Browning A-5 barrel change

Question
I recently purchased from an estate a 20 ga Browning Auto 5 full choke shotgun with an extra modified choke barrel.  I have been unable to find any information on how to switch from one barrel to another.  Are you aware of anyone who sells barrels suitable for steel shot for this firearm?
Thank You

Answer
Steve,

I am 99% sure you can use the Japanese made A-5 barrels to shoot steel shot thru the gun. I would look at gunsamerica.com, or gunbroker.com. There are always A-5 barrels on these sites. Switching the barrels is easy by holding the barrel firmly down into the rec'r slightly and unscrewing the forend cap. Pull the forend off and gently/slowly allow the barrel to come back up and off.
