The Bulldog .357 is a PCP bullpup chambered in .357, built around a rifled 28-inch steel barrel inside a shroud with a triangular-profile front and recessed muzzle. The factory design uses a sidelever repeating action and a 5-shot rotary magazine system, with an overall length of about 36 inches and a weight of about 7.7 lb. Note: on this example, the sidelever handle/assembly is missing.
Its air system is designed for a maximum fill pressure of 3000 psi (207 bar) feeding an approximately 340 cc reservoir. An analog manometer on the left side provides pressure status, and a male Foster-style quick-disconnect fitting ahead of the trigger guard serves as the fill interface.
A full-length top Picatinny rail runs the receiver, and this rifle comes with installed flip-up iron sights. The ambidextrous synthetic bullpup stock carries molded "BENJAMIN" branding and "B" medallions, finished in black.
The sidelever can be converted for left-hand operation per the factory manual; however, on this example the sidelever handle/assembly is missing. Factory markings include "BULLDOG .357" and "MODEL: BPBD3S .357 CAL." This example features custom, hand-applied white "HERCULES" lettering on the left buttstock. Selling as is.
