Hi David, yes, the picatinny mount is included with this model. It will mount on your shotgun if you have a picatinny rail. If you have a dovetail rail, you will need an adapter >>> amazon.com/gp/product/B01ABW7GS0/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
If you have neither, you will need a pic rail that lines up with your drilled/tapped receiver.
Stay safe & have a great day!
