Douglas, it includes one invector style cylinder choke tube Wich works great for home defense loads and slugs. As others have mentioned modified and full are good to have. If you post again with your intended use can give you better options ard find the correct chokes for you if interested. Any invector plus 20 gauge choke will fit. Hope this helps.

Douglas, that depends on what you are going to use the gun for. If home defense is your only use, then no, do not spend your hard earned money on chokes you won't need. If you want a wider spread for maximum effect, go with cylinder. If you want a more tightly grouped shot for greater accuracy, go with Modified. IC is a good middle ground for those who want a bit of both. Different chokes explained here >>> https://winchester.com/Blog/2017/05/how-to-select-the-proper-choke-tube

no you do not NEED any extra chokes you gun comes with the Invector Plus Choke System with 1 Cylinder Choke Tube which is great for home defense or slugs. However you may want some tighter chokes (mod or full) if you are using the gun for other purposes

As mentioned below, you will a need a modified & full choke as well.

Hi Douglas, yes. It only comes with (1) Invector Plus Choke System with 1 Cylinder Choke Tube. You would need a Invector Plus Modified and Full Choke. Cheers and stay safe!
