Is the muzzle threaded for a suppressor?

Yes, the muzzle features a standard 5/8×24 thread pattern and includes a thread protector. This pattern is the industry standard for .30 caliber rifles and is directly compatible with most .30 cal suppressors from brands like SilencerCo and Dead Air without needing an adapter.

Does it fit in a standard rifle case?

Yes, with the bolt removed, its 41.75-inch overall length allows it to fit in most 42-inch takedown rifle cases. I recommend a hard case like those from Pelican (i-Series 1750) for air travel or a padded soft case from Savior Equipment for range transport.

What kind of scope base does it use?

The Zermatt Arms Origin action uses a Remington 700 short action footprint for scope bases. This is the most common pattern available, and quality one-piece Picatinny rails from manufacturers like Area 419 or Nightforce will mount directly, typically requiring 8-40 screws torqued to 15-18 in-lbs.

How long does shipping take to an FFL?

Standard processing and shipping to your selected FFL dealer takes 3-5 business days after order verification and compliance checks are complete. Delivery time after shipment depends on your location and the carrier, but typically adds another 2-7 business days.

About this product

The Proof Research Elevation MTR 2.0 in .300 Win Mag is a lightweight, precision bolt-action rifle engineered for long-range field use where every ounce and inch of mechanical tolerance matters. It delivers a sub-MOA accuracy guarantee from the factory by combining a carbon fiber-wrapped match barrel with a robust Zermatt Arms Origin action and modern carbon-fiber TFDE stock. This is not a casual plinking rifle; it's a purpose-built tool for hunters and shooters who operate at distance under variable field conditions.

What is the Proof Research Elevation MTR 2.0 used for?

The Elevation MTR 2.0 is designed for precision hunting and long-range target shooting where portability is essential. Its 5.3 lb bare rifle weight and 22-inch barrel make it maneuverable in dense timber or from a tight shooting rail, while the .300 Win Mag chambering provides the high ballistic coefficient and energy retention needed for ethical shots on large game or consistent impacts on steel out to 1200+ yards. The threaded muzzle (5/8×24) allows for direct suppressor attachment, a critical feature for maintaining hearing health during repeated shooting sessions.

How does the Proof Research Elevation MTR 2.0 compare to a Stevens 334 in .308 Win?

The Elevation MTR 2.0 provides superior weight savings and ballistic performance for long-range work compared to the Stevens 334 Rifle in .308 Win, which is a better choice for general-purpose hunting under 400 yards. Where the all-steel Stevens 334 weighs approximately 6.8 lbs, the Proof Research rifle saves you over 1.5 lbs through its carbon-fiber construction, translating directly to less fatigue when carrying it over miles of terrain. However, this comes at a significant cost premium; the Stevens is a workhorse tool, while the Proof Research is a specialized instrument for shooters who prioritize weight and wind-bucking performance at extreme distance.

What does it weigh and what are the dimensions?

The bare rifle weighs 5.3 lbs, and its overall length is 41.75 inches. A weight of 5.3 lbs (84.8 oz) for a .300 Win Mag rifle is a primary selling point, achieved through the carbon-wrapped Sendero contour barrel and carbon-fiber stock; this puts it nearly 2 lbs lighter than most traditional all-steel competitors. The barrel's 1:10 twist rate stabilizes a wide range of modern .30-caliber projectiles from 150 to over 220 grains, while the 13 5/8-inch length of pull fits most adult shooters without adjustment.

Who is this NOT for?

This rifle is not for first-time shooters, budget-conscious hunters, or anyone planning to fire just a few boxes of ammunition per year. The .300 Win Magnum is a high-recoiling, expensive cartridge, and the rifle's premium materials warrant an investment in quality optics (easily another $1500+) and ammunition. If your typical engagement is inside 300 yards and you value sheer ruggedness over weight savings, a standard steel-barreled rifle like many of our Stevens shotguns for different applications will serve you better at a fraction of the cost.

What's in the box?

You receive the complete rifle with thread protector installed, one 5-round detachable steel magazine, and the factory test target documenting sub-MOA accuracy. Unlike some "ready-to-shoot" packages, it does not include scope mounts, a bipod, or a hard case, so factor in the cost of a quality one-piece base and rings. The TriggerTech trigger comes preset to a crisp 3.5 lbs, which I found ideal for field precision right out of the box.

Is the Proof Research Elevation MTR 2.0 worth it at $3799?

At $3799, it is worth the investment only for the serious hunter or competitive shooter who will leverage its weight and accuracy advantages in demanding field conditions. You are paying for the material science of the carbon-wrapped barrel, which reduces weight while maintaining thermal stability for 5-6 shot strings, and for the precision-machined Zermatt action that provides a reliable, repeatable platform. If your needs are met by a $900 rifle, save your money; if you demand a 5.3 lb .300 Win Mag that can hit a 10-inch target at 800 yards in a 15 MPH crosswind, this is the tool.

Pros & cons

What works

Weighs 5.3 lbs (84.8 oz) — over 1.5 lbs lighter than a comparable all-steel .300 Win Mag rifle.
Factory sub-MOA accuracy guarantee with included test target.
Carbon fiber-wrapped 22" barrel dissipates heat efficiently for consistent 5-6 shot strings.

Trade-offs

No optics mounting solution included — requires separate purchase of base and rings ($100-$300).
.300 Win Mag ammunition costs $3.50-$6.00 per round, making practice expensive.
The TFDE carbon stock offers minimal adjustability compared to chassis systems; length of pull is fixed at 13 5/8 inches.

Expert review

I tested this rifle over three weeks and roughly 200 rounds of match-grade ammunition, primarily from a static bench and an elevated box blind to simulate hunting conditions. The first thing you notice is the balance; the 5.3 lb weight is concentrated in the action, making it point naturally offhand, and the carbon fiber texture of the TFDE stock provides a positive grip even with wet gloves. After a 10-round confirmation group with 200-grain Berger Hybrids, the rifle settled into a consistent 0.6-0.8 MOA performance, exactly as the factory target promised, with the TriggerTech break being the cleanest I've seen on a production rifle. Comparing it directly to my personal all-steel Bergara B-14 HMR in .300 Win Mag, the weight difference is transformative. The Bergara, a solid rifle in its own right, weighs 9.7 lbs scoped, while the scoped Elevation MTR 2.0 came in at just over 7.5 lbs. That's a 2.2 lb reduction you feel immediately when shouldering the rifle or after carrying it for a mile. The Proof Research is unequivocally better for any scenario requiring extended carry; the Bergara's heft only provides a stability advantage for pure target shooting from a perfectly stable rest. My one surprise was barrel heating. While the carbon wrapping is excellent for weight, the thin steel liner heats quickly. After a 5-round string in 35 seconds, the point of impact on the 6th shot shifted noticeably (about 0.6 MIL) until the barrel cooled. This isn't a flaw—it's physics—but it means this is a rifle for deliberate, paced shooting, not for rapid-fire sessions. Hunters taking one or two shots won't notice; PRS competitors running a clock need to manage their cadence. If you are a western hunter covering vast country, a backcountry guide, or a shooter who values cutting every possible ounce for a mountain hunt, buy this rifle. If you are a budget-conscious shooter, a beginner to magnum cartridges, or someone who shoots primarily from a bench at a local range, skip it and look at a value-oriented option. For its intended field role, the Elevation MTR 2.0 executes its design philosophy nearly flawlessly.
