Proof Research 22ARC Sendero Pre-Fit Carbon Barrel for Zermatt TL3 SR3 Origin and RimX

Description

Product Overview

The Proof Research 22ARC Sendero pre-fit carbon barrel is built for drop-in caliber changes and easy upgrades on Zermatt Arms TL3 / SR3 Origin and RimX actions. It uses a shouldered pre-fit design intended to thread on and be torqued down, leaving only the final headspace and alignment checks for your build.

Key Features

• Pre-fit shouldered barrel for simplified installation on Zermatt TL3 / SR3 Origin and RimX actions
• Sendero contour for a balanced handling feel while keeping weight down
• Carbon fiber construction with high-strength aerospace-grade carbon fiber and a proprietary resin matrix
• Lightweight design (up to 64% lighter than traditional steel barrels of similar contour)
• Improved heat dissipation for cooler, longer-lasting performance during extended strings

For shooters looking to update a build or swap calibers efficiently, this Proof Research pre-fit Sendero carbon barrel is engineered for consistent, durable performance.
