Proof Research Carbon Fiber Barrel Blank .224 22" Sendero Contour

The Proof Research .224 caliber carbon fiber barrel blank delivers match-grade accuracy with significant weight reduction compared to all-steel barrels. This 22-inch blank features Proof's proprietary carbon fiber wrap around a precision-lapped stainless steel core, combining the thermal stability and rigidity of carbon fiber with the accuracy of a match-grade bore. The Sendero contour offers an optimal balance of stiffness and weight savings for precision rifle builds in .224 caliber chamberings like .223 Remington, 5.56 NATO, and .224 Valkyrie.

This is an unfinished barrel blank requiring chamber reaming, threading, crowning, and fitting by a qualified gunsmith. The carbon fiber construction dissipates heat efficiently during extended shooting sessions while maintaining a consistent point of impact. Proof Research barrels are known for sub-MOA accuracy potential when properly installed and paired with quality components. Each blank is manufactured in the USA using aerospace-grade carbon fiber and stainless steel.
