Tubes that constrict the column of shotgun pellets as they exit the barrel
For the Stoeger side-by-side shotgun, your best bet would be to use any of the standard Winchester choke tubes. They should fit well for you shotgun.
The Brazilian CBC Model 586 shotgun typically uses Beretta/Benelli Mobil choke tubes, which are also known as the Maxis chokes. You can use choke tubes compatible with this system in your CBC Model 586 shotgun.

System of changable shotgun choke tubes made by Mossberg. Accu Choke is their brand name. A shotgun choke is a means of reducing the bore size at the muzzle of a shotgun, to produce shot patterns that spread to a greater or lesser degree.

If it has choke tubes, yes. If it is fixed choke, no. I called Browning about mine and that was the answer they gave me.
Rem-Choke
