Beretta Gas port cleaning tool

ACCORDING TO BERETTA, THIS IS THE PROPER SIZE TO CLEAN THE PORTS IN THE BARREL ON 303,390,391, AND MOST 400 AND 300 GUNS.
WILL NOT ENLARGE THE HOLES BUT CLEANS THE CRAP OUT OF THE HOLES TO MAKE THE GUN CYCLE. YOU MAY ALSO NEED AN ACTION SPRING INSIDE THE STOCK AND A GOOD CLEANING, BUT THIS USUALLY DOES THE JOB. THE PORTS CLOG UP WITH CARBON AND THE GUN DOES NOT CYCLE PROPERLY..... 25 DOLLARS INCLUDES POSTAGE ........I have several of these. I do paypal, venmo and zelle or plain snail mail checks
