Compact weapons sent from the east (4)
I believe the answer is:
snug
'compact' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for snug that I've seen before include "Cosy and comfortable" , "Comfortable -- small secluded room" , "Comfortabel with guns" , "Close-fitting and cosy" , "joiner" .)
