I think it looks pretty good, ought to do the job.
However since you asked for feedback:
As for detailing; i would suggest either a grid pattern to compliment the pattern on the tail just not at 45 degrees, or just some rings, but either choice should use a similar radius and spacing to the pattern in the tail.
As for the lip; i think keeping a smooth transition between the smooth head section and the extender would look best but would it be possible to give the other end a 10-20 degree chamfer down to the smaller diameter of the tail, i feel this would look a little neater and feel better in the hand.
Also i agree with gunga that it could do with an o-ring channel, the TC-R1 comes with a spare o-ring which is lucky.
All that being said i'll go for one of each type whether any of these features are implemented or not but i also won't be upset if your initial quoted price goes up if you do implement any.
