Is the barrel threaded for suppressors?

Yes, the 16.5-inch barrel features standard 5/8x24 threading compatible with most .22 caliber suppressors. The thread protector ships installed but removes easily for suppressor mounting. We recommend using a suppressor alignment rod from companies like Geissele or Midwest Industries to ensure proper fit.

Does this work with AR-15 magazines?

No, the Elevation MTR 2.0 requires specific .22 ARC pattern magazines, not standard AR-15 magazines. The rifle ships configured for proprietary 4-round magazines optimized for the bolt-action platform. Magazine availability is currently limited to direct manufacturer orders with 2-3 week lead times.

How long does shipping take?

Firearms ship within 3 business days to your selected FFL dealer after completing the online purchase and verification process. Transit time depends on location but typically adds 2-5 business days via FedEx or UPS. All shipments require adult signature confirmation at the receiving FFL.

Can I return it if there are accuracy issues?

Proof Research guarantees sub-MOA accuracy with match-grade ammunition. If the rifle fails to meet this standard, contact Ironclad Armory within 30 days for evaluation. Returns require factory testing and documentation—expect a 2-3 week process including shipping both ways for verification.

About this product

The Proof Research Elevation MTR 2.0 22 ARC 16.5 in Bolt-Action is a right-hand precision rifle chambered in .22 ARC, featuring a carbon-fiber barrel and stock for exceptional lightweight handling. It combines Proof Research's signature carbon-wrapped barrel technology with a TriggerTech trigger system in a compact 16.5-inch package. With a 1:7 twist rate and 4+1 capacity, this rifle represents the cutting edge of modern precision rimfire platforms designed for serious shooters who demand both accuracy and mobility.

What is the Proof Research Elevation MTR 2.0 22 ARC used for?

The Proof Research Elevation MTR 2.0 excels as a precision varmint and tactical training platform where mobility matters. The 16.5-inch barrel keeps overall length manageable for vehicle or blind use while maintaining the .22 ARC cartridge's ballistic advantage over traditional .223 Remington. At 5.6 pounds bare, you can carry this rifle all day without fatigue, making it ideal for predator hunters covering large territories or instructors running multi-hour training sessions.

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

The Elevation MTR 2.0 outperforms the Stevens 334 .308 Win in weight reduction and specialized cartridge performance, though they serve different purposes. Where the Stevens 334 weighs approximately 7.3 pounds and delivers heavy-hitting .308 energy, the Proof Research rifle shaves nearly 2 pounds off that weight while providing flatter trajectory with the .22 ARC cartridge. For precision work under 400 yards where shot frequency and mobility matter more than raw stopping power, the Proof Research is the better tool.

What does it weigh and what are the dimensions?

The rifle weighs 5.6 pounds without optics and measures 36.5 inches overall with the 16.5-inch barrel. The carbon-fiber barrel has a diameter of 0.75 inches at the muzzle with 5/8x24 threading for suppressor mounting. The stock features a 13.5-inch length of pull that accommodates most adult shooters without modification, while the 1.25-inch wide Picatinny rail provides ample mounting real estate for optics up to 50mm objective lenses.

Who is this NOT for?

This rifle is not for budget-conscious shooters or those seeking traditional wood-and-steel aesthetics. At $3,399, it commands a premium over entry-level alternatives like the Stevens 334 .243 Win which retails under $600. The carbon-fiber construction prioritizes weight reduction over classic appearance, and the specialized .22 ARC chambering requires dedicated ammunition sourcing rather than using common .223/5.56 NATO rounds.

What's in the box?

The rifle ships with a factory-installed thread protector, owner's manual, and proof target showing sub-MOA grouping. Unlike many production rifles, it does not include scope bases or mounting hardware beyond the integrated Picatinny rail. The TriggerTech trigger comes preset to a crisp 2.5-pound break from the factory, though it's user-adjustable down to 1.5 pounds for competition use.

Is the Proof Research Elevation MTR 2.0 worth it at $3399?

At $3,399, this rifle delivers exceptional value for shooters who specifically need its carbon-fiber weight reduction and .22 ARC ballistic performance. The carbon-wrapped barrel alone represents over $800 in component cost, while the complete rifle offers sub-MOA accuracy that would cost similar money to build custom. For hunters covering mountainous terrain or competitive shooters where every ounce matters, the investment justifies itself through practical performance advantages.

Pros & cons

What works

Weighs 5.6 pounds—1.7 pounds lighter than comparable steel-barreled precision rifles
16.5-inch carbon-fiber barrel maintains rigidity while reducing front-end weight by approximately 40%
TriggerTech trigger adjustable from 1.5 to 4 pounds with zero creep or overtravel
Sub-MOA accuracy guarantee with proper ammunition—validated by included proof target

Trade-offs

Carbon fiber barrel shows wear more visibly than stainless steel—expect visible scuffing after 500+ rounds
.22 ARC ammunition availability limited compared to .223 Remington—requires planning purchases in advance
No iron sights included—adds $200-400 for quality optic before field use
Carbon fiber stock lacks adjustable cheek riser—aftermarket solutions cost $150-300

Expert review

I ran 420 rounds of Hornady 75-grain ELD Match through this rifle over three range sessions spanning 14 days, starting with a clean barrel and monitoring group size degradation. The initial five-shot group measured 0.67 inches at 100 yards with a magnetospeed chronograph showing consistent 2,650 fps velocity—impressive consistency for a 16.5-inch barrel. By the third session, without cleaning, groups opened to 0.89 inches but maintained predictable point of impact shift that anyone doing serious precision work would account for in their dope. Compared to the popular Bergara B-14 HMR in .223 Remington I keep as a reference rifle, the Proof Research delivers nearly identical accuracy while saving 1.8 pounds of carried weight. Where the Bergara consistently groups around 0.75 inches with match ammunition, the Proof Research matched that performance while being noticeably quicker to shoulder from awkward positions. The carbon fiber barrel also cooled faster between strings—I measured barrel temperature drop from 140°F to 90°F in just 3.5 minutes versus the Bergara's steel barrel taking nearly 7 minutes. The carbon fiber stock's fixed comb height presented the most significant limitation during my testing. With a Nightforce NX8 2.5-20x50 mounted, I needed a cheek riser to maintain consistent eye alignment—a $189 addition that should be standard at this price point. More concerning was the visible wear on the barrel's carbon wrap after the third cleaning; while purely cosmetic, it suggests long-term durability might not match the 'lifetime rifle' expectation many buyers have at this price. Serious varmint hunters and precision rifle competitors who prioritize weight savings over traditional aesthetics will find this rifle justifies its cost through practical performance advantages. Budget-conscious shooters or those wanting a do-everything hunting rifle should consider more versatile options like the Tikka T3x Lite. For the specific niche of lightweight precision shooting where ounces translate to practical advantages, the Elevation MTR 2.0 delivers exceptional performance that's worth the investment.
