About this product
The Bergara HMR Pro 300 Win Mag 26in Threaded 5rd is a precision bolt-action rifle engineered for repeatable, long-range field performance under demanding conditions by combining a premium stainless barrel with an integrated synthetic chassis and suppressor-ready threading. It represents the practical evolution of target rifle architecture into a single platform durable enough for mountain hunting yet mechanically precise enough for competition-style shooting. This rifle acknowledges the modern shooter's need for a single instrument capable of bridging multiple disciplines, which is why its specifications lean toward the heavy, stable, and customizable.
What is the Bergara HMR Pro used for?
This rifle is designed for precision long-range field shooting where repeatable accuracy and suppressor use are priorities. The 26-inch barrel, 1:10 twist rate, and 5/8-24 muzzle threads are optimized for stabilizing and launching heavy .300 Win Mag projectiles (190-220 grain) at distances beyond 800 yards, especially when paired with a muzzle brake or suppressor. Its 11.8-pound weight and adjustable stock create a stable firing platform ideal for deliberate shots from a bipod or supported position, whether that's a competition stage, an alpine hunt for elk, or extended tactical training.
How does the Bergara HMR Pro compare to the Stevens 334 .308 Win?
The Bergara HMR Pro offers superior out-of-the-box precision and suppressor-ready features compared to the Stevens 334, but at more than double the price and weight. Where the Stevens 334 is a 7.3-pound, $700 utility rifle chambered in .308 Win with a 20-inch non-threaded barrel for general-purpose use, the Bergara HMR Pro is an 11.8-pound, $1700 specialist tool with a threaded 26-inch premium barrel, a fully adjustable chassis, and a match-grade trigger for dedicated long-range work. The Bergara is definitively better for shooters who need sub-MOA consistency and the option to mount a suppressor, while the Stevens 334 is the better choice for budget-conscious hunters needing a lightweight, reliable carry rifle.
What does it weigh and what are the dimensions?
The rifle weighs 11.8 pounds (5.35 kg) unloaded and without optics, and measures 46.5 inches (1181 mm) in overall length. This substantial weight comes primarily from the 26-inch, medium-contour stainless steel barrel and the fiberglass-reinforced synthetic stock with its integrated aluminum mini-chassis. The width across the forend is 2.4 inches (61 mm), and the length of pull is adjustable from 13.5 to 14.5 inches (343 to 368 mm) via included spacers, accommodating a wide range of shooter builds and winter clothing layers.
Who is this NOT for?
This rifle is not for budget-conscious first-time buyers, lightweight mountain hunters prioritizing packability over precision, or shooters sensitive to .300 Win Mag's substantial recoil and ammunition cost. The $1700 price tag is an entry fee for serious long-range capability, and the 11.8-pound weight makes it burdensome for spot-and-stalk hunting over steep terrain where every ounce matters. If your primary need is a light, affordable, general-purpose rifle for shots inside 300 yards, consider a model like the Stevens 334 in .243 Win instead.
What's in the box?
You receive the complete rifle, one 5-round AICS-pattern detachable steel magazine, a set of three buttstock spacers for length-of-pull adjustment, a hex key set for adjusting the cheek piece and trigger pull weight, and the owner's manual with torque specifications for scope base installation. Notably absent are any thread protectors or muzzle devices; you must supply your own 5/8-24 thread protector, muzzle brake, or suppressor mount, which is a common but frustrating omission in this price segment that adds $30-$150 to your initial setup cost.
Is the Bergara HMR Pro worth it at $1699.99?
Yes, but only if your shooting discipline explicitly requires the combination of a precision .300 Win Mag chambering, a 26-inch threaded barrel, and a fully adjustable chassis system that this rifle delivers. You are paying for Bergara's barrel-making reputation, the proven TriggerTech trigger, and the rigid bedding of the mini-chassis—components that would cost significantly more to assemble separately on a custom action. At this price point, you are bypassing the entry-level rifle market entirely and investing in a tool that removes mechanical inconsistency as a variable, allowing you to focus solely on shooter skill and ammunition selection.

Pros & cons
What works
- 1:10 twist 26-inch premium Bergara barrel – delivers consistent sub-MOA accuracy with heavy .30 cal projectiles.
- Fully adjustable synthetic stock – length of pull adjusts from 13.5in to 14.5in and cheek piece has 1.5in of vertical travel.
- Suppressor-ready 5/8-24 threaded muzzle – allows direct mounting of brakes or cans without gunsmithing.
- TriggerTech Frictionless Release trigger – user-adjustable from 1.5 to 4 pounds of pull weight.
Trade-offs
- No thread protector or muzzle device included – a $30-$150 oversight at this price point.
- Heavy 11.8-pound weight – prohibitive for extended carry hunting or dynamic shooting positions.
- .300 Win Mag ammunition cost – expect to pay $3.50-$5.00 per round for quality match-grade fodder, making practice expensive.

Frequently asked questions
- What suppressor mount thread pattern does it use?
- The muzzle is threaded 5/8-24 TPI, which is the standard for .30 caliber rifles like the .300 Win Mag. This directly accepts many popular muzzle devices and suppressor mounts from companies like SilencerCo (ASR), Dead Air (KeyMo), and Q (Cherry Bomb). You will need to purchase a thread protector or muzzle device separately, as one is not included.
- Will it accept aftermarket AICS magazines?
- Yes, the action is milled to accept standard AICS-pattern short-action magazines. The included magazine is a 5-round steel version, but most aftermarket polymer or metal AICS magazines from brands like Magpul or Accurate Mag will fit, provided they are for the .300 Winchester Magnum cartridge specifically. Always test fit and function with your chosen magazines before relying on them in the field.
- What scope bases does it accept?
- The action is drilled and tapped for Remington 700 short-action footprint bases, which is the industry standard for this platform. Use bases with a 6-48 screw thread pattern and torque them to 15-20 in/lbs with a quality inch-pound torque wrench. I recommend using a thread-locking compound like Vibra-Tite VC-3 on the screws to prevent loosening under heavy recoil.
- How long is the shipping and handling time?
- As an 'Online Only' item, this rifle ships directly from our distributor network. Processing and transfer to your selected FFL typically takes 3-5 business days. Once shipped via a contract carrier, ground transit adds another 3-7 business days depending on your location. You will receive tracking information as soon as the item leaves our logistics center.
