Weapon search (5)
I believe the answer is:
rifle
I believe this clue is a double definition.
'weapon' is the first definition.
(rifle is a kind of weapon)
'search' is the second definition.
(I know that rifle is a type of search)
(Other definitions for rifle that I've seen before include "An arm" , "Pillage; a weapon" , "Gun - steal" , "Gun - ransack" , "Ransack - firearm" .)
