'a near shot?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?

'shut completely' is the wordplay.

'completely' becomes 'up' (I've seen this in other clues).
'close'+'up'='CLOSEUP'

'through' acts as a link.
