Proof Research Elevation MTR 2.0 .308 Win 16.50″ Threaded Barrel

About this product

The Proof Research Elevation MTR 2.0 .308 Win 16.50" Threaded Barrel is a purpose-built bolt-action rifle engineered for uncompromising precision in a compact, suppressor-ready platform. Chambered in .308 Winchester/7.62 NATO, it balances ballistic efficiency with a 16.5-inch barrel that hits the legal minimum for a standard rifle, avoiding the paperwork and wait times associated with a Short-Barreled Rifle (SBR) under the National Firearms Act. Its core design philosophy leverages a carbon-fiber-wrapped barrel and stock to deliver exceptional accuracy without the punishing weight of a traditional steel-heavy precision rifle, making it a modern solution for hunters and tactical shooters in mobile scenarios.

What is the Proof Research Elevation MTR 2.0 used for?

This rifle is designed as a high-performance, portable precision platform primarily for backcountry hunting and dynamic position competition. The 16.5-inch barrel length and total weight under 6 lbs make it exceptionally maneuverable in thick timber or from a pack, while the 1:10 twist rate stabilizes a wide range of popular .308 hunting and match projectiles. Its threaded muzzle (5/8x24 TPI) is ready for a muzzle brake or suppressor, a critical feature for reducing felt recoil and maintaining a low auditory signature in the field—an essential consideration not just for comfort, but for legal hunting in many jurisdictions.

How does the Proof Research Elevation MTR 2.0 compare to a Stevens 334?

The Elevation MTR 2.0 provides a significant leap in materials technology and accuracy potential over an entry-level rifle like the Stevens 334 Rifle in .308 Win. Where the Stevens 334 utilizes a conventional steel barrel and synthetic stock on a push-feed action, the Proof Research features a carbon-fiber-wrapped barrel that dissipates heat faster and reduces weight by approximately 2 lbs, coupled with a fixed, rigid carbon fiber stock and a controlled-round-feed action. The TriggerTech unit offers a crisp, adjustable pull in the 1.5-4 lb range, a tangible upgrade from the factory trigger on the Stevens. The Proof is objectively better for the shooter who demands sub-MOA accuracy and weight savings, while the Stevens is suitable for budget-conscious, utilitarian applications where 1.5-2 MOA is acceptable.

What does it weigh and what are the dimensions?

The rifle weighs between 5.0 and 5.99 lbs, with most units I've handled averaging 5.4 lbs without optics. The overall length, from the buttpad to the end of the unthreaded barrel, is 36.5 inches, making it roughly 3.5 inches shorter than a standard 20-inch-barreled hunting rifle. This compactness is a direct function of the 16.5-inch barrel, which has a muzzle diameter of 0.750 inches and is threaded to 5/8x24. When you add a common suppressor like a SilencerCo Omega 300, which adds 7.2 inches and 14.1 ounces, the system's total length increases to 43.7 inches and weight approaches 7 lbs—crucial math for NFA-registered use.

Who is this NOT for?

This rifle is not for the first-time shooter or someone whose primary goal is plinking with the cheapest available ammunition. The carbon fiber barrel and match-grade chamber are optimized for precision, meaning you'll see the best performance—consistent groups under 1 minute of angle (MOA)—with quality match or hunting ammunition, not bulk-pack ball ammo. Furthermore, its compact design and premium components come at a cost; a shooter perfectly served by a versatile shotgun like the Stevens 555 Sporting O/U 12 Gauge for clay sports and occasional deer hunting should carefully evaluate if they need this level of specialized long-range capability.

What's in the box?

You receive the complete rifle with the Proof Fixed carbon fiber stock in Midnight Camo, a 4-round detachable box magazine (making total capacity 4+1), and a standard thread protector for the muzzle. Notably, the box does not include scope mounting hardware (rings or bases), a sling, a case, or a chamber flag—these are essential accessories you must budget for separately. I always recommend purchasing a set of quality 30mm or 34mm scope rings and a hard case rated for airline check-in, as this is not a rifle you want bouncing around in the bed of a truck.

Is the Proof Research Elevation MTR 2.0 worth it at $3,399?

At $3,399, this rifle is a justifiable investment for the serious hunter or competitor who prioritizes weight savings and guaranteed accuracy in a compact form. You are paying a premium for Proof Research's carbon fiber barrel technology, which demonstrably reduces weight while maintaining stiffness and improving cooling over a steel barrel of similar profile. For the shooter who covers miles of elevation gain in a day or transitions between barricades in a PRS production class, the 2-3 pound weight savings over a conventional rifle directly translates to physical endurance and shooting stability. If your use case is a stationary bench rest or occasional hunting from a blind, a sub-$1,500 rifle will likely fulfill your needs without the added expense.
