Punch American — listen to riot outside (7)

I believe the answer is:

nailset

'punch' is the definition.
(I've seen this before)

'american listen to riot outside' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'to riot' indicates anagramming the letters.
'outside' is an insertion indicator.
'listen' is an anagram of 'nilset'.
'a' placed inside 'nilset' is 'NAILSET'.

(Another definition for nailset that I've seen is " punch".)

I've seen this clue in The Guardian.
