Anxieties about container for firearms (8)

I believe the answer is:

carbines

'firearms' is the definition.
(carbine is a kind of firearm)

'anxieties about container' is the wordplay.
'anxieties' becomes 'cares' (care is a kind of anxiety).
'about' is an insertion indicator.
'container' becomes 'bin' (bin is a type of container).
'cares' enclosing 'bin' is 'CARBINES'.

'for' is the link.

(Another definition for carbines that I've seen is " Rifles".)

I've seen this clue in The Irish Independent.
