Proof Research Sig Cross Pre-Fit 6mm Creedmoor Carbon Fiber Barrel 18in

Description

Product Overview

The Proof Research Sig Cross pre-fit carbon fiber barrel for 6mm Creedmoor is engineered to combine lightweight handling with match-grade accuracy. It starts with a full-profile 416R stainless steel barrel blank made in Proof Research’s firearms division, then is turned down and wrapped with aerospace-grade carbon fiber impregnated with their proprietary resin matrix from PROOF Research ACD. The composite construction is designed to help the barrel shed heat efficiently, contributing to consistent performance during extended strings of fire.
