Proof Research Zermatt TL3/SR3 LA Pre-Fit Carbon Fiber

Description

Product Overview

The Proof Research Zermatt TL3/SR3 LA pre-fit carbon fiber barrel is built for shooters who want top-tier accuracy with reduced weight and improved thermal performance. It starts with match-grade 416R stainless steel barrel blanks made in Proof’s firearms division, then the steel is turned to a lighter contour and wrapped with high-strength aerospace-grade carbon fiber using Proof’s PROOF Research ACD matrix resin. The result is an aerospace-grade composite barrel designed to cool faster, help maintain accuracy over longer sessions, and deliver durable performance in demanding conditions.

Key Features
