As returned by some travel firm in Springfield? (5)

I believe the answer is:

rifle

I'm a little stuck... Click here to teach me more about this clue!

'springfield?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'as returned by some travel firm' is the wordplay.
'RIFLE' is hidden back-to-front in amongst the letters.
However, I'm not sure how this is indicated.

'in' is the link.

Can you help me to learn more?

(Other definitions for rifle that I've seen before include "Gun - ransack" , "Author of report" , "Ransack; a weapon" , "Long-barrelled weapon, normal army equipment" , "Winchester" .)
