Moment about right for stunt (5)
I believe the answer is:
trick
'stunt' is the definition.
(I've seen this before)
'moment about right' is the wordplay.
'moment' becomes 'tick' (I've seen this before).
'about' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'tick' placed around 'r' is 'TRICK'.
'for' acts as a link.
(Other definitions for trick that I've seen before include "Point gained in bridge - a deception?" , "Deceive, perhaps with cards" , "Illusion; artifice" , "Characteristic habit" , "Con" .)
