Mark V Fibermark Composite

The Weatherby Mark V Fibermark Composite is a bolt-action hunting rifle chambered in nine calibers. The Mark V line is Weatherby’s premium grade rifles.

Weatherby is notable for their bolt-action operating systems–a modified Model 54 action–which is an early 20th century design for centerfire cartridges. Weatherby’s Mark V’s bolt body is designed with six lugs (nine for magnums) that secures the bolt firmly into the receiver. With more lugs, or wider lugs, the bolt requires a short 54-degree lift for full rotation and chambering. Weatherby also strengthened the bolt body by milling it from a single piece of steel, so it can withstand more powerful cartridges.

The Mark V Composite features a composite pillar bedded stock and fore-end. Pillar bedded stocks use aluminum or metal sleeves against which the action screws can be tightened–similar to fastening a screw into a plastic wall anchor rather than directly into a wooden board–it provides an overall tighter fit. In addition, the Mark V Composite has a steel barrel and receiver with a bead-blasted matte blue finish. Mark V Composite features a fully adjustable trigger that is initially factory-tuned to 3.5 pounds. Its bolt is flute, which reduces surface area in turn weight. At the end of the barrel is a target crown that helps reduce vibrations, which would otherwise throw off trajectory. The Mark V Deluxe is also equipped with a cocking indicator that visually indicates whether the rifle is uncocked or cocked, and it has a Pachmayr Decelerator brand recoil pad.

Weatherby recommends the Mark V Composite for hunting large game.
