Stevens 12 ga SXS 113A - Chokes?

[Varmit]

Picked one up in good shape. Can anyone tell me how this gun would be choked? There is nothing on it to indicate anything and I haven't had a chance to pattern it yet. It has 30 inch barrels.

Seems like the gun is decently built for a low cost SXS that is meant for work.

Most likely Mod. and Full. Best off to take it in and have it checked. They may have been reamed out.
