Bergara Sierra Bolt Action: Adjustable Comb for Precision Shooting

When you’re on the hunt for a bolt-action rifle that blends traditional sporter lines with modern adjustability, you want a platform that can be tuned to your body and your mission. Comfortable, precise shooting starts with fit and geometry—especially the cheek weld and length of pull—and the right rifle gives you that flexibility without compromises.

BERGARA B-14 WILDERNESS SIERRA arrives as a focused response to shooters who demand a sporter-style rifle with real adjustability and field-ready features.

This rifle is engineered for hunters and precision shooters who value a classic look with modern tools: a fluted 4140 CrMo steel barrel in a No. 5 taper, threaded 5/8-24 to accept the included Omni Muzzle Brake, paired with a Bergara Sporter stock that features an adjustable comb and supplied 1/4″ LOP spacers to fine tune length of pull. Price sits at $1,042.99, placing it squarely in a sweet spot for shooters who want performance without excess.

Design and Build: Materials that matter

The Sierra’s barrel is 4140 CrMo steel, fluted for improved cooling and weight savings while keeping stiffness in the No. 5 taper profile. That taper gives a balance between quick handling and rigidity for accurate groups. Threaded 5/8-24 muzzle threads come stock with an Omni Muzzle Brake, allowing meaningful recoil mitigation for follow-up accuracy and less shooter fatigue in the field.

Stock, Ergonomics, and the Adjustable Comb

Ergonomics are the Sierra’s headline feature. The Bergara Sporter stock includes an adjustable comb that lets you dial cheek height for perfect eye-to-scope alignment. Whether you run a low-mounted hunting setup or a tall shrouded reticle for glassing, the adjustable comb is a small piece of hardware that yields large gains in consistent head position.

Length of Pull (LOP) tuning

Included 1/4″ LOP spacers let shooters fine tune the rifle’s fit. That level of adjustability is crucial for hunters who may layer clothing across seasons or for shooters who share the rifle across multiple users. Rather than guessing at aftermarket spacers, the Sierra ships ready to fit.

Magazine and Floorplate Options

The rifle’s M5 bottom metal cutout provides flexibility: use AICS-style magazines for higher capacity during extended range sessions, then switch back to the M5 hinged floorplate for secure, snag-free operation in hunting scenarios. The standard M5 hinged floorplate offers the security and simplicity many field shooters prefer, while the AICS option is great for maximizing on-target time during practice and competition.

Barrel Profile and Muzzle Device

The fluted 4140 CrMo barrel reduces weight without sacrificing the harmonic stability shooters need for consistent accuracy. The Omni Muzzle Brake included with the threaded 5/8-24 setup reduces felt recoil and muzzle rise, making it easier to recover for follow-up shots—an important trait for quick, ethical shot placement on game or timed precision strings at the range.

Mounting and Optics Considerations

The Sierra’s sporter stock and barrel contour give a stable platform for most hunting and precision optics. The adjustable comb helps get your eye over the optic so you can maintain a proper cheek weld and sight picture. As a best practice, pair the rifle with a medium-height scope mount that keeps your head position natural and repeatable.

View product details and pricing and inspect the geometry to match your preferred optic height.

Who the Sierra is best for

This rifle suits the hunter who prefers a sporter silhouette but wants modern performance and adjustability. It’s ideal for a shooter who moves between public range practice and backcountry stands, or for families that want a platform friends and relatives can adjust and shoot comfortably. The inclusion of both AICS magazine compatibility and an M5 floorplate makes it versatile for seasonal shifts in how you use your rifle.

Field Use and Maintenance

Field-maintenance remains straightforward: clean the fluted barrel as you would any steel sporter barrel, and keep the adjustable comb hardware lightly greased and torqued to spec. The threaded muzzle requires the same care as any muzzle device—check for proper torque and alignment after rough travel or knocks. The Sierra’s M5 floorplate is durable and user-friendly, designed for decades of service with minimal fuss.

Check current availability and confirm stock before heading to the range—retailers move fast on rifles that blend field practicality with precision-ready features.
