The Proof Research Elevation MTR is a left-hand bolt-action rifle chambered in 338 ARC, built around a Zermatt Arms Origin action. The lightweight build starts with a Sendero contour, carbon fiber-wrapped, match-grade barrel with a 1:8 twist for 338 ARC. The muzzle is finished and threaded 5/8-24 with a thread protector, so you can fit a compatible muzzle device. The rifle is test fired and backed by a sub MOA accuracy guarantee, so you start with a stated accuracy promise from the maker.

A TriggerTech trigger gives the Origin action its fire control. The lightweight carbon fiber stock comes in Midnight and has a 13 5/8 inch length of pull. A single piece pinned rail base gives you a mounting platform for your optic. Feeding comes from a detachable box magazine, and the modified ball bolt knob gives you a shaped handle for cycling the bolt.
