Proof Research

The Proof Research Elevation 2.0 MTR in .338 ARC with a 16.5-inch barrel is a left-handed mountain tactical rifle built for hunters and precision shooters who demand accuracy without excess weight. This is a factory-tested, no-compromise platform: it pairs Proof Research's match-grade carbon fiber barrel with a Zermatt Arms Origin action, TriggerTech trigger, and proprietary carbon fiber stock—all engineered to deliver sub-MOA performance straight out of the box. At 6 lbs 7 oz to 7 lbs 2 oz depending on optics and accessories, the Elevation 2.0 LH .338 Arc strips away dead weight while keeping the rigidity and consistency that long-range precision demands.
The .338 ARC cartridge has earned its place among hunters and long-range competitors for delivering serious terminal performance in a package that doesn't require a magnum action or recoil management. In a left-hand configuration, this rifle opens that capability to southpaw shooters—a segment often forced to compromise or pay custom prices. The 16.5-inch Sendero contour barrel threads at 5/8-24 (thread protector included) and feeds from a reliable detachable box magazine, letting you transition between hunting and range work without gunsmithing. The single-piece pinned rail accepts any optic mount and the tan/FDE stock blends into backcountry terrain.
Every Elevation 2.0 leaves Proof's shop test-fired and verified to shoot inside MOA. The TriggerTech trigger is tuned for clean breaks without creep, and the modified ball bolt knob offers positive purchase in gloves. At this price point, you're not compromising on action quality, barrel match-grade precision, or materials—just getting smart engineering and direct-to-consumer efficiency.
