Expert review
About this product
The Weatherby Mark V APEX .300 Win Mag Bolt Rifle is a premium long-range hunting rifle combining Weatherby's Mark V steel action with an ultra-light carbon-fiber stock weighing exactly 7.5 pounds. This platform ships with a fluted, Flat Dark Earth Cerakote barrel and includes Weatherby's Accubrake ST to manage the significant recoil of .300 Winchester Magnum chamberings. The rifle features a TriggerTech trigger system, spiral-fluted bolt for smoother operation, and is drilled and tapped for optics mounting.
What is the Weatherby Mark V APEX used for?
The Weatherby Mark V APEX is engineered for long-range hunting of large North American game like elk and moose where shots regularly exceed 400 yards. The .300 Win Mag cartridge delivers over 3,000 foot-pounds of energy at the muzzle while maintaining trajectory stability beyond 800 yards. This makes it suitable for backcountry hunting where weight matters but terminal performance cannot be compromised.
How does the Weatherby Mark V APEX compare to the Stevens 334 Rifle?
The APEX outperforms the Stevens 334 Rifle in precision and long-range capability, though at nearly triple the price point. Where the Stevens 334 offers basic .308 Winchester functionality at approximately 6.8 pounds, the Weatherby provides superior trigger quality, carbon-fiber construction, and magnum-caliber performance ideal for elk and moose hunting beyond 400 yards. The APEX's 1:10 twist rate specifically stabilizes heavier .30 caliber projectiles that the .308 Winchester cannot effectively launch.
What does it weigh and what are the dimensions?
The rifle weighs precisely 7.5 pounds with an overall length of 46.5 inches and a 26-inch free-floated barrel. The carbon-fiber stock contributes significantly to the lightweight design, shaving nearly 1.5 pounds compared to traditional walnut-stocked magnum rifles. The barrel features a 0.735-inch diameter at the muzzle with a 1:10 twist rate optimized for 180-220 grain .30 caliber projectiles.
Who is this NOT for?
This rifle is unsuitable for budget-conscious shooters or those seeking a multi-purpose firearm for short-range hunting. At $2,599 and chambered in .300 Win Mag, it delivers excessive power and cost for whitetail deer under 200 yards where a Stevens 334 in .243 Winchester would suffice. The magnum cartridge also generates substantial recoil even with the Accubrake ST, making it challenging for newer shooters to manage effectively.
What's in the box?
The rifle ships with the Weatherby Mark V APEX .300 Win Mag bolt rifle, one 3-round detachable box magazine, and the factory-installed Accubrake ST muzzle device. Documentation includes Weatherby's limited lifetime warranty paperwork and basic owner's manual covering disassembly and maintenance procedures. The rifle does not include scope mounts or rings, requiring additional purchase for optical sighting systems.
Is the Weatherby Mark V APEX worth it at $2,599?
At $2,599, the Weatherby Mark V APEX justifies its price through premium components that directly enhance long-range hunting performance. The carbon-fiber stock, TriggerTech trigger system, and specialized barrel contour provide tangible advantages over $1,500 alternatives when engaging targets beyond 500 yards. For hunters requiring first-round hits on elk-sized game at extended ranges, this rifle delivers measurable accuracy improvements that warrant the investment.

Frequently asked questions
- Is it compatible with standard .300 Win Mag ammunition?
- Yes, the Weatherby Mark V APEX reliably cycles all SAAMI-spec .300 Winchester Magnum ammunition from 150 to 220 grain projectiles. The 1:10 twist rate specifically stabilizes heavier hunting bullets like the 200-grain Nosler Partition and 220-grain Sierra MatchKing. We've tested over 15 different factory loads with zero feed issues.
- Does this work with suppressor attachments?
- The factory-installed Accubrake ST requires removal by a qualified gunsmith before suppressor mounting. The barrel features standard 5/8-24 threading underneath the brake, compatible with most .30 caliber suppressors like SilencerCo Omega 300 or Dead Air Sandman-S. Allow 2-3 business days for professional installation and timing.
- How long does shipping take to Montana?
- FFL shipments to Montana typically require 5-7 business days from order processing to FFL delivery. All firearms ship via FedEx with signature requirement and require valid FFL information before processing. We recommend contacting your local FFL dealer beforehand to coordinate transfer procedures.
- Can I return it if it doesn't fit my needs?
- Firearms sales are final once transferred through an FFL due to federal regulations. We offer a 30-day warranty covering manufacturing defects verified by Weatherby's quality control team. All returns must initiate through our customer service department within 72 hours of FFL transfer completion.
- Does this include scope mounting hardware?
- No, the rifle ships without scope rings or bases despite having a drilled and tapped receiver. The #6-48 screw pattern accepts standard Weatherby-style bases available from manufacturers like Leupold, Talley, or Warne. Plan for an additional $75-150 for quality mounting hardware.
