Mark V TRR Custom Magnum

The Weatherby Mark V Threat Response Rifle Custom Magnum is a bolt-action rifle chambered in .300 Win. Mag.,  .30-378 Weatherby Mag., .338-378 Weatherby Mag., and .300 Weatherby Mag. The Mark V TRR Custom Magnum is the premier model of Weatherby’s “threat response” 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 Weatherby Mark V TRR Custom Magnum is a tactically styled gun that features a fully adjustable composite stock with adjustable comb and a 26″ barrel with a matte black finish. It is equipped with a fully adjustable trigger that is initially factory-tuned to 3 pounds. Its bolt has a fluted body, which reduces surface area in turn weight. The Mark V TRR Custom Magnum also has a cocking indicator that visually indicates whether the rifle is uncocked or cocked and an Accubrake brand recoil-reducer.

Weatherby recommends the Mark V TRR Custom Magnum for home defense.
