Can anyone help me with info on a Mossberg 930. I won this gun last winter at a DU banquet.
Its all black, 28" Vented barrel, 3" receiver, Semi-Auto. I cant find after market chokes for it. Moss 500 chokes are wrong size and Moss 835, 935 are 3 1/2" receivers so I think that rules them out. The gun came with 3 factory chokes, but I'm looking for more options. Any help would be great.

The mossberg 930 takes the same tubes as the 500 and the 535. The fact that it is 3" or 3.5" doesn't have anything to do with the chokes as the 535 is a 3.5" gun. I double checked that the 930 took the same as the 500 on the mossberg webpage. Here is the link. You can buy them right from the page. Hope this helps.
