Query: Doesent really fit an AK47 , 7.62x39 cal.

it doesent fit, or at least not thick enough to really clean the AK47 bore, even when fully soaking it in cleaner and fully dry it goes through but not tight enough feel to really clean or pull all the crap from the barrell, at least doesent feel that way, comes out very very easily.
