Matures as a sniper, possibly (6)

I believe the answer is:

ripens

'matures' is the definition.
(ripening is a kind of maturing)

'a sniper possibly' is the wordplay.
'possibly' indicates an anagram.
'sniper' is an anagram of 'RIPENS'.

'as' acts as a link.

(Another definition for ripens that I've seen is " Matures".)

I've seen this clue in the Evening Standard.
