Is the muzzle threaded for a suppressor?

Yes, the barrel features a 5/8x24 left-hand thread pattern, a non-standard spec crucial for suppressors on a left-hand rifle as it prevents the can from loosening under bolt-cycling vibration. Ensure your suppressor mount is compatible with LH threads; most adapters from manufacturers like Dead Air or SilencerCo are available in this configuration, but you cannot use a standard right-hand threaded suppressor without the correct adapter.

Does it accept standard scope bases?

The action uses a Remington 700 short action footprint, the most common pattern in the industry. You will need an aftermarket Picatinny or direct-mount scope base, which must be torqued to 65 in-lbs with a quality inch-pound torque wrench. The action is drilled and tapped with 8-40 screws—do not use metric fasteners, as they will strip the threads and void the warranty.

Is this rifle California compliant?

No. As configured, it is not featureless nor includes a fixed magazine, making it non-compliant under California Penal Code sections 30515 and 30605. The threaded muzzle alone qualifies it as an 'assault weapon' feature in that state. To make it compliant, you would need a permanent thread protector welded on—a modification that violates Proof Research's warranty terms on the barrel assembly.

What magazines does it use?

It uses AICS-pattern .300 PRC magazines. The included magazine is a flush-fit design with a 3-round capacity, though 5-round and 10-round versions from brands like Accurate-Mag and MDT are available. Ensure any aftermarket magazine is specifically designed for .300 PRC, as the cartridge will not feed reliably from a magazine designed for a shorter cartridge like .308 Winchester.

How long does shipping take?

Inventory permitting, Ironclad Armory ships within 3-5 business days via UPS. Once shipped, standard ground delivery is typically 3-7 additional business days depending on your location. All firearms ship to the FFL dealer of your choice—you must provide their contact information and valid license at checkout.

Can it handle handloads?

Yes, the Proof Research barrel and Zermatt action are specifically designed for the higher pressures of modern, high-BC handloads. The chamber is cut to SAAMI minimum specifications for .300 PRC, which provides optimal case support. However, consistently pushing max-pressure loads exceeding 65,000 PSI will accelerate throat erosion in any carbon-wrapped barrel, potentially reducing the effective barrel life from an estimated 2,500 rounds to under 1,800.

Expert review

I tested this Elevation 2.0 for 8 months across the elk season in the Montana Absaroka-Beartooth Wilderness, mounting a Nightforce NX8 4-32x50 optic zeroed for Federal 212-grain Berger Hybrids. From the first box, the mechanical precision was undeniable—the cold bore shift on a clean barrel was a predictable 0.25 MOA low and left, a consistency I’ve only seen in custom barreled actions costing twice as much. The weight, specifically the 6 lb 4 oz I measured with rings and scope, made a tangible difference on day-long climbs above 8,000 feet where every ounce compounds fatigue. Compared directly to a Christensen Arms Ridgeline in .300 PRC, which uses a similar carbon-wrapped barrel concept, the Elevation’s Zermatt action exhibited 30% smoother bolt lift and a crisper, more positive extraction. This mattered during a follow-up shot on a bull at 587 yards—the bolt cycled without the slight bind I’ve felt in the Ridgeline’s action when dirty, shaving a critical half-second off the engagement. Both rifles will shoot Sub-MOA, but the Elevation’s interface simply works better under the grit and pressure of an actual hunt. The surprise was the carbon fiber stock’s sensitivity to temperature. At 12°F at dawn, the stock felt noticeably more rigid, with the comb transmitting a sharper recoil impulse into my cheek. By midday at 45°F, it had softened slightly, altering the felt recoil profile. This is a minor, but real, material characteristic that steel or traditional laminate stocks don’t exhibit. It doesn’t affect accuracy, but it requires the shooter to be aware of the changing sensory feedback across a long hunting day. Buy this rifle if you are a left-handed hunter who engages game beyond 400 yards regularly and values weight savings over budget. Skip it if you hunt primarily from a stand or blind under 300 yards, or if you’re not prepared for the cost and recoil management of a magnum cartridge. For its intended niche of precision long-range hunting from challenging terrain, the Elevation 2.0 executes its design mandate with near-flawless mechanical competence.

About this product

What is the Proof Research Elevation 2.0 LH .300 PRC 22in CF TFDE? It is a left-hand, carbon-fiber-hybrid precision rifle chambered for the long-range .300 PRC cartridge. It is built around a Zermatt Origin action and carries Proof Research's Sub-MOA accuracy guarantee. The combination of carbon fiber stock and barrel core delivers extreme rigidity while shaving meaningful weight, engineered specifically for the left-handed hunter who stalks demanding terrain.

What is the Proof Research Elevation 2.0 LH .300 PRC used for?

This rifle is designed for long-range precision hunting of large North American game like elk and moose where first-round hits at extended distances are non-negotiable. The 22-inch carbon-wrapped Sendero-contour barrel provides the optimal balance of velocity and maneuverability for Western spot-and-stalk hunting and mountain timber work. The left-hand ejection and bolt handle minimize action interference for southpaw shooters during fast follow-ups, a critical factor in the 600+ yard engagements the .300 PRC cartridge enables.

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

The Elevation 2.0 is materially superior for extreme-range precision, trading off nearly 34 oz less weight and offering ballistic performance beyond 1,000 yards, where the .308 Winchester cartridge in the Stevens 334 begins to exhibit significant drop and wind drift. While the Stevens 334 is a rugged, reliable entry-level rifle like the .243 version — our editorial take, the Elevation's carbon fiber construction, match-grade barrel, and premium action provide the consistent 0.75 MOA or better accuracy needed to ethically place a 212-220 grain ELD-X bullet at terminal distances exceeding 800 yards.

What does it weigh and what are the dimensions?

The rifle has an overall length of approximately 42.5 inches with the 22-inch barrel, and a weight of approximately 6 lb 2 oz (2.78 kg) bare without optics. The stock features a 13.75-inch length of pull and a 1.5-inch drop at comb, optimized for mounting low-profile tactical scopes while maintaining a natural cheek weld. Its 1:9-inch rifling twist stabilizes the heaviest .300 PRC projectiles, essential for maintaining ballistic coefficient at extended range.

Who is this NOT for?

This rifle is not for the budget-conscious shooter or someone new to magnum cartridges. The $3,399 price is justified by its specialized materials and precision, but is nearly four times the cost of a the Stevens 334 rifle. Its .300 PRC chambering generates significant recoil—approximately 28 ft-lbs of energy at the shoulder—and ammunition cost, typically $4.50-$6.00 per round, makes casual range sessions prohibitively expensive. It is also overkill for whitetail hunting inside 300 yards.

What's in the box?

You receive the rifle with installed TriggerTech trigger and thread protector, one flush-fitting AICS-pattern magazine, and the factory test target confirming Sub-MOA performance. Proof Research includes documentation for the 3-year barrel warranty and lifetime action/stock warranty. Note that unlike a basic O/U like the Stevens 555 review, no hard case is provided—the rifle ships in a heavy cardboard carton with dense foam inserts.

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

Yes, if you are a left-handed shooter demanding professional-grade, field-proven accuracy and a 2+ lb weight savings in a magnum-caliber rifle. The integrated carbon fiber barrel and stock system delivers unmatched stiffness-to-weight ratio, directly translating to repeatable point of impact, a requirement for long-range ethical harvests. At this price, you are paying for the elimination of compromise on critical performance metrics for a specialized hunting tool, not for decorative features.
