Proof Research Deep Impact CF 308 Win Barrel 20in 1:10 Black

Description

Product Overview

Proof Research Deep Impact CF barrel for 308 Win is built with a 416R stainless steel liner and a carbon fiber outer for a lighter, stiffer platform than traditional steel barrels. At 20 inches with a 1:10 twist and 5/8-24 muzzle threads, it’s engineered for match-grade accuracy, improved heat dissipation, and more consistent performance during extended strings.

Key Features

• 416R stainless steel and carbon fiber construction for reduced weight with sustained rigidity
• Deep Impact design to help reduce harmonic barrel vibration for consistent accuracy
• Improved heat dissipation for cooler operation and longer service life
• Help reduce point-of-impact shift during high-volume fire
• Match-grade accuracy with stable performance under heat

If you’re building or upgrading a 308 Win bolt-action, this Proof Research carbon fiber barrel configuration delivers a lightweight, precision-focused upgrade with proven stability.
