Yes,but,most will need a gunsmith and will void the manufacterers guarantee.The add on s that clamp to the end of the barrel are not effective and they are dangerous.Have a good gunsmith or shotgun specialist tap and install the chock.
On the choke tubes. It is marked by lines on the front edge of the choke. The more lines the more open the choke. 1 line is a full and goes from there. If it doesn't have tubes, on the inside of the receiver near the bbls.

To determine different shot patterns
With the advent of interchangeable choke tubes, there really is no such thing as "usual". Most will come with modified and improved.
They identify which chokes you have in without having to use a choke tool. different companies have different markings but in general the fewer marks, the more constricted the choke (1 mark=full choke).
Browning made choke tubes.
Invector was Brownings original choke tubes that came out in 1983. Invector Plus came along later for the back bored barrel shotguns. They are not interchangeable. Invector Plus= late model shotgun, Invector = earlier design shotgun. Both are still available for purchase.
Modified describes a choke. Invector is a system of choke tubes.
A choke, as it relates to firearms, is a narrowing of the end of the shotgun barrel. This narrowing can be greater or smaller. Chokes that are smaller than the bore to a greater degree are called tight chokes. Choke affects the shot pattern. Different chokes act differently with different loads and shot types. Choke tubes are steel tubes with threads on the outside and one end having the same diameter as the bore and the other end being narrower to various degrees. These tubes are screwed into the end of the shotgun barrel to vary the choke. This provides shooters with more flexibility in using their guns for different types of shooting and different loads.
I am a gun dealer in Asheboro, NC (Franks gun and pawn). Yes, the Baikal choke tubes will fit. This gun is made by Baikal for Remington. It used to be imported under the EAA name. You can also get tubes at Colonial choke tubes.
We are not familiar with a model 22, but all Browning Shotguns use the invector screw in choke tubes. These are available at most Gun Shops and retailers of Browning guns. You can also find them online at the Browning Co Website
