Ruing a broken weapon (6)

I believe the answer is:

airgun

'weapon' is the definition.
(airgun is a kind of weapon)

'ruing a broken' is the wordplay.
'broken' indicates an anagram.
'ruing'+'a'='ruinga'
'ruinga' is an anagram of 'AIRGUN'.

(Another definition for airgun that I've seen is " Weapon with small shot".)

I've seen this clue in The Irish Independent.
