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 in 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 PA-08 includes a walnut stock with gloss finish, gloss black metalwork for a distinctive look, vented top rib, 26 in chrome-lined barrel, 20 gauge (3 in chamber) and three application-specific choke tubes (IC, M, F)
