LMT mid-length gas tube from Operation Parts. Does exactly what its suppose to do; be a gas tube and be black.

Some may or may not come with the gas tube roll pin, so be aware of that.
