For sale is a used Mossberg model 500A "tactical" shotgun. This is a 12ga that can use 2 3/4 inch or 3 inch shells.

This is the 18.5" breaching barrel.

Has shell saddle on 6-point adjustable stock (AR-style).

Holds 5+1 shells.

Shotgun still works/fires great! One owner since purchased from Sportsman's Warehouse in Tucson. 

Sadly, I don't get to shoot much anymore which is why it's for sale. 

I also have a LOT of 12ga 00 buck shells available separately.

Asking $450 OBO
