A armory for mister Quick-fix!

Since mister Quick-fix will going to sell the standard gear, overall old fashion weapons mass produced some decades ago i had a good idea regarding the setting / scene around mister Quick-fix.

Would be cool see mister Quick-fix inside a armory with these weapons, ammunition and other standard gear stocked.

A realistic place to find such a armory would be in underground locations but one in a city would not look bad as well.
