Multi-Layer Composite Heat Release Barrel Technology from Avient Accelerates Heat Transfer for Improved Shooting Performance

Avient Corporation, a premier provider of specialized and sustainable material solutions and services, announced the launch of its Composite Heat Release technology for firearm barrels.

Composite Heat Release is a new, patent-pending, multi-layer composite material innovation that incorporates layers of ceramic and carbon fiber reinforced composites applied to original equipment steel barrel bores. The material composition of the Composite Heat Release technology applies the concept of thermal inertia to speed heat transfer from the steel through the composite sleeve. This reduces barrel bore temperature over multiple firing rounds, reduces total barrel weight, and increases stiffness to improve overall sport shooting and hunting performance.

In a unique and collaborative design and fabrication process, Avient applies the composite materials onto Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) compliant steel barrel blanks supplied by the firearm manufacturer to Avient. Using their own steel bores combined with Avient’s composite technology, firearm manufacturers can achieve specific properties customized to their barrel requirements, such as weight, length, and other performance needs.

“Our technical specialists work closely with our firearms customers to elevate their brands with new, groundbreaking barrels that are highly customized,” said Mike Mosley, General Manager, Advanced Composites at Avient. “Unlike traditional carbon fiber wrapped barrels, our Composite Heat Release materials are specifically formulated to remove heat from the internal steel bore. Because of this, barrels made with this technology heat slower and cool faster than the competition.”
