Proof Research AR-style barrel in .308 Winchester with 18" rifle-length gas system, 1:10" twist rate, and carbon fiber wrap for 64% weight reduction versus steel.
Proof Research has engineered a modern solution to the eternal problem of heavy rifle barrels: the PR15 combines a precision .308 Winchester bore with aerospace-grade carbon fiber construction that delivers genuine performance advantages.
The weight savings aren't merely cosmetic. A lighter barrel reduces overall rifle mass, decreases felt recoil, and improves handling without sacrificing accuracy. The improved heat dissipation means your barrel maintains zero shift better during rapid-fire strings and stays cooler to the touch—a genuine advantage in the field or on the range.
This is a purpose-built component for shooters who demand both performance and practicality.
