To change the choke of the shot
Yes
Browning's web site has the current information.
Yes, in the new A5.
The Invector, or "Standard Invector" system" was introduced in 1983. A few years later, the Invector-Plus chokes were introduced to fit the new back-bored shotgun barrels. These two choke systems will not interchange. If you have screw-in chokes in your shotgun barrel, the kind of system you have will be stamped on the barrel near the receiver. You must use the proper choke system for your shotgun.
Should be interchangeable with Winchester chokes. http://www.choketube.com/guide.HTML Used browning invector chokes in my condor 1 o/u
Introduced in 1973, the Citori was the first Japanese made Browning. Fixed chokes were the only option until the Invector choke became available in 1983. The fixed chokes and Invectors were both available on the Citori for a few years until in 1989 when the Invector became standard on all guages except the 28ga and .410.
It came with the Invector system which allowed changing chokes.

No. Not recommended. The barrel walls are not fit for screw in chokes. Belgian A-5 barrels that had that procedure done in the 60's and 70's were mostly unsuccesful. The barrels ended up being cut down or discarded. Aftermarket screw in chokes worked well with the Over/Under Browning guns, but not the Automatics. It's recommended to purchase a Japanese made barrel (with invector chokes) and have it fitted to your Belgian gun.
