Easy-to-use, no-nonsense design and performance in the field. The PA-08 is made for round after round of high volume shooting. 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.
