The Proof Research .264 28-inch M24 Stainless Bolt Action Barrel (brand part no. 101094) is a match-grade barrel built for long-range 6.5mm shooters who want a proven military-pattern contour on a custom bolt-action build. Machined in the M24 contour, a heavier profile borrowed from the U.S. Army’s M24 Sniper Weapon System, this barrel gives a long-range rifle the mass it needs for consistent heat management and sustained accuracy through a string of shots. It’s chambered in .264 caliber and cut with a 1:8 twist rate to stabilize the heavier, longer 6.5mm bullets favored for extended-range work.
