PROOF Research Elevation MTR FDX Rifle

Mountain Technical Rifle

MTR – Mountain Technical Rifle.

That name perfectly describes what PROOF has created with the Elevation MTR FDX.

Rather than designing another ultralight traditional hunting rifle, PROOF has combined the portability of a premium mountain rifle with the ergonomics and functionality normally associated with a precision tactical platform.

The Elevation MTR FDX is designed for shooters who demand:

✔ Lightweight performance

✔ Precision rifle ergonomics

✔ Long-range capability

✔ PXT carbon fibre barrel technology

✔ Tripod and bipod compatibility

✔ Detachable magazine functionality

✔ Premium components throughout

✔ Adaptability from field to range

The result is a genuine hybrid rifle that doesn’t force the shooter to choose between a rifle that’s comfortable to carry and one that’s comfortable to shoot.

PROOF MTR Carbon Fibre Stock

One of the defining differences between the Elevation MTR FDX and the standard Elevation FDX is its:

PROOF MTR Carbon Fibre Stock

The MTR stock features a:

✔ Slightly raised comb

✔ Near-vertical grip

These features promote a more natural shooting position and greater control behind the rifle.

The raised comb provides improved alignment behind modern precision optics, while the near-vertical grip creates a more relaxed trigger-hand position when shooting prone, from a tripod or from supported field positions.

Benefits include:

✔ Improved head positioning

✔ More natural trigger-hand placement

✔ Better recoil management

✔ Improved positional shooting

✔ Greater comfort behind larger optics

✔ Precision-rifle-inspired ergonomics

This is what gives the MTR FDX its distinct personality compared with the more traditionally configured Elevation FDX.

Splinter Camouflage Finish

The carbon fibre MTR stock is finished in PROOF’s distinctive:

Splinter Camo

The contemporary finish complements the technical nature of the rifle while retaining the premium appearance expected from a PROOF Research platform.

Combined with the exposed carbon fibre barrel and precision components, it gives the MTR FDX an unmistakably modern appearance.

PROOF PXT Carbon Fibre Barrel

At the heart of the Elevation MTR FDX is PROOF Research’s latest:

PXT Carbon Fibre Barrel Technology

PXT represents a fundamental rethink of conventional rifling geometry and twist progression.

By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PROOF designed PXT to reduce the forces generated as the projectile engages the rifling.

Benefits include:

✔ Reduced engraving force

✔ Reduced throat erosion

✔ Less felt torque during firing

✔ Improved recoil control

✔ Better ability to remain on target

✔ Improved consistency

✔ Increased barrel longevity

PROOF reports that in controlled testing, PXT barrels demonstrated 30–100% increases in barrel life before measurable accuracy degradation.

For shooters using modern high-performance cartridges—and particularly those who train regularly with their hunting rifle—the potential increase in useful barrel life is a significant advantage.

Sendero Contour Carbon Fibre Barrel

The MTR FDX uses a:

Sendero Contour PXT Carbon Fibre Barrel

The Sendero profile provides the rigidity expected from a serious precision rifle while PROOF’s carbon fibre construction keeps overall weight remarkably low.

Benefits include:

✔ Excellent barrel rigidity

✔ Reduced overall rifle weight

✔ Excellent thermal characteristics

✔ Improved consistency

✔ Long-range precision capability

✔ Better balance than a traditional heavy steel barrel

This is particularly important on the MTR FDX, where the objective is to deliver precision-rifle performance without turning the rifle into a heavy platform that becomes burdensome in the mountains.

Exceptionally Lightweight

Despite its precision-oriented ergonomics and equipment, the Elevation MTR FDX weighs approximately:

5lb 14oz – 6lb 8oz

or approximately:

2.66kg – 2.95kg

depending on chambering and configuration.

That gives the MTR FDX an unusual combination of genuine mountain-rifle portability and modern precision-rifle functionality.

Benefits include:

✔ Reduced fatigue during long hunts

✔ Easier mountain carry

✔ Better manoeuvrability

✔ Lower overall system weight

✔ More weight allowance for premium optics and accessories

For hunters already carrying optics, tripod, bipod, ammunition, water and a full backcountry pack, reducing rifle weight without sacrificing capability can make a meaningful difference.

Falkor Defense LW7 Action

The Elevation MTR FDX is built around the:

Falkor Defense LW7 Action

The LW7 provides the precision foundation for the rifle while supporting PROOF’s lightweight design philosophy.

Benefits include:

✔ Precision machining

✔ Smooth bolt operation

✔ Excellent rigidity

✔ Reliable field performance

✔ Lightweight construction

✔ Premium action architecture

Paired with the PXT carbon fibre barrel and TriggerTech trigger, the LW7 creates a high-performance foundation for both field and range use.

TriggerTech Trigger

Every Elevation MTR FDX comes equipped with a:

TriggerTech Trigger

TriggerTech has established itself as one of the benchmark trigger manufacturers within the precision rifle industry.

Benefits include:

✔ Crisp trigger break

✔ Minimal creep

✔ Excellent consistency

✔ Predictable shot release

✔ Premium precision rifle performance

On a lightweight precision rifle, consistent trigger control becomes especially important when trying to extract maximum accuracy from difficult field positions.

Hawkins Precision M5 Hunter Bottom Metal

The MTR FDX features:

Hawkins Precision M5 Hunter Bottom Metal

paired with a:

3-Round Hunter Magazine

This gives the rifle detachable-box-magazine functionality while maintaining a compact hunting profile.

Benefits include:

✔ Fast loading and unloading

✔ Reliable feeding

✔ Compact magazine profile

✔ Reduced protrusion beneath the rifle

✔ Premium bottom metal

✔ Hunting-focused functionality

The three-round magazine keeps the rifle streamlined for field use while still providing the convenience of a detachable magazine system.

Salmon River Solutions SRS Combo Rail

Modern long-range hunters increasingly use both bipods and tripods depending on terrain and shooting position.

PROOF addresses this from the factory with the:

Salmon River Solutions SRS Combo Rail

providing both:

ARCA + Picatinny

interfaces.

Benefits include:

✔ Direct ARCA tripod compatibility

✔ Picatinny bipod compatibility

✔ Fast transitions between support systems

✔ Increased field versatility

✔ No need for bulky aftermarket rail systems

This makes the MTR FDX particularly well suited to modern tripod-based hunting techniques.

Built for Tripod Shooting

Combine the MTR stock’s:

Raised comb + near-vertical grip

with the factory:

ARCA interface

and the design intent becomes clear.

The MTR FDX is exceptionally well suited to shooters who increasingly use a tripod as a primary shooting support.

Benefits include:

✔ Stable standing shots

✔ Improved kneeling positions

✔ Better shooting over vegetation

✔ Fast transitions between glassing and shooting

✔ Greater stability on uneven terrain

✔ Improved positional versatility

This is where the MTR FDX begins to separate itself from a conventional lightweight hunting rifle.

20 MOA Pinned Scope Rail

The rifle comes factory equipped with a:

20 MOA Pinned Scope Rail

Benefits include:

✔ Increased usable elevation adjustment

✔ Better long-range capability

✔ Secure mechanical interface

✔ Improved rail stability

✔ Ready for premium dialable optics

The 20 MOA inclination makes the MTR FDX particularly well suited to modern long-range hunting scopes with exposed elevation turrets.

Compact Barrel Configurations

PROOF matches barrel length and twist rate to each factory chambering.

Chambering	Barrel Length	Twist Rate
22 Creedmoor	18″	1:8
6.5 Creedmoor	18″	1:7.5
6.5 PRC	20″	1:7.5
7 PRC	20″	1:8
7 BC	16.5″	1:8
300 PRC	20″	1:9

All configurations utilise the Sendero contour PXT carbon fibre barrel.

These relatively compact barrel lengths help maintain excellent handling characteristics while keeping overall rifle length manageable in steep terrain, vehicles and dense vegetation.

Threaded Muzzle

Every current Elevation MTR FDX configuration features:

5/8″-24 Muzzle Thread

and is supplied with a:

Thread Protector

Benefits include:

✔ Easy muzzle brake installation

✔ Broad muzzle-device compatibility

Elevation FDX or Elevation MTR FDX?

These two rifles share much of the same advanced FDX architecture, but they are designed around different shooter preferences.

Choose the Elevation MTR FDX if:

✔ You prefer a more vertical grip

✔ You want a raised comb behind your optic

✔ You shoot frequently from prone

✔ You regularly shoot from a tripod

✔ You train extensively with your hunting rifle

✔ You want precision-rifle ergonomics

✔ You want one rifle to bridge range and hunting use

✔ You prioritise positional shooting control

Choose the Elevation FDX if:

✔ You prefer more traditional hunting-rifle ergonomics

✔ Your rifle spends significantly more time being carried than shot

✔ You primarily shoot from conventional hunting positions

✔ You want the FDX technology in a more traditional hunting configuration

The difference isn’t really one of better versus worse.

It’s about how you shoot.

The Elevation FDX is the more traditional hunting-oriented interpretation of the platform.

The Elevation MTR FDX is the more technical, precision-oriented interpretation.

Why the MTR FDX Makes Sense for the Modern Hunter

Modern hunting rifles have changed.

Hunters are increasingly using:

✔ Dialable precision optics

✔ Laser rangefinders

✔ ARCA tripods

✔ Lightweight bipods

✔ Ballistic solvers

✔ High-BC projectiles

✔ Long-range training techniques

Yet many still want a rifle weighing less than 3kg before optics.

The Elevation MTR FDX addresses exactly that requirement.

It combines the portability expected from a premium mountain rifle with the ergonomics and interfaces of a modern precision rifle.

The PROOF Research Elevation MTR FDX may be the most complete expression yet of PROOF’s Mountain Technical Rifle concept.

Its raised-comb, near-vertical-grip carbon fibre MTR stock gives the shooter the control and repeatability expected from a precision rifle, while its Falkor Defense LW7 action, PXT Sendero carbon fibre barrel, TriggerTech trigger, Hawkins M5 Hunter DBM and Salmon River Solutions ARCA/Picatinny rail provide a thoroughly modern technical foundation.

Most importantly, PROOF achieves all of this while keeping factory weight between approximately 5lb 14oz and 6lb 8oz, depending on chambering.

For the hunter who wants to carry like a mountain rifle, shoot like a precision rifle and train with the same platform they take into the field, the Elevation MTR FDX is an exceptionally compelling package.
