All Weatherby PA-08 pump shotguns feature a ventilated top rib and brass bead front sight to aid in target acquisition. The vent rib works to dissipate heat in the barrel, promotes a smoother "swing-thru" and gives the shooter an excellent sight line for acquiring fast-moving targets. Each PA-08 gun comes with three application-specific, screw-in choke tubes. The Upland Slug Gun Combo comes with a walnut stock with gloss finish, 28" field barrel is gloss black for a distinctive look and a 24" rifled barrel with cantilever scope mount base in matte black.
