The Weatherby Mark V Apex is a bolt-action rifle chambered in .257 Weatherby Magnum, built around the Mark V action with a 26-inch #3 contour barrel. It weighs 7.5 lbs. and runs 48 inches overall — light enough for long carries and long enough for full powder burn in that cartridge.

Features 

The barrel has a two-tone Coyote Tan / Graphite Black Cerakote finish and is fluted, which trims weight and pulls heat away faster during sustained strings of fire. 
 
The stock is carbon fiber with a tan/brown sponge pattern and exposed carbon accents. It is noticeably lighter than a comparable fiberglass or wood stock, which matters when you're hauling a rifle over rough country all day. 
 
The Trigger Tech Field system is adjustable from 2.5 to 5 lbs. pull weight. That range covers most preferences without requiring a gunsmith visit. 
 
The integrated Accubrake ST muzzle brake cuts felt recoil enough that follow-up shots are faster and the rifle stays more planted between rounds — a real advantage with a cartridge that moves as quickly as the .257 Weatherby Magnum.

The Mark V Apex in .257 WBY draws consistent praise for its bolt smoothness and the quality of the Cerakote work. Hunters who carry it long distances appreciate the weight savings from the carbon fiber stock; the 7.5 lb. figure holds up in the field. The .257 Weatherby Magnum's flat trajectory and velocity get frequent mentions from both hunters and long-range target shooters.

The price is the most common sticking point. Most owners feel the build quality justifies it, but shooters who don't need magnum performance or the specific weight reduction can find acceptable alternatives for less. A handful of owners with less trigger experience mention that the lighter pull settings feel different than what they're used to, though most adapt quickly.

Aftermarket support for the Mark V footprint is narrower than for some more common platforms, which frustrates buyers who want to heavily customize their rifle. That said, the platform comes well-sorted from the factory, so many owners find they don't need to change much.
