US12345492 - Hybrid heterogeneous material baffle for firearm noise suppressor

Provided is a firearm noise suppressor baffle formed of at least two material zones. The zones are made of materials having dissimilar coefficients of thermal expansion from each other and have an interface substantially transverse to a bore axis. The baffle includes an annularly interrupting gap having a width. The gap is formed in at least one of the material zones and extends substantially longitudinal relative to the bore axis from an edge of the baffle.

The patent describes a firearm noise suppressor baffle made from at least two material zones with differing thermal expansion coefficients, designed to enhance performance by managing heat and sound. It features a conical shape with a projectile passageway and includes an annular gap that extends longitudinally, contributing to its functionality.

Claim 1

A firearm noise suppressor baffle having a substantially conical portion with a narrowed end and a projectile passageway at the narrow end, the conical portion being formed of at least two material zones, the material zones being made of materials having dissimilar coefficients of thermal expansion from each other with an interface substantially transverse to a bore axis that integrally fuses the material zones together, the baffle including an annularly interrupting gap having a width, the gap formed in at least one of the material zones and extending substantially longitudinal relative to the bore axis from an edge of the baffle.
