The Dickinson Tac-4 ST is a pump-action 12 gauge built for home defense and range work (Dickinson part no. TAC4ST). An 18.5-inch barrel with a fixed choke keeps it maneuverable, while the 3-inch chamber takes both 2-3/4-inch and 3-inch shells. A synthetic stock with an adjustable comb and a Picatinny rail on the receiver set it up for optics, and ghost ring sights come on the gun. The magazine holds five rounds, so a full load is 5+1. This is a straightforward pump gun for owners who want a tactical layout.
