The Weatherby Mark V Apex .300 Winchester Magnum Rifle is a bolt-action rifle chambered in .300 Winchester Magnum, set up with a 26-inch barrel threaded 5/8-24 and a factory muzzle brake (brand part no. MAX01N300NR8B). It is built on Weatherby’s steel Mark V action and wears a fluted, two-tone Cerakote barrel with an exposed carbon fiber stock, a combination the maker pitches as long-range accuracy in a lightweight hunting rifle. A TriggerTech trigger, a 54-degree bolt throw and a 3DHEX recoil pad round it out. It holds 3+1 rounds and uses a 1-in-10 twist, which makes it a fit for long-range hunting where every ounce counts.
