Proof Research Zermatt TL3/SR3 Pre-Fit 22 ARC 20in 1-7 Twist Sendero Carbon Fiber

Description

Product Overview

The Proof Research Zermatt TL3/SR3 pre-fit carbon fiber barrel is engineered for precision shooting with a lighter, cooler-running design. Starting with match-grade 416R stainless steel barrel blanks, Proof Research turns them to a reduced contour profile and then wraps the barrel with high-strength aerospace-grade carbon fiber using their proprietary ACD matrix resin. The result is a durable composite barrel that helps manage heat during extended sessions while maintaining consistent accuracy.

Key Features

• Carbon fiber overwrap for reduced weight and improved heat handling versus conventional profiles
• Match-grade 416R stainless steel core for precision-grade performance
• Sendero contour for a balance of rigidity and mass savings
• Designed as a TL3/SR3 pre-fit barrel for straightforward gunsmith installation
• Chambered in 22 ARC with the specified 20in length and 1-7 twist rate

Upgrade your TL3 or SR3 build with a carbon fiber composite barrel built for sustained accuracy—ideal for match and high-volume range sessions.
