Browning Auto-5, which choke tube?

[Campbery]

Hi guys, looking at getting a turkey choke for a 20 year old Browning Auto-5. Threaded for tubes, 3'' chamber. Would this be a "invector plus" thread? Thanks

Most references state "Invector Plus" choking became standard in 1994.
(Invector Plus barrels are "overbored" )

If older than that, more than likely a standard Browning "Invector" choke.

Both types are still available, and they are not intechangeable with each other.

Your barrel will be clearly marked "Invector" or "Invector Plus" if it is a Browning barrel.
