This is a Proof Research .264 caliber bolt-action barrel blank measuring 28 inches with a 1:8 twist and the M24 contour. It ships as a blank, meaning it arrives ready for your gunsmith to thread and chamber to your exact spec, whether you're building a 6.5 Creedmoor, 6.5 PRC, 6.5×47, or another 6.5mm cartridge. The 1:8 twist is a versatile choice for the .264 bore, stabilizing the heavier, high-BC match bullets that make 6.5mm so popular for long range work.
Proof machines their steel barrels in-house using the same process as their well-known carbon fiber line. Everything starts with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless that was developed alongside barrel makers specifically for match-grade rifle work. It offers a homogeneous microstructure for uniform hardness end to end, plus the machinability and polishability needed for consistent lapping and precise groove dimensions. Each barrel gets single-point cut rifled, hand lapped, and borescope inspected before it leaves the shop.
The M24 profile is a heavier tactical-style contour with a 1.20 inch shank diameter, tipping the scales right around 6 pounds 10 ounces at the full 28 inch length. That extra mass out front soaks up recoil, hangs steady on the bag or bipod, and holds point of impact through longer strings of fire. It's a natural fit for precision rigs, tactical builds, and any 6.5mm chambering where you want stability over featherweight carry.
Since this is a blank, plan on a trip to your gunsmith to have it fitted, chambered, and headspaced to your action. Do that, and you've got the bones of a seriously accurate 6.5mm shooter that should give you a long, dependable barrel life.
No, this ships as a blank, which means it is unthreaded and unchambered. Your gunsmith will need to thread it to your action, cut the chamber for your chosen 6.5mm cartridge, and set headspace. Once fitted, it becomes the barrel for a custom precision build.
The .264 bore covers the full family of 6.5mm cartridges, so popular options include 6.5 Creedmoor, 6.5 PRC, 6.5×47 Lapua, and 6.5-284. The 1:8 twist does a great job stabilizing the heavier, high-BC match bullets these cartridges are known for. Talk with your gunsmith about which chambering best suits your goals.
The M24 is a heavier tactical-style contour with a 1.20 inch shank, and at 28 inches it comes in around 6 pounds 10 ounces before chambering. That mass helps with recoil management and keeping the rifle steady on a bag or bipod. It is a great choice for precision and tactical rigs rather than lightweight mountain builds.
Proof machines their steel barrels in-house from double stress-relieved 416R stainless, the same steel core used in their carbon fiber line. Each blank is single-point cut rifled, hand lapped for a consistent bore, and borescope inspected before shipping. That process is what gives these barrels their reputation for accuracy and repeatability.
