Built during the Paso Robles era, this Mark V Accumark carries the Weatherby script with PASO ROBLES, CA (U.S.A.) stamping and MARK V marking on the receiver ring. It has the signature two-tone look: a matte black receiver paired with a bright stainless barrel.
The 26-inch stainless barrel is a heavy profile with longitudinal flutes, a recessed crown, and a radial multi-port muzzle brake. The receiver is drilled and tapped for scope bases, and the rifle is configured without sights.
The composite stock is a black/gray spider-web finish with a Monte Carlo comb and right-hand cheekpiece. It includes sling-swivel studs and a Pachmayr Decelerator recoil pad. Length of pull is 13.5 inches.
The Mark V action features a bolt-shroud safety with red indicator and a large spherical bolt knob. Feeding is via a hinged floorplate internal magazine with a stated capacity of three rounds.
