Relative into gun-cleaning (5)

I believe the answer is:

uncle

'relative' is the definition.
(uncle is a kind of relative)

'into gun-cleaning' is the wordplay.
'into' indicates a hidden word.
'UNCLE' is hidden in the letters of 'gun cleaning'.

(Other definitions for uncle that I've seen before include "Grandfather's son" , "Male relative - pawnbroker" , "One receiving pawn" , ". . . . . Sam, the US government" , "Slang name for pawnbroker" .)
