Moose feature (7)
I believe the answer is:
antlers
'moose feature' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for antlers that I've seen before include "Stag's crowning glory" , "Bony outgrowths on head of male deer" , "Head branches of 18" , "Branched horns" , "Reindeer outgrowth" .)
