New item required for archery is restricted (6)
I believe the answer is:
narrow
'is restricted' is the definition.
(I've seen this before)
'new item required for archery' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'item required for archery' becomes 'arrow' (bow and arrow).
'n'+'arrow'='NARROW'
(Other definitions for narrow that I've seen before include "lacks vision" , "Strait, not wide" , "Straight or tight" , "Constricted in width" , "Short of breadth" .)
