Proof Research Elevation 2.0 Features The Proof Research Elevation 2.0 is built around PROOF PXT technology a rethinking of conventional rifling geometry and twist progression. By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore PXT lowers engraving force limits throat erosion and creates less felt torque during firing which helps the shooter stay on target. The manufacturer reports that PXT barrels have shown 30 to 100 percent gains in barrel life before measurable accuracy degradation and the barrel can handle higher pressure ammunition. With the Falkor Defense LW7 action and TriggerTech trigger the 7mm Backcountry rifle aims at consistent accuracy in demanding mountain conditions. The carbon fiber stock has integrated flush cups and a 13 5/8 length of pull and it suits hunters who spend long days climbing with their rifle. Up front the Salmon River Solutions SRS Combo Rail accepts both ARCA and Picatinny interfaces so bipods tripods and support gear mount securely. A 20 MOA pinned rail base sits on the receiver and Hawkins Precision M5 Hunter bottom metal feeds from a detachable box magazine. With the 5/8x24 muzzle protected by a supplied thread protector and a listed weight near 5 lbs 14 oz the short Elevation 2.0 stays nimble in tight country.
