Rifle raised for drill, perhaps (4)
I believe the answer is:
tool
'for drill perhaps' is the definition.
(drill is a kind of tool)
'rifle raised' is the wordplay.
'rifle' becomes 'loot' (I've seen this before).
'raised' is a reversal indicator (going up in a down clue).
'loot' reversed gives 'TOOL'.
(Other definitions for tool that I've seen before include "Person used by another" , "For example, saw" , "Hand implement" , "Practical implement" , "Device, implement" .)
