Availing oneself of gun is wrong (5)

Ross

I believe the answer is:

using

'availing oneself of' is the definition.
(I've seen this in another clue)

'gun is wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'gun'+'is'='gunis'
'gunis' with letters rearranged gives 'USING'.

(Other definitions for using that I've seen before include "Exercising" , "having recourse to" , "addiction" , "practice" , "taking drugs" .)
