Mossberg's SA-28 is an easy-handling semi-auto perfectly suited for wingshooting, competition, turkey, and recreational shooting. The gas system vents excess gases to aid in recoil reduction and helps eliminate stress on operating components. This All Purpose Field model has a walnut buttstock and forend with a 14.5" LOP, 26" vent rib barrel with a matte blued metal finish, and a metal bead front sight. It includes Mossberg International's Sport Set of 5 choke tubes.
