Proof Research PR15 308 Win 20" Rifle Barrel

Proof Research PR15 Carbon Fiber Barrel

Proof Research has engineered a revolutionary approach to rifle barrel construction by wrapping high-strength, aerospace-grade carbon fiber around a precision-rifled steel core. The result is a barrel that delivers the accuracy and durability you expect while dramatically reducing weight and improving thermal performance.

Key Features

• Weight Reduction: Up to 64% lighter than traditional steel barrels of comparable contour
• Superior Heat Dissipation: Carbon fiber wrap disperses heat more efficiently, keeping your barrel cooler during extended shooting sessions
• Extended Barrel Life: Cooler operating temperatures translate to longer barrel longevity
• Aerospace-Grade Construction: High-strength carbon fiber impregnated with proprietary matrix resin for maximum durability
• Specifications:
  • Caliber: 308 Winchester
  • Length: 20"
  • Gas System: Rifle length
  • Twist Rate: 1:10"
  • Groove Profile: 5 grooves
  • Threading: 5/8-24 tpi

Why Carbon Fiber?

The carbon fiber wrap isn't just about weight savings. By reducing barrel mass while maintaining structural integrity, Proof Research barrels cool faster between shots and recover more consistently. This means better accuracy over sustained fire and a more manageable shooting experience, whether you're at the range or in the field.

This is a professional-grade component for shooters who demand precision and reliability.
