Bergara B-14 Wilderness Series Sierra, Bolt Action Rifle, 300 Winchester Magnum, 22″ Fluted Barrel, Left Hand 300WIN

Product Description

The Bergara B-14 Wilderness Sierra in 300 Win Mag is built for the left-handed hunter who refuses to compromise on precision or field capability. This left-hand rifle features a mirrored bolt and stock, giving you the natural ergonomics right-handers take for granted—without sacrificing accuracy or adjustability. The Sierra Wilderness combines traditional hunting rifle ergonomics with modern precision features: an adjustable comb for perfect cheek-to-scope contact, fluted barrel for reduced weight in the mountains, and M5 bottom metal for seamless conversion between AICS detachable magazines and a hinged floor plate. Whether you’re stalking elk in Colorado or whitetail in Texas, this rifle adapts to how you hunt.

Specifications

What Makes the B-14 Wilderness Sierra Different

• Adjustable comb without buying a new stock. The side-mounted, Allen-key adjustable comb lets you dial in perfect eye alignment for any scope height or magnification. No gunsmith, no second stock—just turn a key and shoot.
• Fluted barrel for mountain weight and heat control. The No. 5 fluted barrel sheds pounds compared to standard Ridge profiles while improving heat dissipation during longer shooting sessions—critical in backcountry scenarios where every ounce matters.
• Hybrid magazine system built in. M5 bottom metal accepts modern AICS detachable magazines for fast reloads in the field, or flip to traditional hinged floor plate for classic field rifle simplicity. No tools required to switch.
• 300 Win Mag power in a hunting-weight package. The 300 Winchester Magnum delivers the velocity and energy needed for long-range game in a rifle that won’t beat you up on the hike in—7.4–7.7 lbs is realistic for a magnum hunting rifle.
• Left-hand ergonomics, no shortcuts. This isn’t a right-hand rifle converted for lefties. The bolt, safety, magazine release, and stock are all mirrored—you get the same speed and natural point of aim as any right-handed shooter would expect.

Bergara’s Barrel Story

Bergara has been making barrels in the Basque region of Spain for generations, earning a global reputation among precision firearms companies for consistency that rivals custom hand-lapped work. Every Bergara barrel goes through a five-step process: cold-straightening, deep-hole drilling, three-spindle diamond honing to a mirror finish, button rifling with carbide buttons held to less than .0002″ groove-diameter deviation, and high-temperature stress relieving. That process directly translates to the accuracy you’ll see out of this rifle—Bergara backs every B-14 with a sub-MOA guarantee, meaning your rifle will print under 1 inch at 100 yards with quality factory ammunition, straight from the box. When you’re glassing a mountainside at dawn, that consistency is what lets you make the shot count.

Action and Magazine Compatibility

The B-14 action is built on a Remington 700 footprint, which gives you access to decades of proven aftermarket stocks, chassis systems, triggers, and scope mounts. The two-lug system, coned bolt nose, and threaded oversized bolt knob are Bergara refinements over the original 700 design—they mean smoother feeding, a stronger bolt stop, and easier field adjustments. The M5 bottom metal accepts modern AICS magazines (standard in precision shooting) while retaining the option to use a hinged floor plate for traditional field hunting. This rifle doesn’t force you to choose between old-school reliability and modern convenience—you get both.

Trigger and Performance

The Bergara Performance Trigger is user-adjustable from 2 to 4 lbs with nothing more than an Allen key. The factory sets it around 3 to 3.5 lbs—a break that feels crisp and predictable without being hair-trigger unsafe in a hunting scenario. Reviewers consistently compare it favorably to upgraded aftermarket triggers costing twice as much. A good trigger teaches you to shoot better; this one won’t hold you back.

Why Choose This Left-Hand Configuration

Left-handed shooters often face a choice: buy a right-hand rifle and learn to work around it, or pay premium prices for a true lefty build. The Sierra Wilderness Left-Hand comes fully mirrored—bolt handle, safety, magazine release, comb adjustment, and stock geometry are all designed for your natural shooting position. You’re not making compromises; you’re getting a purpose-built rifle that handles as naturally as it should.

Frequently Asked Questions

Is this rifle truly left-handed, or just converted?

This is a true left-hand build. The bolt is mirrored with the handle on the left side, the safety is positioned for your left thumb, the magazine release works naturally for left-handed operation, and the stock comb adjustment is built into the left side of the stock. You’re not forcing a right-handed rifle to work for you—this rifle was designed for your shooting style from the ground up.

What makes 300 Win Mag the right choice for this rifle?

The 300 Winchester Magnum is one of the most versatile hunting cartridges available. It delivers flat-shooting ballistics and hard-hitting energy for elk, moose, and long-range deer without the recoil penalty of magnum overkill. In a 7.4–7.7 lb package with a quality muzzle brake, the recoil is manageable for extended shooting sessions in the field. If you’re hunting in varying elevations or taking longer shots, the 300 Win Mag gives you margin for error that smaller cartridges don’t.

Can I switch between AICS magazines and a floor plate?

Yes. The M5 bottom metal accepts standard AICS magazines for quick magazine changes, but it also accepts a hinged floor plate for traditional hunting. Switching between them requires no tools—just remove the magazine box or floor plate and install the other. This lets you hunt with a single rifle configured either way depending on the hunt: fast magazine changes in a gunning situation, or classic field rifle simplicity when you’re glassing and stalking.

What is the Bergara Omni Muzzle Brake?

The Omni Muzzle Brake is Bergara’s proprietary brake, threaded 5/8×24 (a standard pattern). It reduces recoil significantly and is finished in Sniper Grey Cerakote to match the rest of the rifle. It comes installed and ready to shoot. If you prefer a suppressor-ready setup or a different brake, the 5/8×24 threads accept any standard brake or suppressor.

What’s the benefit of a fluted barrel?

The fluted barrel reduces overall weight compared to a solid No. 5 taper barrel without compromising rigidity or accuracy. The flutes also increase surface area, which helps dissipate heat during shooting. For a mountain hunter, this means less weight to carry and a cooler barrel during longer strings of fire. The tradeoff is minimal—Bergara’s sub-MOA accuracy guarantee applies to fluted barrels just as it does standard barrels.

How do I adjust the comb, and is it worth it?

The comb adjustment is on the left side of the stock and uses a simple Allen key—no gunsmith needed, and it takes seconds. Proper cheek-to-stock contact is critical for consistent scope alignment and accuracy. If your scope is mounted high (as many hunting scopes are) or if you switch optics, the adjustable comb ensures you always have perfect eye relief and sight picture without buying a new stock or adding risers and shims.

What ammunition should I use for the sub-MOA guarantee?

Bergara’s guarantee applies to quality factory ammunition—loads like Federal Premium, Hornady Precision Hunter, Nosler Trophy Grade, or Remington Premier. Match-grade or hand-loaded ammunition will likely print tighter. Start with quality factory ammo from a trusted brand, and this rifle will shoot better than 1 MOA at 100 yards. Once you find the load it prefers, you’ll know exactly what to expect in the field.

Is this rifle compatible with Remington 700 accessories?

Yes. The B-14 action is built on a Remington 700 footprint, so you can use any 700-pattern stock, chassis, trigger, scope mount, or bolt-handle upgrade. That compatibility opens up decades of proven aftermarket options if you ever want to customize further. However, the Sierra Wilderness comes ready to hunt out of the box—you don’t need to buy anything else.
