Will a "Kick 1" fit into a 21mm Caravela mod clone tube? (too small?)

[Flt Simulation]

I know the 'Kick 1" will fit in a Caravela 22mm (outside diameter) clone tube, but do you think it will fit a 21mm Caravela clone tube.

The reason I ask this is because there is a group buy on a Caravela clone (with a single 21mm outside diameter 18650 tube) for $15 at Focalecig.

I know were talking about outside diameter here, and what matters is the inside diameter where the Kick will fit, but unless the wall of the 21mm tube is very very thin, I would think that the inside diameter of the 21mm tube would be smaller than the inside diameter of a standard 22mm mod tube.

Any idea?

fits in a origin 21mm mod no problem.

it's the diameter of the battery so it should be fine.

you won't be able to go 18650 mode with a kick unless you are using an 18490 battery with it
