The word ending <oric(al)> is usually pronounced ɒrɪk(l), not ɔːrɪk(l). Here are a few examples:
alleˈgorical cateˈgorical euˈphoric hiˈstoric(al) meteˈoric
There are some words which allow the ɔːrɪk(l) pronunciation, but you won’t go wrong if you stick to ɒrɪk.
Note the place of the main stress in these words.
An exception: the noun rhetoric is pronounced ˈretərɪk.
