PGP. Built by Benjamin/Sheridan and based on their BB/pellet guns, the PGP was one of the early guns of paintball, and spawned an entire line of guns distributed by Pursuit Marketing Inc.  Palmer Pursuit Shop guns, the WGP Autococker, and today's two-tube blow-backs, all owe their ancestry to the PGP. The gun has a 10 round magazine in the top tube, the barrel is the middle tube, and the lower tube holds the 12 gram Co2 catridge and the valve system. This gun also has a Tasco 25mm red dot sight. The inset shows the gun with a barrel extension and silencer.
