Building a precision long-range rifle starts with a solid foundation, and the Proof Research 264 Cal 22" Sendero Light Contour carbon fiber wrapped barrel blank gives you exactly that—minus the weight penalty most shooters accept as inevitable. This .264 caliber barrel comes ready for your gunsmith to thread and chamber to your exact specifications, with a 1:8" twist rate and 4 grooves engineered for consistent bullet stability across a range of projectiles. The Sendero Light Contour profile balances stiffness with weight savings, making it an excellent choice for hunters and long-range shooters who log serious miles on foot or spend hours glassing from uncomfortable positions.
Proof Research's carbon fiber wrapping technology delivers genuine ballistic advantages without compromising durability or accuracy. The barrel blank is up to 64% lighter than a traditional steel barrel of equivalent strength, which translates to less fatigue during extended shooting sessions and faster sight-on when you're managing recoil and follow-up shots. Carbon fiber naturally dissipates heat more efficiently than steel, helping the barrel stay cooler during high-volume shooting and extending the window before thermal expansion affects point of impact. That stability matters at distance: you get minimal harmonic vibration and the precision you need for match-grade accuracy without the surprises that can come from barrel heating.
Beyond the performance gains, Proof Research barrels are built to shrug off field use. The carbon fiber wrap is nearly impervious to weather, dings, scratches, and the casual abuse that comes with hunting and range work—no babying required. The finish is tough, the engineering is meticulous, and the result is a barrel blank that handles like a premium component from day one.

This is a finished barrel blank—not a completed, installed barrel. It arrives ready for a qualified gunsmith to thread the breech end and chamber it to your desired specifications and firearm design.
Proof Research's carbon fiber wrapped construction is up to 64% lighter than a traditional steel barrel of comparable strength and contour.
No. The improved heat dissipation and reduced harmonic vibration of the carbon fiber design minimize the thermal expansion and barrel movement that typically cause point-of-impact shift during high-volume fire.
Yes. The carbon fiber wrap is nearly impervious to weather, nicks, dings, and scratches, making it well-suited to hunting and range work without special protection.
