Upper limbs (4)
I believe the answer is:
arms
'upper limbs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for arms that I've seen before include "you'll find in the gunroom" , "Blazonry; weaponry" , "Members" , ". . . . and the Man (G B Shaw) (4)" , "Weapons and limbs" .)
