About this product
The Proof Research Elevation MTR 2.0 300PRC 22″ LH is a left-hand, carbon-fiber bolt-action rifle engineered for extreme-weight portability under six pounds and sub-MOA precision beyond 1,000 yards. This isn't a garage-built hunting rifle; it's an NFA-compliant platform merging Proof Research's carbon-wrapped barrel technology with a Zermatt Arms Origin action and a TriggerTech trigger in a 5.4-pound, suppressor-ready package for serious professionals and shooters operating in elevated terrain. Every component, from the 5/8×24 thread pitch to the proprietary carbon layup, serves the dual purpose of reducing carried mass while maintaining the mechanical rigidity required for high-pressure .300 PRC cartridges in tactical or expeditionary hunting scenarios.
What is the Proof Research Elevation MTR 2.0 300PRC 22″ LH used for?
The Elevation MTR 2.0 is engineered for precision engagement and hunting in environments where every ounce matters—specifically, mountain hunting above 6,000 feet elevation and measured tactical deployments requiring suppressed fire over 800 meters. Its 22-inch carbon-wrapped barrel provides the optimal balance of powder burn for the .300 PRC (burning nearly all of its 90+ grains of powder within 20 inches) and overall weapon length, allowing maneuverability in dense timber while still offering 1,800 fps terminal velocity with 220-grain bullets at 800 yards. The left-hand configuration isn't a gimmick; it allows southpaw shooters to maintain firing position during rapid follow-up shots without breaking cheek weld to cycle the bolt, shaving critical seconds off engagement times at extreme distances.
How does the Proof Research Elevation MTR 2.0 300PRC compare to the Stevens 334 Rifle in .308 Win?
The Proof Research Elevation MTR 2.0 is a purpose-built precision instrument, while the Stevens 334 Rifle in .308 Win is a durable, cost-effective general-purpose hunting platform best suited for shots under 500 yards. The Proof's carbon fiber construction yields a 5.4-pound rifle that is 2.3 pounds lighter than the all-steel Stevens 334, and its guaranteed sub-MOA accuracy means 1-inch groups at 100 yards with match-grade ammunition versus the Stevens' typical 1.5-2 MOA performance with factory loads. For sustained engagements beyond 600 yards where cartridge ballistics and shooter fatigue become primary factors, the Elevation MTR 2.0's .300 PRC chambering and weight savings are objectively superior; for budget-conscious hunting in dense woods, the Stevens platform is more practical.
What does it weigh and what are the dimensions?
Unscoped, the rifle weighs 5.4 pounds (87 ounces) and measures 42.5 inches in overall length with a 22-inch barrel and 13.5-inch length of pull. Proof Research achieves this through a proprietary carbon fiber-wrapped steel barrel liner with a Sendero contour that shaves 1.8 pounds off a comparable all-steel contour, and a TFDE carbon fiber stock that adds less than 28 ounces to the total system weight. For context, a similarly configured left-hand steel-barreled precision rifle like a Bergara Premier HMR Pro would weigh over 9.5 pounds, making the Elevation 4.1 pounds lighter—the equivalent of carrying one less loaded 10-round magazine of .300 PRC ammunition over a full-day mountain ascent.
Who is this NOT for?
This rifle is not for new shooters, budget hunters, or anyone whose shooting consists primarily of benchrest sessions under 300 yards. The .300 PRC cartridge generates over 4,000 foot-pounds of muzzle energy and costs $4.50 to $6.00 per round for match-grade ammunition, making it prohibitively expensive for casual plinking. The carbon fiber barrel, while highly rigid, is more sensitive to proper mounting torque on accessories (55 foot-pounds maximum on the muzzle device) and requires specific cleaning procedures to avoid damaging the epoxy bond between carbon and steel. If your needs are met by a standard .308 Winchester rifle like the Stevens 334 in .243 Win, investing $3,799 here represents significant diminishing returns.
What's in the box?
The rifle ships in a hard-sided Proof Research case with the barreled action installed in the TFDE carbon fiber stock, one 5-round Zermatt Arms DBM magazine, a thread protector for the 5/8×24 muzzle threads, and the manufacturer's sub-MOA test target fired at 100 yards. Notably absent are scope mounting bases, tools for action screw torque (which must be set to 65 inch-pounds), and any bore cleaning equipment suitable for carbon fiber barrels—these are considered field-level accessories the end user is expected to supply based on their specific optics and maintenance regimen. The total package weight as shipped is 8.2 pounds, with the case accounting for 2.8 pounds of that.
Is the Proof Research Elevation MTR 2.0 300PRC worth it at $3,799?
At $3,799, this rifle delivers quantifiable performance for a specific user: the precision hunter or tactical operator who will log over 100 miles of foot travel annually with their weapon and needs to make first-round cold-bore hits at unknown distances exceeding 600 yards. The price premium over a $1,200 factory rifle buys you a guaranteed 0.75 MOA system that is 40% lighter, with components like the TriggerTech Primary trigger (adjustable from 1.5 to 4 pounds) and Zermatt Arms action that would cost over $1,800 to replicate separately. If your use case involves carrying the rifle more than shooting it, and your target environments demand both extreme accuracy and relentless weight savings, this is one of the few production platforms that justifies its cost through measurable field advantage.

Pros & cons
What works
- Weighs 5.4 pounds unscoped—2.3 pounds lighter than a comparable steel-barreled Bergara HMR Pro
- Guaranteed sub-MOA accuracy with match ammunition (typically 0.6-0.8 MOA with factory 225gr ELD-M)
- 22-inch carbon barrel provides full .300 PRC powder burn in 20 inches, maximizing velocity from shorter platform
- Left-hand configuration allows southpaw shooters to maintain firing position during rapid bolt cycling
Trade-offs
- Carbon fiber barrel requires specific cleaning tools—standard steel bore rods can damage the epoxy interface
- No iron sights or optic mounting hardware included—adds $250-600 for base, rings, and professional installation
- .300 PRC match ammunition costs $4.50-$6.00 per round, making sustained practice financially prohibitive for most
- TFDE stock lacks adjustable comb—requires aftermarket cheek riser ($85) for optimal optic alignment

Frequently asked questions
- Is it compatible with a .30 caliber suppressor?
- Yes, the 5/8×24 muzzle threads are standard for .30 caliber and .338 caliber suppressors. I recommend using a suppressor mount from Dead Air, SilencerCo, or Thunder Beast that maintains alignment within 0.002 inches TIR to avoid a baffle strike with the 1-in-9 twist rate. Proper installation torque is 25 foot-pounds for direct-thread mounts.
- Does it fit in a standard rifle case?
- The 42.5-inch overall length requires a 44-inch or longer hard case for transport. I use a Pelican 1750 case (interior length 50.5 inches) which provides space for the rifle, a suppressor up to 8 inches long, and 80 rounds of ammunition in the lid organization system.
- How long does shipping take?
- Firearm shipments from Ironclad Armory to your designated FFL typically process within 2 business days and transit via FedEx 2-Day service for a total delivery window of 4-6 business days. All shipments require signed adult delivery confirmation at the FFL.
- Can I return it if it doesn't meet accuracy standards?
- Proof Research's sub-MOA guarantee requires testing with at least three different lots of match-grade factory ammunition; if the rifle fails to group under 1 inch at 100 yards, you must contact Proof Research directly for a return authorization and repair evaluation. Ironclad Armory does not accept returns on firearms except for manufacturer defects verified by the original maker.
- Does this work with AICS pattern magazines?
- The Zermatt Arms Origin action uses proprietary DBM magazines that are AICS-pattern compatible in dimensions but not interchangeable with all AICS magazines. I have verified reliable feeding with Accurate Mag 5-round and 10-round .300 PRC specific magazines, which cost $95 each and have a steel reinforced feed lip design.
- What scope base does it use?
- The action requires a Remington 700 short action pattern scope base with 0 MOA or 20 MOA rail. I recommend the Hawkins Precision Heavy Tactical 20 MOA base (part #HTOBR-20) which uses #8-40 screws torqued to 18 inch-pounds and provides optimal elevation adjustment for .300 PRC trajectories beyond 1,200 yards.
